Answer 1

Haskell is a pure functional language that has a lazy evaluation feature. Haskell has the support of tree data structure as the given code has demonstrated it. The above code can be implemented in Haskell to get the desired output as per the user's requirement.

Tree data structure

The solution is as follows:

The given code is implemented in Haskell to count the number of elements in the tree (leaf or node), add up all the elements in a tree of numbers, Produce a list of the elements in the tree via an inorder traversal, Convert a Tree2 into an equivalent Tree1 (with the same elements).

First, we will define num_elts to count the number of elements in the tree (leaf or node) as follows:

num_elts :: Tree2 a -> Int num_elts (Leaf a) = 1 num_elts (Node2 a left_subtree right_subtree) = 1 + (num_elts left_subtree) + (num_elts right_subtree)

Then, we will define sum_nodes2 to add up all the elements in a tree of numbers as follows:

sum_nodes2 :: Num a => Tree2 a -> a sum_nodes2 (Leaf a) = a sum_nodes2 (Node2 a left_subtree right_subtree) = a + (sum_nodes2 left_subtree) + (sum_nodes2 right_subtree)

We will define inorder2 to produce a list of the elements in the tree via an inorder traversal as follows:

inorder2 :: Tree2 a -> [a] inorder2 (Leaf a) = [a] inorder2 (Node2 a left_subtree right_subtree) = inorder2 left_subtree ++ [a] ++ inorder2 right_subtree

Finally, we will define conv21 to convert a Tree2 into an equivalent Tree1 (with the same elements) as follows:

conv21 :: Tree2 a -> Tree a conv21 (Leaf a) = Leaf a conv21 (Node2 a left_subtree right_subtree) = Node (conv21 left_subtree) a (conv21 right_subtree)

Explanation: In the given code, the tree data structure is implemented. num_elts is defined to count the number of elements in the tree (leaf or node). sum_nodes2 is defined to add up all the elements in a tree of numbers. inorder2 is defined to produce a list of the elements in the tree via an inorder traversal. conv21 is defined to convert a Tree2 into an equivalent Tree1 (with the same elements).The code for num_elts, sum_nodes2, inorder2, and conv21 is defined, which can be implemented in Haskell for the desired output. In Haskell, the defined code can be implemented as per the requirement of the user. Hence, the solution is as mentioned above.  

Conclusion: Haskell is a pure functional language that has a lazy evaluation feature. Haskell has the support of tree data structure as the given code has demonstrated it. The above code can be implemented in Haskell to get the desired output as per the user's requirement.

Answer 2

The `conv21` function converts a `Tree2` into an equivalent `Tree` by recursively converting the left and right subtrees and creating a new `Node` with the converted subtrees and the current node's value.

To implement the required functions for the `Tree2` data structure in Haskell, you can follow these guidelines:

```haskell

-- Import the Tree data type from a previous question

import Tree

-- Count the number of elements in the tree (leaf or node)

num_elts :: Tree2 a -> Int

num_elts (Leaf _)     = 1

num_elts (Node2 _ l r) = 1 + num_elts l + num_elts r

-- Add up all the elements in a tree of numbers

sum_nodes2 :: Num a => Tree2 a -> a

sum_nodes2 (Leaf x)       = x

sum_nodes2 (Node2 x l r)  = x + sum_nodes2 l + sum_nodes2 r

-- Produce a list of the elements in the tree via an inorder traversal

-- Again, feel free to use concatenation (++)

inorder2 :: Tree2 a -> [a]

inorder2 (Leaf x)       = [x]

inorder2 (Node2 x l r)  = inorder2 l ++ [x] ++ inorder2 r

-- Convert a Tree2 into an equivalent Tree1 (with the same elements)

conv21 :: Tree2 a -> Tree a

conv21 (Leaf x)       = Leaf x

conv21 (Node2 x l r)  = Node (conv21 l) x (conv21 r)

```

In the code above, the `num_elts` function counts the number of elements in the tree by recursively adding up the number of elements in the left and right subtrees, plus 1 for the current node.

The `sum_nodes2` function recursively sums up all the numbers in the tree by adding the value of the current node to the sums of the left and right subtrees.

The `inorder2` function performs an inorder traversal of the tree, returning a list of elements. It concatenates the inorder traversal of the left subtree, the current node, and the inorder traversal of the right subtree.

