Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel.
Create an application that displays a set of radio buttons allowing the user to select air, water, or steel. Provide a text box to let the user enter the distance a sound wave will travel in the selected medium. Then, when the user clicks a button, the
Format the output to two decimal places.
Input validation: Do not accept distances less than 0. Always check for nonnumeric data.
Use the following test data to determine if the application is calculating properly:

Random Number Guessing GameWrite a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over.Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses. USE RAPTOR PROGRAMarrow_forward
- You’ll create both pseudocode and a flowchart to design an application that displays the following menu: Select a Planet 1. Mercury2. Venus3. Earth4. Mars5. Exit the programEnter your selection. When the user selects a planet from the menu, the program should display the following information about the planet: Mercury Average distance from the sun 57.9 million kilometers Mass 3.31 × 10^23kg Surface temperature –173 to 430 degrees Celsius Venus Average distance from the sun 108.2 million kilometers Mass 4.87 × 10^24kg Surface temperature 472 degrees Celsius Earth Average distance from the sun 149.6 million kilometers Mass 5.967 × 10^24kg Surface temperature –50 to 50 degrees Celsius Mars Average distance from the sun 227.9 million kilometers Mass 0.6424 × 10^24kg Surface temperature –140 to 20 degrees Celsiusarrow_forwardFalling Distance When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d =1/2gt2 The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time in seconds that the object has been falling. Create an application that allows the user to enter the amount of time that an object has fallen and then displays the distance that the object fell. The application should have a method named FallingDistance. The FallingDistance method should accept an object’s falling time (in seconds) as an argument. The method should return the distance in meters that the object has fallen during that time interval.arrow_forwardWrite the pseudocode for an application that will request three numbers from a user.

The company charges $20.00 per hour for labor. Create an application that allows the user to enter the square feet of wall space to be painted and the price of the paint per gallon. The program should display the following data: • The number of gallons of paint required • The hours of labor required • The cost of the paint • The labor charges • The total cost of the paint jobarrow_forwardAn online music and apps store offers all apps for 3$ each and all songs for 7$ each. The store requires members to prepay any amount of money they wish, and then download as many apps or as many songs accordingly. You are required to write a program that would ask the user for the amount that he/she will pay, then display two messages indicating: -the maximum number of apps that can be downloaded, and how much funds will remain in the account after that, if any. -the maximum number of songs that can be downloaded, the number of apps that can be downloaded after that if funds allow, and how much funds will remain in the account after that, if any. Notice the parenthesis in app(s) and song(s) in the output. For this assignment, assume that the user will always enter a valid integer value that is >= 0, and within the limit of the integer range.
