Question

Khimraj · Answer

Let n 1 = frequency of police car horn heard by observer n 2 = frequency of stationary source heard by observer v = velocity of bicycle Then n 1 = [(330-v)/(300-22)]*176 n 2 = [(330+v)/(300)]*165 n 1 – n 2 = 0 Sov = 22m/s. Hope it clears. If you like answer then please approve it.