The `conv21` function converts a `Tree2` into an equivalent `Tree` by recursively converting the left and right subtrees and creating a new `Node` with the converted subtrees and the current node's value.

Note that you will need to have the `Tree` data type available for the `conv21` function to work correctly.

Search and read and try to learn what is the Lex? How it work?
Is there a specific syntax for the Lex code? Can we use IDE to
write a Lex code?
i want to answer the quostions with the explaintion

Answers

1. Lex is a lexical analysis tool used for generating lexical analyzers, also known as scanners, for programming languages or other formal language specifications. It works by recognizing and tokenizing input text based on a set of user-defined rules and patterns.

Lex is a popular tool that helps in the creation of lexical analyzers. A lexical analyzer is an essential component of a compiler or interpreter that breaks down the input code into a sequence of tokens. Lex operates by defining a set of rules and patterns called regular expressions that describe the desired tokens to be identified.

Lex uses a rule-based approach, where each rule consists of a regular expression pattern and an associated action. When given an input file, Lex scans the text and matches the patterns defined in the rules. Once a match is found, the associated action is executed, which can include actions like generating code or returning the matched token.

Regarding the syntax of Lex code, it follows a specific structure. The Lex code consists of three main sections: definitions, rules, and user code. The definitions section defines macros and regular expression patterns used in the rules section. The rules section specifies the patterns and corresponding actions. The user code section allows for additional code to be included.

While Lex does not have a dedicated IDE, it can be written using any text editor and compiled using the Lex compiler. Many integrated development environments (IDEs) provide support for Lex by offering syntax highlighting and integration with other programming tools, making it easier to work with Lex code.

Answers

To allow ChoiceQuestion::display() to override Question::display(), the following change should be made:

ChoiceQuestion::display() needs to be explicitly declared virtual.

The change that needs to be made is to explicitly declare the ChoiceQuestion::display() function as virtual. By doing so, we indicate that this function is intended to be overridden by derived classes. In the given code, the display() function in the base class, Question, is already declared as virtual. However, the derived class, ChoiceQuestion, does not explicitly declare the display() function as virtual. This means that it is hiding the base class's display() function instead of overriding it.

By adding the "virtual" keyword in front of the display() function in the ChoiceQuestion class, we ensure that it overrides the display() function in the base class.

This allows polymorphic behavior, meaning that when we call the display() function on a ChoiceQuestion object through a pointer or reference of the base class type, the derived class's display() function will be invoked.

In this question, an RSA encryption-decryption system is built. (a) Choose two prime numbers between 10 and 20 and assign them as p and 9. (b) Then propose another integer as E and write the public key (E, N). Choose also E between 10 and 20. (c) Compute the private key D and show your work (d) Encrypt the plainnumber 25 to obtain the ciphernumber C (e) Now decrypt C with your system to obtain the plainnumber 25 again.

Answers

Given data:The two prime numbers between 10 and 20 are p = 13, q = 17.The plain number to be encrypted is m = 25.Working Steps:a) The two prime numbers are given in the problem, p = 13, and q = 17. Hence, their product N = p x q = 13 x 17 = 221.

b) Now, we need to propose another integer E such that it is co-prime to (p - 1) x (q - 1).

Here, we can select E = 5 because it is co-prime to (p - 1) x (q - 1).

So, the public key is (E, N) = (5, 221).c) The private key D can be calculated using the formula D x E mod (p - 1) x (q - 1) =

Substituting the values,

we get

D x 5 mod 192 = 1

Now, to solve this equation, we need to check the values of D starting from 1 because E = 5 is small. So, by hit and trial method,

D = 77 satisfies the equation.

Hence, the private key is D = 77.

d) Now, to encrypt the plain number 25, we will use the formula C = m^E mod N.Substituting the values, we getC = 25^5 mod 221 = 113.

So, the cipher number is C = 113.e)

To decrypt the cipher number, we will use the formula m = C^D mod N.Substituting the values, we getm = 113^77 mod 221 = 25. So, the plain number is m = 25.

Hence, we have successfully encrypted and decrypted the plain number 25 using the RSA encryption-decryption system.

Answers

The given values are 20-bit virtual addresses, 2KB pages, 16-bit physical addresses. To find the total size of the page table (in Bytes) for each program, we must first calculate the number of entries in the page table and then multiply it by the number of bits per entry.

Using the formula we can determine the number of entries in the page table:# entries = (size of virtual address space) / (page size)= 2^20 / 2^11= 2^9= 512 entriesThe given "4 bits per page table entry" indicates the number of bits required to store the physical page frame number for each virtual page in the page table.

