(c.2) What is the worst-case complexity of your improved insertion sort if only swaps/inversions of the data values are taken into account?
The quicksort algorithm with median-of-three partitioning and a cutoff of 3 is executed on the given list of numbers. Its running time complexity is O(n log n).
(a) The given list of numbers is sorted using the quicksort algorithm with median-of-three partitioning and a cutoff of 3. The execution traces the steps involved in partitioning the list and recursively sorting the sublists.
(b) The running time complexity of the algorithm described by the given recurrence equation is O(n log n). This can be justified by applying the Master Theorem to the recurrence relation. The recurrence has the form T(n) = aT(n/b) + f(n), where a = 3, b = 3, and f(n) = 2cn. By comparing the parameters of the recurrence with the conditions of the Master Theorem, we find that a/b = 1, which falls into the case 2 of the theorem. Therefore, the running time complexity is O(n log n).
(c.1) The worst-case complexity of the improved insertion sort, considering only the comparisons made by the binary search, is O(log n). This is because binary search divides the input space in half at each step, resulting in a logarithmic time complexity for finding the correct insertion position.
(c.2) The worst-case complexity of the improved insertion sort, considering only the swaps/inversions of the data values, remains O(n^2). This is because even though binary search reduces the number of comparisons, the swaps/inversions required to shift elements and insert the new value still need to be performed in the worst case, resulting in a quadratic time complexity.
In conclusion, the quicksort algorithm with median-of-three partitioning and a cutoff of 3 is executed on the given list of numbers. Its running time complexity is O(n log n) according to the provided recurrence equation. The improved insertion sort with binary search for finding the insertion position improves the comparison complexity to O(log n), but the overall worst-case complexity remains O(n^2) considering the swaps/inversions of data values.

A 3-signal digital communication system, using S, (1), S₂ (1), S, (1) given by S, (t)=sin(271) Osi≤1 S₂ (t) = cos(271) Ostsl S, (1)=0 Osi≤1 All signals are equally likely. a) Find the signal-space representation and decision regions of the optimum detector. b) Find the probability P[error (t) was transmitted]. c) Find the probability P[S, (1) is decided | S, (t) was transmitted]
The probability that S1(1) is decided, given that S(t) was transmitted, can be found by dividing the area of the decision region that corresponds to S1(t) by the total area of the decision regions that correspond to S(t). P(S1(1) is decided | S(t) was transmitted) = 1/2.
The signal-space representation and decision regions of the optimum detector and other values of a 3-signal digital communication system have been asked.
The following is the solution to the problem:
Given: S1(t)=sin(2πt/T+0)S2(t)=cos(2πt/T+0)S3(t)=sin(2πt/T+0)S1(1)=0S2(1)=1S3(1)=2
All signals are equally likely.
a) Find the signal-space representation and decision regions of the optimum detector.
The signal-space representation is a three-dimensional coordinate system with each axis representing one signal.
Thus, each signal can be represented by a unique point in space, which can then be divided into decision regions.
In this system, the three signals are S1(t), S2(t), and S3(t).
The signals can be represented as follows:
Signal Space Representation
In the above figure, the points in the signal space represent the different signals. The dotted lines indicate the decision boundaries between the different signals.
The decision regions are defined by the boundaries between the signals, which are determined by the decision rule.
b) Find the probability P[error (t) was transmitted].
The probability of an error is the probability that the received signal was not the signal that was transmitted.
This can occur if the received signal is closer to another signal than the one that was transmitted.
Therefore, the probability of an error can be determined by finding the areas of the decision regions that do not correspond to the transmitted signal, and summing these areas.
The probability of error can be calculated using the following formula:
P(error) = P(choose S2 or S3 when S1 was transmitted) + P(choose S1 or S3 when S2 was transmitted) + P(choose S1 or S2 when S3 was transmitted)
P(error) = (Area of Region 2 + Area of Region 3) + (Area of Region 1 + Area of Region 3) + (Area of Region 1 + Area of Region 2)P(error) = (1/4 + 1/4) + (1/4 + 1/4) + (1/4 + 1/4)P(error) = 1/2c)
Find the probability P[S1(1) is decided | S(t) was transmitted]
The probability that S1(1) is decided, given that S(t) was transmitted, can be found by dividing the area of the decision region that corresponds to S1(t) by the total area of the decision regions that correspond to S(t).
P(S1(1) is decided | S(t) was transmitted) = Area of Region 1 / (Area of Region 1 + Area of Region 2 + Area of Region 3)P(S1(1) is decided | S(t) was transmitted) = 1/2.

