Soft rubber is used as a part of a motor mounting. Its adiabatic bulk modulus is Bs

Question:

Soft rubber is used as a part of a motor mounting. Its adiabatic bulk modulus is Bs = 2.82 × 106 kPa, and the volume expansivity is αp = 4.86 × 10-4 K-1. What is the speed of sound vibrations through the rubber, and what is the relative volume change for a pressure change of 1 MPa?