Therefore, we can now calculate the total size of the page table (in Bytes) for each program as follows:Size of page table = (# entries) x (# bits per entry) / 8= (512) x (4) / 8= 256 BytesHence, the answer is option D. 256 bytes.

Obtain the natural frequency and the damping ratio of the system.

Given: 6y(t) + 15y'(t) + 27y"(t) = 23u(t) The transfer function can be obtained by applying Laplace transform to the given differential equation.Let us take Laplace transform on both sides.

L{6y(t)} + L{15y'(t)} + L{27y"(t)} = L{23u(t)}

⇒ 6L{y(t)} + 15sL{y(t)} - 15y(0) + 27s²L{y(t)} - 27sy(0) - 27y'(0) = 23/ s

⇒ L{y(t)} (6 + 15s + 27s²) = 23/s + 15y(0) + 27sy(0) + 27y'(0)

⇒ L{y(t)} = (23/s + 15y(0) + 27sy(0) + 27y'(0))/ (6 + 15s + 27s²)

Putting s² + 2ζω ns + ω n² in denominator, and comparing the coefficients of s² and s and the constant terms separately we get the values of ω n and ζ.

6 + 15s + 27s² = 27(s + 0.9259) (s + 0.3264) (s + 0.1482)L{y(t)}

The combination of having the interface IP addresses on the same subnet, using the same Process ID, same OSPF Dead interval, and the same OSPF router ID would prevent the routers from becoming OSPF neighbors.

What combination of settings would prevent two routers from becoming OSPF neighbors?

In order to prevent two routers from becoming OSPF neighbors, the following combination of settings would be required:

a. The interface IP addresses of both routers are on different subnets. If the routers have overlapping IP addresses on the same subnet, they will not form OSPF neighbor relationships.

b. The routers use different Process IDs. Each OSPF process is identified by a unique Process ID, and routers with different Process IDs will not form neighbor relationships.

c. The routers' interfaces use different OSPF Dead intervals. The Dead interval is the time interval after which a router declares a neighbor as unreachable. If both routers have the same Dead interval, it may result in conflicts and prevent neighbor formation.

d. The routers are using different OSPF router IDs. The router ID is a unique identifier assigned to each router in an OSPF domain. If both routers have the same router ID, they will not establish OSPF neighbor relationships.

By ensuring these settings are different between the routers, it would prevent them from becoming OSPF neighbors.

#include <iostream>

using namespace std;

class B {

public:

   virtual void t() {

       cout << "Inside class B" << endl;

   }

};

int main() {

   B* b = new D();

   b->t();

   delete b;

   return 0;

}

In this code, we have a base class `B` and a derived class `D` that overrides the `t()` function. Inside the `main()` function, we create a pointer `b` of type `B` pointing to an object of type `D`.

When `b->t()` is called, it invokes the `t()` function based on the actual object type being pointed to, which is `D` in this case. Therefore, the output of the program will be:

Inside class D

This is because the `t()` function in class `D` is called due to dynamic polymorphism and the use of the `virtual` keyword in the base class.

Let G be a directed weighted graph with n vertices and m edges such that the edges in G have positive weights. Let (u, v) be an edge in G. By a shortest cycle containing edge (u, v) we mean a cycle containing (u, v) that is of minimum weight, among all cycles containing (u, v) (if such a cycle exists). Give an O(mlgn)-time algorithm that computes a shortest cycle in G containing the edge (u, v), or reports that no cycle containing edge (u, v) exists.

Answers

An O(mlgn)-time algorithm that computes a shortest cycle in G containing the edge (u, v), or reports that no cycle containing edge (u, v) exists can be given as follows:Let's start by adding a new vertex w to the graph. For each edge (u, v) in the original graph G, add two edges (u, w) and (w, v), both having the same weight as the original edge (u, v).

The shortest path from u to v in the new graph is the shortest cycle containing the edge (u, v) in the original graph. This is true because in the shortest path, we traverse the edge (u, v) and then return to u by traversing (v, w) and (w, u) in the opposite order, thus forming a cycle containing the edge (u, v). Therefore, if we remove the edges (u, w) and (w, v) from this cycle, we get a cycle containing only the edge (u, v).We can find the shortest path from u to v in the new graph using Dijkstra's algorithm, which takes O(mlgn) time. If the shortest path has length greater than the weight of the edge (u, v), then there is no cycle containing (u, v) in the original graph. Otherwise, we construct the cycle as described above and output it as the answer.

