The true statement about Blockchain is Blockchain is a trustless platform.

Blockchain is often referred to as a trustless platform because it eliminates the need for trust in a centralized authority or intermediary. Instead, it relies on a decentralized network of computers (nodes) that collectively maintain and validate the integrity of the blockchain.

In a blockchain, transactions are recorded in blocks, and each block contains a hash value that represents the transactions included in that block. This ensures the immutability of the recorded data, as any change in a transaction would result in a different hash value, making it detectable.

Users in a blockchain network can modify data in a transaction, but to do so, they would need to create a new transaction that reflects the desired changes. Modifying an existing transaction is not possible due to the immutability of the blockchain.

It is important to note that blockchain is a decentralized data structure, and the ledger is distributed across multiple nodes in the network. There is no central authority or trusted node that solely holds the blockchain. This decentralization enhances the security, transparency, and resilience of the blockchain system.

Therefore, the true statement is that blockchain is a trustless platform, as it operates in a decentralized manner, relying on cryptographic algorithms and consensus mechanisms to ensure security and integrity without the need for trust in a central entity.

To obtain the FM signal, the baseband signal must first be known. Two methods are used to acquire the FM signal; direct FM modulation and indirect FM modulation. In the first method, the message signal is directly superimposed on the frequency-modulated signal. The carrier wave is shifted by a fixed amount in the second approach, and the message signal is subsequently amplified. In the absence of a carrier, the message signal is distorted. This is referred to as the carrier shift.

Direct FM modulation technique:

This technique is mostly used in frequency modulation. Direct FM modulation is a method of producing FM in which the audio frequency signal varies the frequency of the carrier wave directly. The amplitude of the carrier wave remains constant during the modulation process. Direct FM modulation is most commonly used in broadcasting. Direct FM modulation is usually implemented using a variable reactance or varactor diode that is biased by a direct current voltage.

Indirect FM modulation technique:

In indirect FM modulation, the message signal is amplified before being used to modulate a carrier wave. The message signal is first amplified by a non-linear circuit such as a limiter, peak detector, or frequency multiplier. After that, the amplified signal is used to modulate the carrier frequency.

Advantages and disadvantages of SSB modulation over DSB modulation:

Single sideband modulation (SSB) is a technique that is more efficient than double sideband modulation (DSB). The primary benefits of SSB modulation over DSB modulation are as follows:

Advantages:

SSB modulation uses less bandwidth, and therefore radio spectrum allocation is more efficient.

SSB modulation needs less transmitter power, which reduces power consumption and costs.

The signal-to-noise ratio is higher, which means that the output quality is higher.

Disadvantages:

SSB modulation is more complex than DSB modulation.

The required receiver is complex, which results in increased cost.

SSB modulation requires more precise frequency alignment than DSB modulation.

A pushdown automaton (PDA) which accepts the following language L4: {u E {a,b}* : 3* |ula = 2 *|ulo + 1} can be constructed in the following manner.

Consider the input string u as w#t where w and t are substrings of u and # is a delimiter symbol used to divide w and t. Let's assume the length of the substring w is 3n, then it can be expressed as w = x1x2...x3n where xi is either a or b, and the length of the substring t is 2n + 1 which can be expressed as t = y1y2...y2n+1, where yi is either a or b.

Here are the states and transitions of the pushdown automaton:State q0: The automaton begins in this state and pushes $ to the stack and transitions to state q1. δ(q0, ε, ε) → (q1, $)

State q1: This state keeps reading symbols of w from the input tape and pushes them onto the stack until it has read all of w. δ(q1, ε, ε) → (q1, $) for all a, b ∈ {a, b}* and δ(q1, xi, ε) → (q1, xi) for 1 ≤ i ≤ 3n.

State q2: In this state, the automaton pops the symbols of w from the stack and reads the symbols of t from the input tape.

The automaton pushes a symbol onto the stack every time it reads two symbols from the input tape. δ(q2, ε, xi) → (q2, ε) for 1 ≤ i ≤ 3n and δ(q2, ε, ε) → (q3, ε) for all a, b ∈ {a, b}*.

