<PRE><B>Question 1135476</B>
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)?
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
{{{T =((Vs - 273)^2)/400}}}
