VPython 3500) assignments/3090165 Answers to 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.

String - Practice Questions Write a python program using strings to read input from the user and count the character a. Write a python program using strings to read two input and convert the first input to lowercase and second input to uppercase. Write a python program using strings to read input from the use and replace all the character a with z. Write a python program using strings to read input from the user and find the length of the string.

Trigonometry: The basic MATLAB trigonometric functions are sin, cos, tan, cot, sec, and csc. The inverses, e.g., arcsin, arctan, etc., are cal- culated with asin, atan, etc. The same is true for hyperbolic functions. The inverse function at an2 takes two arguments, y and x, and gives the four- quadrant inverse tangent. The argument of these functions must be in radians. Calculate the following quantities: sin, cost, and tan. sin²+ cos². (Typing sin^2(x) for sin²x will produce an error). y cosh²z-sinh² x, with x = 32m.

Key stroke enacted moving of a ball 1. Start (a) Write a Java program that uses the Up, ↑, Down ↓, Right → (and possibly Left) arrows of the keyboard (or keypad) to move a ball. (note the Up arrow is called “Up" with ASCII code 38, Down arrow is called "Down" with ASCII code 40, Right arrow is called "Right" with ASCII code. You can also use the 4 keys, commonly used in ODS game programming. Start Pond Figure 1. Initially Pond End End Start Pond Start Figure 2. After 3 moves up using up arrow End Pond End Figure 3. 3 moves later with right arrows Figure 4. Finally one at the lower right corner. (b) Using Java class JFrame to draw a grid of 5 horizontal lines, 5 vertical lines, a blue pond in the middle occupying 5 squares with a text Pond in the middle, a ball at the lower left corner, and texts called Start and End. This is shown exactly as in Figure 1 here. Change the color of ball from green to another color.

Q5\A) The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent. The equations of the carrier signal, the original signal to send, and the modulated signal combining the two signals are respectively: VI-V sin (2nfet) V2=Vm sin (2πfmt) V3-V sin (2nfet)+ Vm sin (2nfmt)* sin (2πfet) Supposing that Vc =Vm=1, fc-20, fm-1. Write a MATLAB program that plots the three signals with single call, the graphs must be contain (desired title, axis labels, annotations, with symbols for color, style, and marker) for each graph. Use the step 0.0025 for the time.

2. Characters in Strings A large part of the text processing done by computers involves reading user input and figuring out what it means. We'll do something like that today: given a string supplied by a user, we report (1) the total length of the string, (2) how many alphabetic characters, (3) how many numeric characters, (4) how many vowels (a, e, i, o, u) were in that string, and (5) how many of the alphabetics were upper-case. For example, if a user input this line: the program would say: String length: 30 James Bond, 007, works for MI6 Alphabetics: 19, upper-case: 4 Numerics: 4 Vowels: 6 You will need to use a new (to us) function to read the user input. You have been using cin but this won't work for your needs in this program. Instead, use getline (cin,s) where s is a string variable. That string will contain everything the user typed up to but not including the Enter the user typed to end the line. So you have a string but you'll need a loop to check for each individual…
