Chapter 1, Problem 8MCP

The speed of a sound wave traveling in a medium that has bulk modulus B and mass density ρ (mass divided by the volume) is $\nu =\sqrt{\frac{B}{\rho }}$. What are the units of the bulk modulus in SI base units?

1. A.    $\frac{\text{kg}\cdot \text{m}}{{\text{s}}^2}$
2. B.     $\frac{\text{kg}}{{\text{m}}^2\cdot \text{s}}$
3. C.     $\frac{\text{kg}}{\text{m}\cdot {\text{s}}^{\text{2}}}$
4. D.    $\frac{\text{kg}}{\text{m}\cdot \text{s}}$