Derive the equation for the Laplace transform of the cosine function in a similar approach to what is provided in the lecture for the sine function. f(t)=Coswt + F(s)= - (s ?
The equation for the Laplace transform of the cosine function in a similar approach is The Laplace transform of cos(wt) is F(s) = s / (s^2 + w^2).
To derive the equation for the Laplace transform of the cosine function, we can use Euler's formula, which states that cos(wt) can be expressed as (e^(jwt) + e^(-jwt))/2. Let's assume the Laplace transform of f(t) = cos(wt) is F(s).
Using linearity and the properties of the Laplace transform, we have:
F(s) = L[cos(wt)]
= L[(e^(jwt) + e^(-jwt))/2]
= (1/2) * (L[e^(jwt)] + L[e^(-jwt)])
Applying the property L[e^(at)] = 1 / (s - a), we get:
F(s) = (1/2) * (1 / (s - jw) + 1 / (s + jw))
= (1/2) * ((s + jw + s - jw) / ((s - jw)(s + jw)))
= (1/2) * (2s / (s^2 + w^2))
= s / (s^2 + w^2)
Therefore, the Laplace transform of f(t) = cos(wt) is F(s) = s / (s^2 + w^2).

. IF the maximum size of aggregate is 1.5 inch and slump is 5 inches, what is the maximum amount of cement needed?
The maximum amount of cement needed cannot be determined solely based on the maximum size of aggregate and slump. Additional information such as the desired concrete strength, mix design, and water-cement ratio is required to calculate the maximum amount of cement.
To determine the maximum amount of cement needed, we need to consider the volume of concrete required and the cement content per unit volume.
The volume of concrete can be calculated using the formula:
Volume = (1/27) x (L x W x H)
where L, W, and H are the dimensions of the concrete structure in feet.
Given that the maximum size of aggregate is 1.5 inches, we need to convert it to feet by dividing it by 12 (1 foot = 12 inches). So the maximum aggregate size is 1.5/12 = 0.125 feet.
Now, we need to subtract the slump from the height of the concrete structure to determine the effective height. In this case, the slump is given as 5 inches, which is 5/12 = 0.4167 feet.
Effective Height = H - Slump = H - 0.4167
Next, we need to consider the volume occupied by the aggregate. Since the maximum aggregate size is 0.125 feet, the volume occupied by the aggregate can be calculated as:
Aggregate Volume = (1/27) x (L x W x H) x (1 - (0.125)^3)
Finally, to find the volume of cement paste required, we subtract the aggregate volume from the total volume of concrete.
Cement Volume = Total Volume - Aggregate Volume
Once we have the cement volume, we can determine the amount of cement needed by multiplying it by the unit weight of cement.
Please note that the specific unit weight of cement may vary depending on the type of cement used.

Exercise 4 (20%) d'y dt² 1. A system is described by the differential equation +2 = 4 – 6. This system is definitely linear. (a) Yes (b) No
Answer: This system is definitely linear No.
Given the differential equation:+2 = 4 – 6d'y / dt²
From the given differential equation, we can see that the highest power of the dependent variable y is 2, therefore it is a second-order differential equation.
A linear system is a system where the variables are linearly related to one another. This means that if y is proportional to x, then the system is linear.
Mathematically, this means that the equation can be written in the form:y = ax + b
In other words, if the equation is linear, the power of the dependent variable will be 1. However, in the given differential equation, the power of y is 2, which makes it a non-linear equation.
Therefore, the system is definitely not linear.

The provided code is an implementation of the Monte Carlo method to approximate the value of pi. It generates a specified number of random points and calculates the ratio of points that fall within a unit circle to the total number of points generated. The code snippet is incomplete, but I can explain the general flow and purpose of the program.
The code starts by including the necessary header files and declaring variables for counting points inside the unit circle, iterating through the points, and storing the number of samples. It also includes an array `xi` to hold the random number seed.
The `main` function begins by checking the command-line arguments to ensure the correct syntax and extract the required values for the number of samples and random number seed.
After initializing the `count` variable to 0, the program enters a loop to generate the random points. It uses the `xi` array as the random number seed to generate random coordinates `x` and `y` within a range (0, 1).
Inside the loop, the program checks if the generated point `(x, y)` falls within the unit circle (radius = 1) by comparing the distance from the origin to the point. If the point is within the circle, it increments the `count` variable.
Once all the points have been generated and checked, the program calculates the approximation of pi using the formula `pi ≈ 4 * (count / samples)`, where `count` represents the number of points inside the unit circle and `samples` is the total number of points generated.
The program could include additional code to output the approximation of pi or perform further computations based on the calculated value.

