An observer while going on scooter hears sound of two sirens of same frequencies from two opposite directions. If he travels along the direction of one of the siren, then he

The two waves of the same frequency moving in opposite direction give rise to

A person going away from a factory on his scooter at a speed of 36 km/hr listens to the siren of the factory. If the frequency of siren is 525 Hz and a wind is blowing along the direction of scooter at 36km/hr the frequency, heard by the person is (velocity of sound = 340 m/s)

Two protons are travelling along the same straight path but in opposite directions. The relative velocity between the two is

Two cars get closer by 8 m every second while traveling in the opposite directions. They get closer by 0.8 m while traveling in the same directions. What are the speeds of the two cars ?

A person going away from a factory on his scooter at a speed of 36 km/hr listens to the siren of the factory. If the actual frequency of the siren is 700 Hz and a wind is blowing along the direction of the scooter at 36 km//hr, find the observed frequency heard by the person. (Given speed of sound = 340 m//s )