Support Vector Machines (SVM)
Consider fitting an SVM with C > 0 to a dataset that is
linearly separable. Is the resulting decision boundary guaranteed
to separate the classes?

Answers

Yes, the resulting decision boundary is guaranteed to separate the classes if they are linearly separable.

Support Vector Machines (SVM) is a supervised machine learning algorithm that is used for classification and regression analysis. SVMs can be used to classify data that is linearly separable. A linearly separable dataset is one where the data points belonging to different classes can be separated by a straight line or a hyperplane in a multi-dimensional space.

The decision boundary of an SVM is the hyperplane that separates the different classes. If the data is linearly separable, then the SVM can find the hyperplane that maximizes the margin between the classes. This margin is the distance between the decision boundary and the closest data points of each class.

The SVM algorithm aims to find the hyperplane that separates the data with the largest margin. The decision boundary is guaranteed to separate the classes if they are linearly separable. However, if the data is not linearly separable, then the SVM algorithm tries to find the hyperplane that separates the data with the smallest classification error. In this case, the resulting decision boundary may not be able to separate the classes perfectly.

What will appear on the screen?

Answers

as a summary, When running the given program, the message "no match" will appear on the screen. This is because the condition specified in the if statement is true since 5 is not equal to 6, and thus, the echo command within the if block will be executed.

The program begins by assigning the value 5 to the variable "a" and the value 6 to the variable "b". In the subsequent line, the if statement checks if the value of "a" is not equal to the value of "b" using the "-ne" operator. Since 5 is indeed not equal to 6, the condition evaluates to true.

When the condition is true, the code block enclosed within the if statement is executed. In this case, the code block contains the echo command, which outputs the message "no match" to the screen. Therefore, when running the program, the message "no match" will be displayed as the result.

2. The following is a dump (contents) of a UDP header in hexadecimal format
0045DF0000580000
a. what is the source port number?
b. what is the destination port number?
c. what is the total length of the user datagram?
d. what is the length of the data?
e. what is the application layer protocol?

Answers

a. Source port number: 69

b. Destination port number: 57152

c. Total length of the user datagram: 88 bytes

d. Length of the data: 80 bytes

e. Application layer protocol: Not determinable from the provided information.

To analyze the UDP header dump, let's break down the hexadecimal representation:

```

0045 DF00 0058 0000

```

a. The source port number is the first 2 bytes (16 bits) of the UDP header. In this case, it is `0045` in hexadecimal, which is `69` in decimal.

b. The destination port number is the next 2 bytes (16 bits) of the UDP header. In this case, it is `DF00` in hexadecimal, which is `57152` in decimal.

c. The total length of the user datagram is the next 2 bytes (16 bits) of the UDP header. In this case, it is `0058` in hexadecimal, which is `88` in decimal.

d. The length of the data can be calculated by subtracting the UDP header length (8 bytes) from the total length of the user datagram. In this case, it would be `88 - 8 = 80` bytes.

e. The application layer protocol is not directly indicated in the UDP header. UDP itself is a transport layer protocol. The application layer protocol is determined based on the port numbers used. Port numbers help identify the specific application or service running on the source and destination devices. To determine the application layer protocol, we would need to know the well-known port numbers associated with specific protocols.

In summary:

a. Source port number: 69

b. Destination port number: 57152

c. Total length of the user datagram: 88 bytes

d. Length of the data: 80 bytes

e. Application layer protocol: Not determinable from the provided information.

Consider a cache with 128 blocks. The block size is 32 bytes. Find the number of tag bits, index bits, and offset bits in a 32-bit address if you design it as a) Direct-mapped b) 8-way Set Associative

Answers

Direct-mapped: Index bits = 7, Offset bits = 5, Tag bits = 20

8-way Set Associative: Index bits = 4, Offset bits = 5, Tag bits = 23

What are the key differences between HTTP and HTTPS protocols?

a) Direct-mapped:

In a direct-mapped cache, each memory block maps to a specific cache block based on its index. The cache size is 128 blocks, and the block size is 32 bytes.

Number of index bits:

Since the cache is direct-mapped, each memory block maps to exactly one cache block. The total number of cache blocks is 128. To address these cache blocks, we need log2(128) = 7 bits.