State q3: This state checks if the stack is empty and halts the automaton if it is. δ(q3, ε, $) → (q4, ε)

State q4: This is a final state of the automaton that accepts the input string u. δ(q4, ε, ε) → (q4, ε) for all a, b ∈ {a, b}*

Let's take the difference between the temperature of water at 2pm and 2:25pm i.e., 26°C - 16°C = 10°C.The time interval is 25 minutes because the difference is given for this time interval.Using the formula of Newton's Law of Cooling, we have:T = (T_s) + (T_o - T_s)e^(-kt),where:T = temperature of the water at any timeT_s = temperature of surrounding

T_o = initial temperature of the waterk = constantt = time pa Substituting the values, we have:32 = 35 + (16 - 35)e^(-kt)32 - 35 = -19e^(-kt)-3 = -19e^(-kt)e^(-kt) = 3/19Taking the natural logarithm of both sides, we get:-kt = ln(3/19)t = (-1/k) ln(3/19)Now, let's find the value of k.Using the formula of Newton's Law of Cooling, we have:T = (T_s) + (T_o - T_s)e^(-kt)Substituting the values, we have:16 = 35 + (26 - 35)e^(-kt)-19 = -9e^(-kt)e^(-kt) = 19/9Taking the natural logarithm of both sides, we get:-kt = ln(19/9)t = (-1/k) ln(19/9)Substituting the value of k in the equation for time, we get:t = (-1/ln(3/19)) ln(19/9)Now, t = 10 minutes (approx)So, the temperature of the water will be 32°C after 10 minutes.

Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol that is used in the transport layer of the OSI model to provide a virtual circuit between the application layer and the network layer.

To send and receive packets, TCP relies on two fundamental algorithms: Go-Back-N and Selective Repeat.Go-Back-N and Selective Repeat are two main algorithms used in TCP. Go-Back-N is the most straightforward method for error recovery. It uses a sliding window to send and receive packets. The sending host continues to send a window of packets while the receiving host acknowledges the packets it has received successfully. When a packet is not acknowledged, the sending host retransmits the packet and all the subsequent packets within the window. The Selective Repeat algorithm is similar to the Go-Back-N algorithm, but it handles lost packets differently.

The receiving host sends a duplicate acknowledgment to the sending host, indicating that it has received the packets up to the missing packet, and the sender retransmits only the missing packet.The TCP protocol implements a hybrid of both Go-Back-N and Selective Repeat algorithm to deal with lost or corrupted packets. Hence, the answer is option 3. A hybrid between Go-Back-N and Selective Repeat.

public static void sieve(int[] array)

This function takes an integer array as its argument. The array should be initialized to the values 1 through the chosen number. The function modifies the array so that only the prime numbers remain; all other values are zeroed out. The following steps should be followed to implement this method:

Step 1: Initialize an array of integers with all values set to 1.
Step 2: For each integer starting from 2, if the integer is prime (i.e., its value in the array is still 1), mark all multiples of that integer as non-prime (i.e., set their value in the array to 0).
Step 3: The resulting array will contain all prime numbers between 2 and the chosen number.

public static void goldbach(int[] array)

This function takes the same argument as the previous method and displays each even integer between 4 and the chosen number with two prime numbers that add to it. The following steps should be followed to implement this method:

Step 1: Generate the array of prime numbers using the sieve method.
Step 2: For each even integer between 4 and the chosen number (inclusive), find the two prime numbers that add up to it (if they exist). This can be done efficiently by checking each prime number in the array to see if the difference between the even integer and the prime number is also prime. If it is, then we have found the two prime numbers that add up to the even integer.
Step 3: Display each even integer and its two prime summands, if they exist.

a) the number of bits used for encoding in this PCM scheme is 12. b)  the maximum signal frequency for this PCM scheme with a required outgoing data rate of 288 kbps is 144 kHz.

a. To calculate the number of bits used for encoding in a PCM scheme, we need to consider the signal-to-noise ratio (SNR) and the desired signal-to-quantization noise ratio (SQNR).

In PCM, the SQNR is given by the formula:

SQNR = 6.02 * (N + 1.76) dB

Where N is the number of bits used for encoding.

Given that the observed SNR is 74 dB, we can calculate the SQNR:

SQNR = 74 dB

Using the formula for SQNR, we can solve for N:

74 = 6.02 * (N + 1.76)

N + 1.76 = 74 / 6.02

N = (74 / 6.02) - 1.76

N ≈ 11.82

Since the number of bits used for encoding must be an integer value, we can round N to the nearest whole number. Therefore, the number of bits used for encoding in this PCM scheme is 12.

b. To calculate the maximum signal frequency for a required outgoing data rate in a PCM scheme, we need to consider the Nyquist-Shannon sampling theorem.

According to the Nyquist-Shannon theorem, the maximum signal frequency (fmax) is given by the formula:

fmax = (Data Rate) / 2

Given that the required outgoing data rate is 288 kbps, we can calculate the maximum signal frequency:

fmax = (288 kbps) / 2

fmax = 144 kHz

Therefore, the maximum signal frequency for this PCM scheme with a required outgoing data rate of 288 kbps is 144 kHz.

Two answers can be chosen for the output of the following code segment, which are "This is the Circle Class" and "This is the Oval Class".

