Question

One property Q of a material is used to describe the behaviour of sound waves in the material.Q is defined as the pressure P of the sound wave divided by the speed v of the wave and the surface area A of the material through which the wave travels:

Q=P/vA

Answer 1

$\frac{kg \cdot m^{-2}}{m \cdot s^{-1} \cdot m^{2}} = kg \cdot s \cdot m^{-5}$
