The density of a sample of air is 1.235 kg/m3, and the bulk modulus is 1.42 · 105 N/m2.
a) Find the speed of sound in the air sample.
b) Find the temperature of the air sample. Give answer in °C. Do not enter unit.

(a) Vsound = sqrt[E/(density)]
Solve for Vsound
(b) Use the equation that relates Vsound in air to temperature.

To find the speed of sound in the air sample, we can use the formula:
Speed of sound = √(Bulk modulus / Density)
a) First, let's calculate the speed of sound in the air sample using the given density and bulk modulus.
Speed of sound = √(1.42 × 10^5 N/m^2 / 1.235 kg/m^3)
= √(1.15 × 10^5 m^2/s^2)
= 339.41 m/s
So, the speed of sound in the air sample is approximately 339.41 m/s.
b) To find the temperature of the air sample, we need additional information because the given density and bulk modulus alone are not sufficient to determine the temperature. Could you please provide any other relevant details or data?