Let G3 be a context-free grammar. S -> aSalbSb C C -> Cla a. Use the CFG -> NPDA algorithm to construct an NPDA M3 such that L(M3) = L(G). You must use the CFG -> NPDA algorithm found in the Chap 7.2 Power Point slides. Do not use the algorithm in the Linz text in Chap 7.2. It requires that your grammar be in Greibach normal form which will not always be true. Input your NPDA into JFLAP. b. Use JFLAP to test M3 on the strings: abbccbba, ccc, abcab, aabcbaa, abba, bbcbb. Upload the graph of M3 and the testcases and paste into your answer. c. What language is accepted by L(M3)? Give a simple English description. Justify your answer by describing what the machine M3 does.
After w has been processed completely, the machine M3 goes to state qf if the stack is empty; otherwise, it rejects the input string w. ii. If w is not of the form anbmcm, then the machine M3 rejects w immediately.
a) The CFG (Context-free Grammar) G3 is given below:S → aSalbSbC → Cla aThe CFG → NPDA algorithm is as follows:
Step 1: Make a start state q0 in the NPDA. Mark this state as the only initial state.
Step 2: Create a new final state qf in the NPDA. Mark this state as the only final state.
Step 3: For every terminal symbol a in the CFG, add a transition (q, a, ε, q) for every state q in the NPDA. ε is an empty stack symbol.
Step 4: For every rule A → α in the CFG, add a transition (q, ε, A, q') for every pair of states q, q' in the NPDA.
Step 5: For every rule A → aBβ and B → γ in the CFG, add a transition (q, b, B, q') for every b in the input alphabet and for every pair of states q, q' in the NPDA where there is a path from q to q' labeled by αβ.
Step 6: For every rule A → ε in the CFG, add a transition (q, ε, A, q') for every pair of states q, q' in the NPDA where there is a path from q to q' labeled by A. In addition, add a transition (qf, ε, ε, q0). Applying the above algorithm, the following NPDA M3 is constructed. The graph of the NPDA M3 is shown in the following diagram:
b) The strings are given below:abbccbbacccabcabaabcbaaababbacbbcbbThe NPDAs for the testcases are shown below: i. NPDA for the string abbccbba is shown below: ii. NPDA for the string ccc is shown below: iii. NPDA for the string abcab is shown below: iv. NPDA for the string aabcbaa is shown below: v. NPDA for the string abba is shown below: vi. NPDA for the string bbcbb is shown below:
c) The language accepted by L(M3) is the set of all strings with the same number of a’s, b’s, and c’s in them and having at least two a’s, two b’s, and two c’s in them. In other words, L(M3) = {w ∈ {a, b, c}* : na(w) = nb(w) = nc(w), na(w) ≥ 2, nb(w) ≥ 2, nc(w) ≥ 2}, where na(w), nb(w), and nc(w) denote the number of a’s, b’s, and c’s in w, respectively. The justification of this answer is as follows: M3 has three kinds of states: the start state q0, the intermediate states q1, q2, and q3, and the final state qf. The machine M3 makes the following checks for the input string w: i. If w is of the form anbmcm, then the machine M3 simulates the first rule S → aSalbSb of G3 by pushing a on the stack and going to state q1. From state q1, the machine M3 simulates the second rule S → ε by popping a from the stack and going to state q2. From state q2, the machine M3 simulates the third rule C → Cla by pushing c on the stack and going to state q3. From state q3, the machine M3 simulates the fourth rule C → a by popping c from the stack and staying in state q3. The machine M3 then goes back to state q1 to repeat the process for the remaining symbols in w. After w has been processed completely, the machine M3 goes to state qf if the stack is empty; otherwise, it rejects the input string w. ii. If w is not of the form anbmcm, then the machine M3 rejects w immediately.

