Two cars A and B approach a statinary observer from opposite sides as shown in figure. Observer hears no beats. If the frequency of the horn of the car B is 504 Hz, the frequency of horn of car A will be

Two cars A and B approach a stationary observer from opposite sides with the speed of 15m/s and 30 m/s respectively.The observer hears no beats. If the frequency of the horn of the car B is 504 Hz , the frequency of the horn of the car A will be :

Two trains A and B approach a station from opposite sides, sounding their whistles. A stationary observer on the platform hears no beats. If the velocities of A and B are 15 m/s and 30 m/s respectively and the real frequency of the whistle of B is 600 Hz, find the real frequency of the whistle of A. (Velocity of sound = 330 m/s)

A train A is travelling at a speed of 108 km hr^(-1) The train approaches another train B standing on the platform.The engine of the train B below its horn. The frequency of the horn as observed by the driver in train A is 504 Hz. The frequency of the horn of train B is (speed of sound = 330 ms ^(-1)

A toy-car, blowing its horn, is moving with a steady speed of 5 m//s, away from a wall. An observer, towards whom the toy car is moving, is able to heat 5 beats per second. If the velocity of sound in air is 340 m/s, the frequency of the horn of the toy car is close to :