First, the class Shape is created and prints "This is the Shape Class". The Circle class is then created and extends the Shape class. However, it doesn't print anything. Then, the Oval class is created and extends the Circle class. When the Oval class is created, it prints "This is the Oval Class" and then invokes the constructor of its super class, Circle. So, "This is the Circle Class" is also printed.

Therefore, the output of the code segment is "This is the Circle Class" and "This is the Oval Class". The option "No output as there is no method has been invoked in the Oval class" is incorrect because the constructor of the Circle class is invoked when the Oval class is created.

∫F.dr = (4/3) - (1/3) = 1`.Hence, the work done in moving a particle along the straight line from (0,0,1) to (2,0,0) is `1`.

For any `f(t,y,z), M. curl (grad f) da = 0` is a true equation. This equation can be justified with the proof given below -Given that,`f(t,y,z)` is a scalar field and `M` is a vector field. Then `grad f = (df/dx)i + (df/dy)j + (df/dz)k`.Now, `curl (grad f) = curl [(df/dx)i + (df/dy)j + (df/dz)k]`.

On computing, we get`curl (grad f) = (d^2f/dzdy) i + (d^2f/dxdz) j + (d^2f/dydx) k`Now, taking the dot product of `curl(grad f)` with the area element `da` of the plane surface `S`, we get:M . curl(grad f) da = M . [curl(grad f) . da]As per the Stoke’s Theorem, `curl(grad f).da = del x (curl(grad f)).n`. Here, `n` is a unit vector normal to the plane surface `S`.As `del x (curl(grad f)) = 0`, the entire expression equals `0`. Hence, we have `M . curl(grad f) da = 0`.Given that, `F(x, y, z) = zi + zzj + k` cuts a planar surface `S: 3x + 2y + 62 = 6`. To evaluate `∫F.da` over this surface `S`, we need to find out the normal vector `n` to the surface and the limits of the integral. The plane surface `S: 3x + 2y + 6z = 6` can be rewritten as `z = (6 - 3x - 2y) / 6`.

Resource Loading is a process of allocating resources for a project and deciding how many resources are needed, when they are required, and where they will be used. It is an essential step to create a project schedule. Resource leveling, on the other hand, is a process of redistributing resources in a project to meet the schedule's requirements.

Resource Loading is a process of allocating resources for a project and deciding how many resources are needed, when they are required, and where they will be used. It is an essential step to create a project schedule. Resource leveling, on the other hand, is a process of redistributing resources in a project to meet the schedule's requirements. Key features of Resource Loading and Levelling are explained below: Resource Loading: Resource Loading is the process of allocating resources and determining their appropriate time and usage. Resource loading is a crucial step for project managers to evaluate the amount of time and resources needed to accomplish each task. The following are the essential features of Resource Loading:

• Assigning necessary resources for each task.

• Identifying when resources are required.

• Identifying the type of resources needed.

• Identifying the availability of resources.

• Determining the quantity of resources needed. Resource Levelling: Resource leveling is a process of resolving resource overallocations and under allocations in a project schedule. The primary purpose of resource leveling is to balance the resource demands with resource capacity. The following are the key features of Resource Levelling:

• Rescheduling the tasks within a project.

• Identifying the time frame for each task.

• Ensuring the availability of resources.

• Identifying any conflicts in the project.

• Determining the best approach to meet the schedule requirements.

How Resource Loading and Resource Levelling Interact: Resource loading and levelling interact in several ways. In a project, resource loading occurs first, followed by resource levelling. Resource loading determines how many resources are required, while resource levelling determines when and where the resources will be used. Once the resources are loaded, resource leveling is performed to check whether the resource allocation is feasible or not. If any overallocation or underallocation of resources is identified, then resource leveling is performed to balance the resources' demands and capacity. Hence, resource loading and levelling are interdependent processes, and both are essential to create a project schedule. The project manager has to ensure that the resources are available, and the resource allocation is balanced to meet the project schedule requirements.

The statics default_1 and default_2 are used in one of the class Instructor's methods, some_func(): class Instructor: # class ("static") intended constants default_1 = "one" default_2 = "two" def some_func(self, name=default_1, address=default_2): Assume that the value of default_1 is changed during the program run by being assigned the string "NEW ONE". After that change, the client omits the arguments, during the call to some_func(),

as in inst_object.some_func()In such a scenario, the following values will be assigned to the local parameters name and address when some_func() begins executing: name = "NEW ONE", address = "two".Explanation:Python is a general-purpose, high-level programming language that is interpreted, dynamically typed, and garbage-collected. It was created in the late 1980s by Guido van Rossum as a successor to the ABC language.