The value of 30 sin 400t + 10 cos(400t+ 60°) - 5 sin(400t - 20%) is to be determined such that the magnitude is positive and all angles are in the range of negative 180 degrees to positive . cos(400t+(-120°)) is also to be determined.
Using the Euler’s formula, the given trigonometric function can be expressed as follows:$$30 \sin(400t) + 10 \cos(400t + 60^{\circ}) - 5 \sin(400t - 20^{\circ})$$Let A be the magnitude of the phasor and Φ be its phase angle in degrees, then the phasor can be expressed as follows:A ∠ Φ = 30 ∠ 0° + 10 ∠ 60° - 5 ∠ (-20°)Taking the sum of the first two phasors, we get,30 ∠ 0° + 10 ∠ 60° = (30 + 5√3) ∠ 30°Taking the difference of this phasor from the third phasor, we get,(30 + 5√3) ∠ 30° - 5 ∠ (-20°) = (30 + 5√3) ∠ 30° + 5 ∠ 160°Converting the above phasor to the rectangular form, we get,= (30 + 5√3) cos 30° + j(30 + 5√3) sin 30°+ 5 cos 160° + j5 sin 160°= 25 + 30√3 j - 4.98 j≅ 25 + 30√3 j - 4.98 j= 25 + 30√3 - 4.98 j≅ 5.017 - 47.226 j

REE-September 2007 4. The wye connected three-phase voltage source has \( V_{c}=115 \mathrm{Vrms} \) with \( -240^{\circ} \) angle. Find the line to line voltage \( V_{b c} \). A. \( -99-j 173 \mathrm
The line-to-line voltage, Vbc is -99 - j173Vrms.
In order to determine the line-to-line voltage Vbc, we must first determine the phase voltage of the wye-connected three-phase voltage source.
The phase voltage of a wye-connected three-phase voltage source is given by the formula below: Vp = [tex]\frac{V_{line}}{\sqrt{3}}[/tex]
where, Vline represents the line voltage of the source.
In this case, we know that the phase voltage is Vc = 115Vrms.
Therefore, we can solve for the line voltage of the source, using the formula above as follows: Vline = √3Vphase
Vline = √3×115V
Vline = 199.5Vrms
The line voltage of the source is thus Vline = 199.5Vrms.
The line-to-line voltage Vbc} can be determined using the formula below: Vbc = Vline∠-120°
where, Vline represents the line voltage of the source, and -120° is the phase angle between lines b and c for a three-phase system.
We can thus find the line-to-line voltage as follows: Vbc = 199.5V∠-120°
⇒ Vbc = -99 - j173Vrms

The specific volume of superheated water vapor at 0.1MPa and 500 ∘
C is 3.5655 m 3
/kg, determine the specific volume also using : (a) The ideal-gas equation. (5 points) (b) The generalized compressibility chart. (10 points) (c) Can we consider the superheated vapor to behave as an ideal gas under the given temperature and pressure? Why ? ( 5 points)
Factors such as the compressibility factor (Z), deviation from ideal gas equation predictions, and other thermodynamic properties can help assess the validity of the ideal gas assumption. A thorough analysis would be required to determine if the given conditions satisfy the ideal gas assumption.
a. To determine the specific volume of superheated water vapor using the ideal-gas equation, we can utilize the equation of state for ideal gases, which is given as:
PV = mRT,
where P is the pressure, V is the volume per unit mass (specific volume), m is the mass, R is the specific gas constant, and T is the temperature.
By rearranging the equation, we can solve for the specific volume:
V = RT/P.
Given the pressure P = 0.1 MPa and the temperature T = 500 °C, we need to convert the temperature to Kelvin before substituting the values into the equation. Once we have the temperature in Kelvin, we can calculate the specific volume using the ideal-gas equation.
b. To determine the specific volume using the generalized compressibility chart, we need additional information such as the critical properties of water. The generalized compressibility chart relates the compressibility factor (Z) of a gas to its pressure and temperature. By locating the point on the chart corresponding to the given pressure and temperature, we can determine the compressibility factor Z. Once Z is known, we can use it in conjunction with other thermodynamic properties to calculate the specific volume of the superheated vapor.
c. Whether we can consider the superheated vapor to behave as an ideal gas under the given temperature and pressure depends on the proximity of the actual behavior of the vapor to that of an ideal gas. Ideal gas behavior assumes that there are no intermolecular forces or significant deviations from the ideal gas law. However, at high pressures or low temperatures, real gases can deviate from ideal behavior due to intermolecular interactions.
To determine if the superheated vapor can be considered ideal, we need to compare its behavior with the assumptions of ideal gases.

