a) Obtain Laplace's formula for velocity of sound in air starting from Newton's formula.
b) A car producing note of frequency \( 500\text{Hz} \) approaches and passes a stationary observer at the steady speed of \( 20\text{ms}^{-1} \). Calculate change of frequency heard by the observer (Velocity of sound = \( 340\text{ms}^{-1} \)).
