Two cars A and B are moving towards each other with samne speed 25 m/s. wind is blowing with speed 5 m/s in the direction of motion of car A. The car A blows horn of frequency 300 Hz and the sound is reflected from car B. the wavelength of te reflected sound received by the driver of car A is (velocity of sound in air =330m/s)

A motor car blowing a horn of frequency 124 vib//s moves with a velocity 72 km//hr towards a tall wall. The frequency of the reflected sound heard by the driver will be (velocity ofsound 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 )

Two vehicles A and B are moving towards each other with same speed u = 25 m//s . They blow horns of the same frequency f = 550 Hz . Wind is blowing at speed w = 20 m//s in the direction of motion of A . The driver of vehicle A hears the sound of horn blown by vehicle B and the sound of horn of his own vehicle after reflection from the vehicle B . If difference of wavelength of both sounds received by A is (5)/(P) . Find P . Velocity of sound is = 320 m//s .

A car is moving with a constant velocity 10 m//s towards the stationary wall. The car blows a horn of frequency 320 Hz . The velocity of sound in air is 330 m//s . The beats frequency received by the observer is

The driver of a car travelling with speed 30 m/ sec towards a hill sounds a horn of frequency 600 Hz. If the velocity of sound in air is 330 m/s, the frequency of reflected sound as heard by driver is

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