1. Applications of timers:Timers are very important in microcontroller-based embedded system design. Here are some applications of timers:Real-time clock generationTimer interrupts - generating interrupts for a specific time generation in microseconds or millisecondsPulse-width modulation - PWM generation to control motor speed and led brightnessReading analog sensors - using an analog-to-digital converter with a timer to read the values of a sensor
2. Explanation of TMOD and TCON registers used to control timer operationsThe following two registers are used to control the timer operations:TMOD: Timer mode control registerTCON: Timer control registerThe timer mode control register (TMOD) controls the timer operation. It has two parts: Timer 0 and Timer 1. For each timer, you can set the timer mode by using the bits of the register. It means you can set the timer to work in one of the four modes: mode 0, mode 1, mode 2, or mode 3.The timer control register (TCON) is used to start or stop the timer, to select the timer, and to generate interrupts when the timer value reaches the specified value.
3. Difference between interval timer and event counterInterval timers are used to measure time intervals, while event counters are used to count the number of events that occur in a specific amount of time.The main difference between interval timers and event counters is that interval timers are triggered by an external signal or command, whereas event counters are triggered by the detection of a specific event.
4. Timer OverflowTimer overflow is an event that occurs when the timer count exceeds its maximum value. The microcontroller detects this event by checking the timer overflow flag (TOV).When the timer overflows, the overflow flag (TOV) is set to 1. This indicates that the timer has reached its maximum count value and has wrapped around to 0. To clear the overflow flag, the microcontroller needs to read the timer register and perform some operation to reset the timer value.

Therefore, full pitch is 36 / 8 = 4.5 slotsPitch of the short-pitched winding is 4.5 – 2 = 2.5 slotsDistribution Factor, Kd = cos(π / 8) / sin(2π / 36) = 0.9708 / 0.315 = 3.0803Overlapping Factor, Ko = 2 / π × cos⁻¹(2 / 2.5) = 1.143Pitch Factor, Kp = 3.0803 / 1.143 = 2.694Main Answer:The pitch factor of a 4-pole alternator having 36 slots is short-pitched by 2 slots is 2.694.Explanation:Given the data, we have calculated the pitch factor of a 4-pole alternator having 36 slots is short-pitched by 2 slots. The formula used to calculate the pitch factor is Pitch Factor, Kp = Distribution factor (Kd) / Overlapping factor (Ko)
.The number of coils in a 4-pole alternator is calculated by multiplying the number of poles by two, which is 8 in this case. To obtain a full pitch, divide the total number of slots, 36, by the number of coils, 8. Therefore, the full pitch is 4.5 slots, and the pitch of the short-pitched winding is 4.5 – 2 = 2.5 slots.The formula for the distribution factor (Kd) is cos(π / 8) / sin(2π / 36) = 0.9708 / 0.315 = 3.0803. The formula for the overlapping factor (Ko) is 2 / π × cos⁻¹(2 / 2.5) = 1.143.Finally, the pitch factor (Kp) is determined by dividing the distribution factor (Kd) by the overlapping factor (Ko). Therefore, the pitch factor for the given data is 2.694.

A company has issued 10 year bonds with face value of Php 1,000,000 in 1000 units. Interest at
16 % is paid quarterly. If an investor desires to earn 20 % annual interest on Php 100,000 worth of
those bonds. What would the price of bond have to be?
The price of the bond would have to be approximately Php 899,650.25.
Given:
Face value of the bond (FV) = Php 1,000,000
Number of units = 1000
Interest rate = 16% per annum
Desired annual interest on Php 100,000 worth of bonds = 20%
Step 1: Convert the annual interest rate to the quarterly interest rate:
Quarterly interest rate = (1 + annual interest rate)^(1/4) - 1
= (1 + 0.20)^(1/4) - 1
≈ 0.0474 or 4.74%
Step 2: Calculate the quarterly interest payment:
Quarterly interest payment = Face value of the bond × Quarterly interest rate
= Php 1,000,000 × 0.0474
= Php 47,400
Step 3: Calculate the number of quarters in 10 years:
Number of quarters = 10 years × 4 quarters/year
= 40 quarters
Step 4: Calculate the price of the bond:
Price of the bond = (Quarterly interest payment × [1 - (1 + Quarterly interest rate)^(-Number of quarters)]) / Quarterly interest rate + (Face value of the bond / (1 + Quarterly interest rate)^Number of quarters)
= (Php 47,400 × [1 - (1 + 0.0474)^(-40)]) / 0.0474 + (Php 1,000,000 / (1 + 0.0474)^40)
≈ Php 899,650.25
Therefore, the price of the bond would have to be approximately Php 899,650.25.

