An engine driver moving towards a wall with velocity of 50 ms^(-1) emits a note of frequnecy 1.2 kHz . The frequency of note after reflection from the wall as heard by the engine driver when speed of sound in air is 350 ms^(-1) is :

An engine driver moving towards a wall with a velocity of 60 m/s emits a note of 1400 Hz. Speed of sound in air is 340 m/s .The frequency of the note after reflection from the wall as heard by the engine driver is

A bus is moving towards a gauge wall with a velocity of 5m//s^(-1) . The driver sounds a horn of frequency 200 Hz . The frequency of the beats heard by a passenger of the bus will be ………… Hz (Speed of sound in air = 342m//s^(-1))

A bat flies perpendicularly towards a wall with a speed of 6 m/s, emitting sound of frequency 450 kHz. What is the frequency of the wave reflected from the wall that it will hear? Given c=340(m)/(s) ?

A car is moving towards a fixed wall, it blows form of frequency of 440 Hz . The frequency of reflected sound observed by the driver is 480 Hz then find the speed of car in km/hr. (Speed of sound is 350 m/sec

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 motor car blowing a horn of frequency 124vib//sec moves with a velocity 72km//hr towards a tall wall. The frequency of the reflectedf sound heard by the driver will be (velocity of sound in air is 330 m//s )
