Question

14. The speed of sound in a medium is v=1400 m/sec, and it's density is rho=100 kg/m. Based on this information, what should the bulk modulus be for this material? (Pa=kg/(m*sec^2)) A. 1,960,000,000 Pa B. 196,000,000 Pa C. 37,416.574 Pa D. 3741.657 Pa

Answer 1

Bulk modulus is a measure of how much pressure , or force ,is needed to change the amount of volume in a material

The bulk modulus of this material is given by the equation

B=P/V
In this case the bulk modulus is 3741.667 Pa, which answer is D.
