Also, the forces must be in vector form. For this part of the lab, you must develop a script that does the following: 1. Require the user to input a position vector, then the corresponding force, until there are no more forces in the system. You can have the user type in 0 to stop the script from asking for more. 2. Utilize the cross command to calculate the cross product 3. Use the fprintf command to out the Moment in cartesian, vector form. Meaning you have to have the unit base vectors i, j, & k and the proper units. 4. The program can take in any position vectors and corresponding forces. 5. Hint: The 150 N force is directed in the negative direction and its vector is: F₁ = -150k N. The position of this force is r₁ = 21 m 6. Hint: The 200 N force is directed in the positive y direction and its vector is: F₂ = 200j N. The position of this force is r₂ = 2.5i-2j m

The grayscale2 function is already written, you just need to write inside it how to convert an image to grayscale using the crude average of RGB: from images import Image def grayscale1(image): """Converts an image to grayscale using the psychologically accurate transformations.""" for y inrange(image.getHeight()): for x inrange(image.getWidth()): (r, g, b) = image.getPixel(x, y) r = int(r * 0.299) g = int(g * 0.587) b = int(b * 0.114) lum = r + g + b image.setPixel(x, y, (lum, lum, lum)) def grayscale2(image): """Converts an image to grayscale using the crude average of the r, g, and b""" pass def main(): filename = input("Enter the image file name: ") image = Image(filename) grayscale2(image) image.draw() if __name__ == "__main__": main()
Create a vector x which ranges in values from -180 to 180 in steps of 10. Then let y = x. These values are in degrees. Find a variable z = cosd(x)’*sind(y); Use surf to plot the surface plot, and label using commands xlabel, ylabel, and zlabel. Add a title.

code To count the number of people who enter your store, you could use the same motiondetection feature and count the number of files generated. The only problem is youmight run out of space. To get over this problem it is possible to write a short programthat maintains the number of pictures in a spreadsheet by date and then deletes thepictures.
The following program rotates a cube with mouse clicks. In the display callback, the Lookat function is used to point the viewer, whose location can be altered by the x, X, y, Y, z and Z keys. The perspective view is set in the reshape callback.

Create a new javascript file called cart.js and make a product object for each of your products and store it in a products array when the script loads. Create an empty array to store the items added to the cart. Program the "add to cart button" to take the product id, finds the product object in the products array and adds it to the items added to cart array. Program the "remove from cart button" to take the product id and remove the project object from the items purchased array. Existing code: <!DOCTYPE html><html> <head> <div id="product1" class="card"><img src="img/clorox.jpg"><h1>Clorox</h1><p class="price">$20.00</p><p>Household Cleaner</p><p><button id="product1Btn1">Add to Cart</button></p><p><button id="product1Btn2">Remove from Cart</button></p></div> <div id="product2" class="card"><img src="img/oxiclean.jpg"><h1>Oxiclean</h1><p…
Build on our PBM image creator from (code shown below) to create a fully functional image editor (in C++), using 2D arrays to store our changes. To make it more interesting by switching to the Portable Gray Map standard. 8 bit PGM files have color values ranging from 0 (black) to 255 (white), with the values in-between being shades of gray. The header is very similar to PBM, and looks like this: P2 WIDTH HEIGHT 255 IMAGE_DATA The P2 tells image readers that it is a PGM file, and the 255 indicates the largest possible color value is 255. You will first prompt the user to enter a width, height, and initial color value to fill the image. You should then create a 2D array with those dimensions and initialize each cell with that color value. You will then use a loop to create a menu that repeatedly prompts the user to make one of the following choices: Fill in a pixel with a new color ◦ Prompt the user to enter a row and column value and a new color value. If the array has that row and…

Another functionality for the app is the ability to estimate the return on investment over a period of time. In order to implement this feature, you will have to update the investment calculator algorithm. The base function to calculate the return on investment from Task 1 can be reutilized here to simplify our task. This feature will take into consideration a 12-month period by default. To calculate the total amount earned over a period of time, you will have to loop through the n-months period, increase the amount for each period. The other rules from the previous task apply here as well. For example: If you invest $3 million on the first month, and obtain a return of $93,000 dollars, then the amount to be invested in the second month is $3.093 million. To summarize: Loop over a period of 12 months to calculate the total for each period Return the accumulated estimated value for a period of 12 months
