Write Newton's equation for the speed of a sound wave in air.

(N/A) Newton assumed that the propagation of sound through air is an isothermal process,meaning the temperature of the medium remains constant during the compression and rarefaction cycles.
According to Newton,the speed of sound $v$ in a gas is given by the formula:
$v = \sqrt{\frac{P}{\rho}}$
Where:
$P$ is the pressure of the gas.
$\rho$ is the density of the gas.