Number of offset bits:

The block size is 32 bytes, which requires 5 bits to address (2^5 = 32).

Number of tag bits:

The remaining bits in the 32-bit address after accounting for index and offset bits are used for the tag. Therefore, the number of tag bits is 32 - 7 - 5 = 20 bits.

b) 8-way Set Associative:

In an 8-way set associative cache, each memory block can map to any one of the 8 cache blocks within a specific set. The cache size is still 128 blocks, and the block size is 32 bytes.

Number of index bits:

With 8 sets in the cache, each set contains 128 / 8 = 16 blocks. To address these sets, we need log2(16) = 4 bits.

Number of offset bits:

The block size is still 32 bytes, requiring 5 bits to address.

Number of tag bits:

Similar to the direct-mapped case, the remaining bits in the 32-bit address after accounting for index and offset bits are used for the tag. Hence, the number of tag bits is 32 - 4 - 5 = 23 bits.

Therefore, in a) direct-mapped cache, there are 7 index bits, 5 offset bits, and 20 tag bits. In b) 8-way set associative cache, there are 4 index bits, 5 offset bits, and 23 tag bits.

using 6-bit signed numbers perform the following decimal operations in binary. Indicate with x which operation has overflow. (a) 23+10 (b) 21−8

Answers

The addition of 23 and 10 in 6-bit signed numbers results in an overflow. The binary representation of the sum, 100001, exceeds the capacity of the 6-bit format, indicating an overflow condition.

To perform addition with 6-bit signed numbers, we need to convert the decimal numbers to their binary representations. Since we are using 6-bit signed numbers, the leftmost bit will represent the sign (0 for positive and 1 for negative), and the remaining 5 bits will represent the magnitude.

Conversion:

23 = 010111

10 = 001010

We add these binary numbers together, taking into account the sign bit:

 010111 (+23)

+ 001010 (+10)

------------

 100001

The result is 100001, which is the binary representation of -15. However, since we are working with 6-bit signed numbers, there is an overflow in this case. The leftmost bit should indicate the sign, but here it represents an overflow.

It is necessary to use more bits or a larger signed number representation to accommodate the sum of these two numbers.

Note: If we were working with 6-bit unsigned numbers, the sum would be 000001, which is the correct binary representation of 33. However, in this case, we are specifically using signed numbers.

option e) During a TLS handshake, the two asymmetric keys being used are the server's public key and the client's private key (option e).

The server's public key is used by the client to validate the authenticity and integrity of the server's certificate. The client's private key is used to generate the initial secret key and encrypt it before sending it back to the server. To prevent the fraud described in the scenario, the cybersecurity principle of Separation of Duties/Least Privilege (option a) should be implemented.

Write a program in python to assist the manager in calculating the weekly per person sale of the restaurant. The user will enter the daily number of customers visited and daily sales for a week and the system will provide the output.
Weekly per person average sale= Total sale for a week / Total number of persons visited in Week

Answers

The user inputs the daily number of customers visited and the daily sales for a week, and the program calculates the average sale per person for the entire week.

To implement this program, we can use a loop to iterate through the seven days of the week. On each iteration, the user is prompted to enter the number of customers visited and the sales for that particular day. We keep track of the cumulative total of customers and sales for the entire week. After the loop completes, we calculate the weekly per person average sale by dividing the total sales by the total number of customers visited.

