The screen size of a TV is given by the length of the rectangular diagonal. Traditional TVs come in 4:3 ratio, that is, the ratio of length to width is 4 to 3. This means, if the length is x inches, then the width is (3/4)x. LCD TVs come in 16:9 ratio. Write a program that prompts the user to input the length of the diagonal (in inches) of the screen and allows the user to select which type of TV’s screen length, screen width, and screen area the user would like to calculate. Have the program display the desired results.
Write a program that computes the cost of painting and installing carpet in aroom. Assume that the room has one door, two windows, and one bookshelf. Your program must do the following:a. Prompts the user to enter, in feet, the length, width, and height of aroom. Read the dimensions of the room.b. Prompts the user to enter the widths and heights, in feet, of the door,each window, and the bookshelf. Read these quantities.c. Prompts the user to enter the cost, per square foot, of painting thewalls. Read these quantities.d. Prompts the user to enter of cost, per square foot, of installing carpet.Read these quantities.
A mass m is attached to the end of a rope of length r 3 meters. The rope can only be whirled
around at speeds of 1, 10, 20, or 40 meters per second. The rope can with stand a maximum tension
of T = 60 Newtons.
Write a program where the user enters the value of the mass m, and the program determines the
greatest speed at which it can be whirled without breaking the rope.
Assume that the mass m is less than 100 kg.
Hint: T = mv2 /r.
Drop Your Code here:
#Set the rope length
#Set the maximum tension
#Set the message
#Read the mass value
#Set a list of possible rotation speed
#Set the size of the list
Drag your statements from the following choices:
length = 3
max_tension = 60
message = "The greatest speed without breaking the rope is:"
mass = float(input(">>>Enters the value of the mass m: "))
rotation_speed - [1. 10, 20, 40]
N= len(rotation_speed)

- An oil slick occurs when an underwater refinery pipe ruptures, pumping oil into the water. The spilled oil sits on top of the water and causes a natural disaster. For simplicity, suppose that the oil sits on top of the water in the form of a circle. Write a program that prompts the user to enter the rate at which the ruptured pipe pumps oil (in gallons) per minute, the thickness of the oil on top of the water, and the number of days for which the area is covered by the spilled oil. The program outputs the spilled area (in kilometer) and the volume of oil (in gallons) on top of the water after each day.arrow_forwardAn oil slick occurs when an underwater refinery pipe ruptures, pumping oil into the water.

The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify the amount of premixed concrete (in cubic yards) ordered, the thickness of the patio (in inches), and the ratio of length and width. The program then outputs the length and width of the patio (in feet). (1 cubic yard 5 27 cubic feet.) (To find the square root of a decimal number, include the header file cmath using the statement #include <cmath>, in your program. The function sqrt, included in this header file, determines the square root of a decimal number.

Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forward
