A police car moving at 22m//s , chases a motorcyclist, the police man sounds his horn at 176 Hz , while both of them move towards a stationary siren of frequency 165 H z. Calculate the speed of the motorcycle, if it is given that he does not observes any beat

A police car moving at 22 ms^(-1) chases a motor cyclist. The police man sounds horn at 176 Hz. While both of them move towards a stationary siren of frequency 165 Hz. If the number of beats heard by the motor cyclist per second is zero, then the speed of motorcycle is (Speed of sound in air = 330 ms^(-1) )

A police car moving at "30 m s"^(-1) , chases a motorcyclist. The policeman sounds his horn at 180 Hz, while both of them move towards a stationary siren of frequency 160 HZ. He does not observe any beats then, calculate the speed ("in m s"^(-1)) of the motorcyclist round off two decimal places? [speed of sound =330ms^(-1) ]

Two tuning forks with natural frequencies 340 H_(Z) each move relative to a stationary observer . One forks moves away from the oberver while the other moves towards him at the same speed . The observer hears beats of frequency 3 H_(Z) . Find the speed the of the tuning fork (velocity of sound in air is 340 m//s) .

The ratio of the apparent frequencies of a car when approaching and receding a stationary observer is 11:9 What is the speed of the car, if the velocity of sound in air is 330 m/s?

a bus is moving towards and stationary observer with speed 20 m/s blows a horn of frequency 200 Hz. the frequency of sound heard by the observer is approximately ( take speed of sound 320 m/s)

Bus moving with speed v forwards a stationary wall. it produces sound of frequency f = 420 Hz. The heard frequency of reflected sound from wall by driver is 490 Hz . Calculate the speed v of bus. The velocity of sound in air is 330 m/s .

A person is riding a motorcycle at a speed v towards a stationary car operating its siren at 165Hz. A police car is chasing the person at a speed 22 m/s with its siren operating at 176 Hz. If the motorcyclist does not heard beats, the speed v (m/s) is (speed of sound in air = 330 m/s)

A whistle giving out 450 H_(Z) approaches a stationary observer at a speed of 33 m//s . The frequency heard the observer (in H_(Z) ) is (speed of sound = 330 m//s )

A whistle giving out 450 H_(Z) approaches a stationary observer at a speed of 33 m//s . The frequency heard the observer (in H_(Z) ) is (speed of sound = 330 m//s )
