The Speed of Sound in Gases

When traveling through a gas, the speed of sound depends primarily on the density of the medium. The less dense the medium, the faster the speed will be. The following table shows the approximate speed of sound at O degrees Celsius, measured in meters per second, when traveling through carbon dioxide, air, helium, and hydrogen.

Medium Speed (meters per sec)
Carbon dioxide 258.0
Air 331.5
Helium 972.0
Hydrogen 1270.0

Write a program that displays a menu allowing the user to select one of these four gases. After a valid selection has been made, the program should ask the user to enter the number of seconds (0 to 30) it took for the sound to travel in this medium from its source to the location at which it was detected. The program should then report how far away (in meters) the source of the sound was from the detection location.

Input Validation: If the use enters an invalid menu choice the program should display an error message instead of prompting for the number of seconds.

Summary During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W: W = 35.74 + 0.6215 × T - 35.75 × V0.16 + 0.4275 × T × V0.16 where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. Instructions Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.
The Harris-Benedict equation estimates the number of calories your body needs to maintainyour weight if you do no exercise. This is called your basal metabolic rate, or BMR.The formula for the calories needed for a woman to maintain her weight isBMR = 655 + (4.3 x weight in pounds) + (4.7 x height in inches) -(4.7 x age in years)The formula for the calories needed for a man to maintain his weight isBMR = 66 + (6.3 x weight in pounds) + (12.9 x height in inches) -(6.8 x age in years)A typical chocolate bar will contain around 230 calories. Write a program that allows the userto input his or her weight in pounds, height in inches, age in years, and the character M formale and F for female. The program should then output the number of chocolate bars thatshould be consumed to maintain one's weight for the appropriate sex of the specified weight,height, and age.
