1. A. Write a VPython program that creates eight spheres, each placed at one corner of a cube
centered on the origin. The length of a side of the cube should be 6 units, and the radius of each
sphere should be 0.5. Use at least two different colors for the spheres.
B. Add to the program an arrow whose tail is at one corner of the cube and whose tip is at the
corner diagonally opposite. The figure below shows the display from one possible solution to
this problem.
2. Write a VPython program that represents the x, y, and z axes by three cylinders of different
colors. This display from one possible solution is below.
The area of a pentagon can be computed using the following formula (s is the length of a side):
Area = ( 5 * s2 ) / ( 4 * tan( π/5 )
Write a program that prompts the user to enter the side of a pentagon and displays the area.

Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

The program must identify all resistors in series or in parallel with each other and calculate the equivalent resistance for each group of resistors. Recall that total resistance of resistors in series are added up while the total conductance of those in parallel are added up. Input Format: The first line of the input consists of 1 integer N which is the total number of resistors. The next N lines will consist of 3 strings and an integer R each separated by a space. The first string is the resistor name, the second and third strings are the node names where the resistor terminals are connected, and R is its resistance value. Output Format: One line for each group of resistors in series or parallel. Each line starts with a list of resistors arranged in lexicographical order (see Lexicographic order - Wikipedia) followed by their total resistance rounded off to the nearest…arrow_forward