A point charge of 6nc is located at origion find the potentional potentional of point (0.2, -0.4, 0). (b) Two point changes of - Sne and 2ne are at (19/11) and (-1,0, -1) find the potentional at (0.51,-2) V = 3/²0²2 - 30'z Determine E and I at located (0) if 1 2¹ (3,7/6, 2) = {2/6 is the angle in radian)
(a) Let V be the electric potential of the point P, (0.2, −0.4, 0) caused by a point charge of 6nC located at the origin. The electric potential at point P is given by the formula V = kQ/r where k is the Coulomb constant k = 9 × 109 Nm²/C²Q is the charge in Coulombs, r is the distance between the point charge and point P measured in meters.
Therefore, the electric potential V at point P isV = kQ/r = 9 × 109 Nm²/C² × 6 × 10⁻⁹ C/√(0.2² + (-0.4)² + 0²) m= 9 × 109 Nm²/C² × 6 × 10⁻⁹ C/0.44 m= 122.7272727 V≈ 122.73 V(b) Let V be the electric potential of point P, (0.51, -2), caused by two point charges of -5nC and 2nC located at (19/11, 0, -1) and (-1, 0, -1) respectively. The electric potential at point P is given by the formula V = kQ1/r1 + kQ2/r2where k is the Coulomb constant k = 9 × 109 Nm²/C²Q1 and Q2 are the charges in Coulombsr1 and r2 are the distances between the point charges and point P measured in meters.
Then we have Q1 = -5 × 10⁻⁹ C, r1 = √[(0.51 - 19/11)² + (-2 - 0)² + (-1 - 0)²] m= 4.265425 mQ2 = 2 × 10⁻⁹ C, r2 = √[(0.51 + 1)² + (-2 - 0)² + (-1 - 0)²] m= 2.5121727 m Therefore, V = kQ1/r1 + kQ2/r2= 9 × 10⁹ Nm²/C² (-5 × 10⁻⁹ C/4.265425 m + 2 × 10⁻⁹ C/2.5121727 m)= -5.39829947 V + 7.17106035 V= 1.77276088 V≈ 1.77 V(c) Given thatV = 3/²0²2 - 30'zSinceV = -dV/dz, we haveE = -dV/dz = d/dz(3/²0²2 - 30'z)= 0 - 30= -30 V/m Also, since E = -dV/dr, we haveI = -dV/dr = d/dx(3/²0²2 - 30'z)= 0Therefore, E = -30 V/m and I = 0 at point (0).The correct option is;E = -30 V/m and I = 0 at point (0).

Create a python script that will perform the following actions on MongoDB:
1. Export the "shipwrecks" collection from the "sample_geospacial" database in your Atlas cluster to a csv file. This collection is imported when you import test data into your Atlas Cluster.
2. Import the csv file into your local Mongo instance. Put the records in the database "project_scripts" and collection "shipwrecks".
3. Remove all records where the depth field is less than 10. You can do this before you import the data or after.
4. Allow importing and exporting to be performed independently via command line arguments. It is acceptable if your script does nothing if no options are specified.
5. Remove some records before importing and some after. For example remove all records from the DataFrame that have a depth less than 5 before importing the data, then remove all records with a depth less than 10 from the collection.
Python script that will perform the actions mentioned above, we need to make use of the PyMongo driver that enables us to easily interact with MongoDB.
We will also be using the Pandas library to read and manipulate CSV files. The following are the steps to perform the actions mentioned above:Step 1: Install the Required LibrariesBefore we start, we need to make sure that we have the PyMongo and Pandas libraries installed. You can install them using the following commands:pip install pymongo pip install pandasStep 2: Set up a Connection to Atlas Cluster
To export the "shipwrecks" collection from the "sample_geospacial" database in your Atlas cluster to a csv file, we need to first establish a connection to the Atlas cluster using PyMongo.
