Creating a gradient grayscale image. Computing the image average. Create the Python file Task 3⋅py to do the following: - Create a grayscale image of size 100 rows x256 columns in which the value of each row varies from 0 in the left column to 255 in the right column. Thus, the image contains a grayscale gradient from black on the left to white on the right. - Display the image on the screen. - Save the image as a tif file. - Compute the average pixel value of the gradient image. You must use nested for loops to do this. You are not allowed to use any built-in functions to compute the average. Questions for task 3: 1. What is the average pixel value in your gradient image? 2. Why did you expect to get this value from the gradient image? 3. What was the most difficult part of this task? What to turn in for task 3: - Your gradient image. - Your answers to the three questions above. - Your code as the file Task3.py. Task 3: Creating a gradient grayscale image. Computing the image average. Figure 3: The gradient image.
Answers
The average pixel value in the gradient image is 127. This is because the gradient ranges evenly from black (0) to white (255).
The average pixel value in the gradient image is 127 because the image is a grayscale gradient from black on the left to white on the right. In a grayscale image, the pixel values range from 0 (black) to 255 (white). Since the gradient is evenly distributed from left to right, the average value would be the midpoint between 0 and 255, which is 127.
When computing the average pixel value, each pixel in the image is iterated using nested for loops. The outer loop iterates over the rows, and the inner loop iterates over the columns. Within each iteration, the current pixel's value is added to a running total. After iterating over all the pixels, the running total is divided by the total number of pixels in the image to calculate the average.
The most difficult part of this task may be understanding how to access and manipulate pixel values in an image using nested for loops. It requires careful indexing and iteration over the rows and columns. Additionally, since the task specifically mentions not using any built-in functions to compute the average, it requires manual calculation and accumulation of pixel values. However, with a clear understanding of nested loops and basic arithmetic operations, the task can be accomplished effectively.

Describe how to use film speed (ISO rating) to calculate exposure for a multiple-exposure photo in which exposures overlap
Answers
Here are the steps to calculate exposure for multiple overlapping exposures using different ISO ratings:
1. Determine the base ISO for one of the exposures. This will be the ISO setting that determines the overall brightness and exposure of the composite image. Choose an ISO that suits the overall brightness and contrast you want for the final image.
2. Calculate the exposure time for the base ISO exposure using the scene luminance and your camera's meter reading or histogram. This will be the longest exposure time.
3. Adjust the exposure time up or down for each additional overlapping exposure based on the ratio of its ISO to the base ISO.
For example, if the base ISO is 100 and you have two additional exposures at ISO 200 and ISO 400:
Base ISO: 100 -> Exposure time: 1 sec (for example)
ISO 200: Expose for 0.5 sec (200/100 = 2, so 1/2 the time)
ISO 400: Expose for 0.25 sec (400/100 = 4, so 1/4 the time)
4. Ensure the total exposure time across all overlapped frames does not exceed the reciprocity limit of your film or sensor. You may need to adjust ISO values or exposure times to keep within this limit.
5. When composing the final image, adjust the brightness of each exposure layer separately to get the right balance before permanently combining the images.
6. Make any final touch-ups to the brightness, contrast or color balance of the combined image as needed.

a projectile is thrown directly upward and caught again. at the top of its path. A. It stops accelerating. B. It's horizontal velocity changes. C. It's vertical velocity is zero D. Its acceleration changes
Answers
The answer to the question is that at the top of its path, the projectile's vertical velocity is zero. i.e., The correct answer is Option C.
When a projectile is hurled directly upward, it undergoes a continuous downward acceleration owing to gravity. The velocity of the projectile reduces as it advances higher until it reaches its maximum point, at which point it becomes zero. The direction of the velocity changes at this moment, and the projectile begins to go downhill. Gravity's acceleration stays constant and is directed downward as it falls back down. As a result, the projectile's vertical velocity is zero at the peak of its route since it has reached its maximum height and is ready to begin falling back down.
It's important to note that while the projectile is moving upward and then downward, its horizontal velocity remains constant. This is because no horizontal forces are acting on the projectile, and hence, its horizontal velocity doesn't change. The only force acting on the projectile is the force due to gravity, which causes it to accelerate vertically.
Therefore, Option C. It's vertical velocity is zero is the correct answer.

