Question 1135476: The speed of sound is proportional to the square root of the air temperature in still air. The speed of sound is given by the formula.
Vs=20√T+273
where Vs is the speed of sound in meters/second and
T is the temperature of the air in Celsius.
a)What is the speed of sound when the temperature is - l7°C (about l°F)?
b)What is the speed of sound when the temperature is 16°C (about 61°F)?
c}What happens to the speed of sound as the temperature increases?
d) Solve the equation for T.

.

Let me answer n.n. a), b) and c) of your post.

            Why did you decide that the tutors will do YOUR JOB for you ?

            It is YOUR JOB to substitute the given values into the given formula and calculate.

            It is NOT the tutor's job, and never was.

            Than quicker you will get this idea, than sooner you will be on a right rail.

        Making calculations is students' honor duty and a privilege !

Sub the numbers and solve for V
-------------------
c}What happens to the speed of sound as the temperature increases?
think about it.

d) Solve the equation for T.
Vs=20√T+273
Vs - 273=20√T
(Vs - 273)^2 = 400T