Python's design philosophy prioritizes code readability and conciseness, and its syntax enables programmers to convey concepts with fewer lines of code than they would need in languages like C++ or Java.In Python, methods can be created inside classes to perform a specific task. A method is a collection of statements that are grouped together to accomplish a particular action.

When an instance of a class calls a method, the instance is passed to the method as the first argument. By convention, this argument is named self. The self parameter refers to the instance of the class. It is used to access variables that belong to the class. When a class is defined, you can use the keyword “self” to reference the object that you are working with.

This is because the object that you are working with is not an instance of the class, but rather an instance of a class that inherits from the original class.In the code given above, we can see that the class Instructor contains two statics default_1 and default_2 that are used in the some_func() method. As a result, the default values assigned to the name and address parameters in the some_func() method are "one" and "two", respectively.

The time complexities of the 10 Python functions are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 1.

Based on the given order of common time complexities, let's analyze the time complexities of the 10 Python functions:

1. The first function has a constant time complexity (O(1)) because it performs a fixed number of operations regardless of the input size.

2. The second function has a logarithmic time complexity (O(log n)) because it uses a logarithmic algorithm, such as binary search or certain divide-and-conquer algorithms.

3. The third function has a linear time complexity (O(n)) because it iterates over a list or performs a linear operation for each input element.

4. The fourth function has a linearithmic time complexity (O(n log n)) because it combines a linear operation with a logarithmic operation, typically found in efficient sorting algorithms like Merge Sort or Quick Sort.

5. The fifth function has a quadratic time complexity (O(n²)) because it contains nested loops where the number of iterations is proportional to the square of the input size.

6. The sixth function has a polynomial time complexity (O(n³), O(n⁴), etc.) because it involves multiple nested loops, with the degree of the polynomial indicating the number of nested loops.

7. The seventh function has an exponential time complexity (O(2ⁿ), O(3ⁿ), etc.) because it grows exponentially with the input size, often seen in brute-force algorithms or certain recursive functions.

8. The eighth function has a factorial time complexity (O(n!)) because it involves factorial operations, which grow extremely fast and make it highly inefficient for large inputs.

9. The ninth function does not fit into any of the above common time complexities.

10. The tenth function has a constant time complexity (O(1)) similar to the first function.

True: Abstract classes in Java can be used to define a common interface or capability that is shared by multiple subclasses.

1. True: Abstract classes in Java can be used to define a common interface or capability that is shared by multiple subclasses. These subclasses can then provide their own implementation of the abstract methods defined in the abstract class. This allows for polymorphism, where objects of different subclasses can be treated interchangeably based on their common abstract class.

2. True: When a class implements the ActionListener interface in Java, it must provide an implementation for the actionPerformed method. This method is invoked when an action event occurs, such as clicking a button or selecting a menu item. The actionPerformed method defines the specific actions to be taken in response to the event.

3. False: In Java, a "catch" clause must always be accompanied by a corresponding "try" clause. The try-catch block is used for exception handling, where code within the try block is monitored for exceptions, and if an exception occurs, it is caught and handled by the catch block.

4. True: Static methods in Java belong to the class itself and can be invoked without creating an instance of the class. They can be accessed using the class name followed by the method name. This is different from instance methods, which require an object of the class to be created before they can be called.

5. False: Objects of a superclass cannot directly call methods that are defined in its subclass. However, if the subclass overrides a method from the superclass, and an object of the subclass is treated as an instance of the superclass, then the overridden method in the subclass will be called when the method is invoked on the superclass object.

This is known as dynamic method dispatch and allows for polymorphism in Java.

The statement that is true is "Only 1" from the given options. The true statement is "Only 1," which states that the time complexity of the merge sort algorithm is O(n * log n) in all three cases.

The time complexity of the merge sort algorithm is indeed O(n * log n) in all three cases, regardless of the initial order or distribution of the elements. Merge sort is a divide-and-conquer algorithm that recursively splits the input array into smaller subarrays until each subarray contains a single element. It then merges these subarrays in a sorted manner to obtain the final sorted array. The merging process takes O(n) time, and the recursive splitting process has a time complexity of O(log n). Hence, the overall time complexity of merge sort is O(n * log n).

However, the other statements are not entirely accurate. While searching large unsorted arrays may require a significant amount of time and is generally less efficient than searching sorted arrays, it does not necessarily require an equal amount of time. The time complexity of searching depends on the algorithm used, and there are algorithms optimized for searching unsorted arrays.

Additionally, while sorting techniques like merge sort can be used to sort linked lists, it is not a requirement. Other sorting algorithms, such as insertion sort or selection sort, can also be used for sorting linked lists efficiently.

In conclusion, the true statement is "Only 1," which states that the time complexity of the merge sort algorithm is O(n * log n) in all three cases.
