Question

The speed of a sound wave is affected by the temperature of the air. At 0 °C, the speed of a sound wave is 331 m/sec. The speed increases by approximately 0.6 m/sec for every degree lin Celsius) above 0; this is a reasonably accurate approximation for 0-50°C. So, our equation for the speed in terms of a temper- ature C is 3 le speed = 331+0.6 * C Write a script soundtemp that will prompt the user for a temperature in Celsius in the range from 0 to 50 inclusive, and will calculate and print the speed of sound at that temperature if the user enters a temperature in that range, or an error message if not. Here are some examples of using the script al >> soundtemp Enter a temp in the ane: C o 50: -5.7 Brror in temperature >>soundtemp Enter a temp in the range 0 to 50: 10 For a temperature of 10.0, the speed is 337.0 >> help soundtemp Calculates and prints the speed of sound given a temperature entered by the user

Explanation / Answer

prompt = 'Enter the temperature';

temp = input(prompt);

if temp >= 0 && temp <= 50

    speed = 331 + 0.6 * temp;

    fprintf('For a temperature of %f, speed is %f ', temp, speed);

else

    fprintf('Error in temperature');

end