The program code may look something like this:

```python

total_customers = 0

total_sales = 0

for day in range(1, 8):

   customers = int(input(f"Enter the number of customers visited on day {day}: "))

   sales = float(input(f"Enter the sales for day {day}: "))

   total_customers += customers

   total_sales += sales

average_sale_per_person = total_sales / total_customers

print(f"Weekly per person average sale: {average_sale_per_person}")

Answers

For an organization that requires seamless integration and sound security, a hybrid network topology would be recommended. This network type combines the strengths of different topologies, such as star, bus, or ring, to create a flexible and secure network infrastructure.

A hybrid network topology offers the advantages of multiple network topologies while addressing the specific needs of seamless integration and sound security. The organization can strategically design and implement a combination of topologies based on their requirements.

Seamless integration can be achieved by incorporating different topologies that cater to specific functions or departments within the organization. For example, a star topology can be used for critical systems that require centralized management and high-speed data transfer, while a bus or ring topology can be used for other areas where simplicity and scalability are important.

In terms of security, a hybrid network allows the organization to implement various security measures at different levels. For sensitive areas or critical data, they can employ dedicated security mechanisms like firewalls, intrusion detection systems, and encryption protocols. Simultaneously, less critical areas can benefit from shared security measures.

By combining different network topologies, the organization gains flexibility, scalability, and enhanced security, allowing for seamless integration of diverse systems while maintaining robust protection for their network infrastructure and data.

Exit: prints the information of step 3 to a file called shortest_path.txt and exits the program Grading policy: 1. Your application should have all functionalities working properly. Twenty marks will be graded for the functionality of the project; 2. The following notes will make up the remaining 10 marks of the grade: a. There has to be adequate documentation and comments in the code (i.e., functions, loops, etc.); b. Your code should follow the code convention (i.e., spaces, indentations, etc.); and c. Your application should contain a menu to allow the user to select which option (s) he would like to run. Notes and submission instructions: 1. This is individual work. It should represent your own efforts. It is fine to discuss your work and to ask your colleagues, but you are not allowed to copy/paste the work of others or give your work to anyone else. You are not allowed to post/copy from other websites and/or social media and this will be considered as cheating. 2. Any plagiarized code will not be marked. 3. Document format. Please submit only the code file (c file) containing the code of your project. Please rename it as follows: "P4_YourStudentID_FirstNameLastName_SectionNo.c". 4. Input/output file name. Make sure that the input/output file names are the same as in the specifications. 5. Include your full name, student ID, and section number in the beginning of your file. 6. Please do not compress the file, only the C-file is needed. 7. Files not following the convention in point 2 will not be marked. Simple explanation, please.

Recently, vere of th M.K. is a 43 year old male patient at a primary care visit. While reviewing the health history information with M.K., he tells you that he drinks 2 -3 glasses of red wine every day with dinner because he believes red wine is healthy and that it will protect him from having a heart attack. Upon further probing, M.K states that this is in addition to sometimes drinking "one or two beers" after he gets home from work. M.K. is 5' 11" tall and weighs 190 lbs. His blood pressure is 146/90.What would you advise M.K about his alcohol intake as it relates to his health? Write a brief script of this conversation. Your advice to M.K should be clear and specific about the risks and recommendations regarding alcohol consumption Show that if om is the phase-matching angle for an ordinary wave at w and an extraordinary wave at 2w, then 201 (n2u) -2 - (120) n24-2 sin(20m) (0 - 0m) 20n%) - Ak(Olo-om = -3 Co Given an integer array of positive single digit values such as: int a[] = {8,4,2,6,9}; 1) Write a recursive arrayToN function which returns the concatenation of all array values as an integer value. This function should accept all required data as parameters and return a long integer value. Examples If the array is 8 4 2 6 9 the arrayToN function returns the integer 84269. If the array is 0 2 6 8 9 3 5 1 the arrayToN function returns the integer 2689351 Write a program that determine the inverse Laplace and Fourier transforms of the transfer functions in VIII and plot their phase and magnitude spectra. do you see any similarities between the rituals of indigenous societies and rituals that we have in today's societies? (question 2) A bicycle wheel is rotationally accelerated at the constant rate of 1.2 rev/s2 a. If it starts from rest, what is its rotational velocity after 4 s? which of the following is a monomer used to build a biological polymer? triglyceride amino acid dna disaccharide Find the volume of a traffic cone shaped like a cone with radius7 centimeters and height 13 centimeters. Round your answer to twodecimal places. A 42-year-old female patient enters the clinic complaining of nausea, stomach cramps, and diarrhea. There is currently an outbreak of E. coli O157:H7 from consumption of raw sprouts in four states, which raises alarms. You collect a stool sample and send it to the lab for testing. To better separate commensal, non-STEC E. coli from the intestines with pathogenic E. coli O157:H7, you select Sorbitol-MacConkey agar to differentiate between the two. The results of the culture are shown. What is the proper interpretation of the experiment? The reason that we use vacuum pump in Rutherford Exp. Is A-To eliminate the noise of the signal B- Because alpha particles have long range in air C- To protect the detector from radiation dose D-To be able to change the angle of deflection E-Because alpha particles have short range in air A four-pole, 250 V, lap-connected DC shunt motor delivers 12 kW output power. It runs at a speed of 1200 rpm and draws armature and field currents of 59 A and 4 A, respectively. The total number of armature conductors is 500 and armature resistance is 0.15 ohm.
