Question

In the equation of velocity of sound $V=\sqrt{\frac{\gamma P}{p}}$ obtain the dimension of $\gamma$, where $P$ and $\rho$ represent pressure and density respectively.

Answer 1

The dimension of $\gamma$, where $P$ and $\rho$ represent pressure and density will be $\left[ M ^{0} L ^{0} T ^{0}\right]$.