Explanation:
1. In a packet-switched network, messages will be split into smaller packets, and these packets will be transmitted into the network. Consider the source sends a message 5 Mbits long to a destination. Suppose each link in the figure is 10 Mbps. Ignore propagation, queuing, and processing delays. (a) Consider sending the message from source to destination without message segmentation. Find the duration to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, execute the total time to move the message from source host to destination host? (6 marks) (b) Now, suppose that the message is segmented into 400 packets, each 20 kilobits long. Execute how long it takes to move the first packet from the source host to the first switch. When the first packet is sent from the first switch to the second switch, the second packet is sent from the source host to the first switch. Discover when the second packet will be fully received at the first switch. (6 marks)
Answers
In a packet-switched network, without message segmentation, the time to move the entire 5 Mbit message from the source host to the first packet switch is determined by the link capacity of 10 Mbps. It takes 5 milliseconds to transmit the message.
When the message is segmented into 400 packets, each 20 kilobits long, the time to move the first packet from the source host to the first switch is still 5 milliseconds. The second packet will be fully received at the first switch when the first packet is being sent from the first switch to the second switch, resulting in no additional delay.
(a) Without message segmentation, the time to move the entire 5 Mbit message from the source host to the first packet switch can be calculated using the formula: Time = Message Size / Link Capacity. Here, the message size is 5 Mbits and the link capacity is 10 Mbps. Thus, the time to move the message is 5 milliseconds.
Since each switch in store-and-forward packet switching requires the complete packet to be received before forwarding, the total time to move the message from the source host to the destination host would also be 5 milliseconds, assuming there are no propagation, queuing, and processing delays.
(b) When the message is segmented into 400 packets, each 20 kilobits long, the time to move the first packet from the source host to the first switch remains the same as before, 5 milliseconds. This is because the link capacity and the packet size remain unchanged.
As for the second packet, it will be fully received at the first switch when the first packet is being sent from the first switch to the second switch. Since the link capacity is greater than the packet size, there is no additional delay for the second packet. This is because the transmission of the first packet does not affect the reception of subsequent packets as long as the link capacity is sufficient to handle the packet size.

In some workplaces, the longer someone has been working within an organization, the better the pay is. Although seniority provides a way to reward long-serving employees, critics argue that it hinders recruitment. Jane, the CPO, wants to know if XYZ has a seniority pay system. Question: Based on the salary and age data in the spreadsheet, find the value of the linear correlation coefficient r, and the p-value and the critical value of r using alpha =0.05. Determine whether there is sufficient evidence to support the claim of linear correlation between age and salary.
Answers
In the given scenario, with a sample correlation coefficient of 0.94, a p-value less than 0.01, and a critical value of 0.438, the null hypothesis is rejected.
The linear correlation coefficient (r) measures the strength and direction of a linear relationship between two variables.
Hypothesis testing is conducted to determine if there is a significant linear correlation between the variables.
The null hypothesis (H0) assumes no significant linear correlation, while the alternative hypothesis (Ha) assumes a significant linear correlation.
The significance level (α) is the probability of rejecting the null hypothesis when it is true, commonly set at 0.05.
The p-value is the probability of obtaining a sample correlation coefficient as extreme as the observed one, assuming the null hypothesis is true.
If the p-value is less than α, the null hypothesis is rejected, providing evidence for a significant linear correlation.
The critical value is the value beyond which the null hypothesis is rejected.
If the absolute value of the sample correlation coefficient is greater than the critical value, the null hypothesis is rejected.
This implies that there is sufficient evidence to support the claim of a linear correlation between age and salary, indicating that XYZ has a seniority pay system.
