ms to Canvas for the following problems. There should be 7 programs.
4B, 5, 6
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 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_forwardQ2/ If x from (1-10) write a program to print the summation of every two consecutive even numbers (2+4) (4+6) (6+8) ... اكتب برنامج بلغة الفورتران لطباعة مجموع كل رقمي ين زوجي ين متعاقي ي ين ل لأعداد المحصورة بين 1 إلى 10arrow_forward

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.
