If the pitch of the sound of a source appears to drop by`10%` to a moving person, then determine the velocity of motion of the person. Velocity of sound =`300ms^(-1)`.

What is the effect of pitch and loudness on the velocity of sound ?

Find the velocity of source of sound, when the frequency appears to be (i) double (ii) half the original frequency to a stationary observer. Velocity of sound = 330 ms^(-1) .

Sound moves with higher velocity if

The frequency of the sound of a car horn as recorded by an observer towards whom the car is moving differs from the frequency of the horn by 10% . Assuming the velocity of sound in air to be 330ms^(-1) , the velocity of the car is

The sound produced by a siren given by a company reaches a person on the road at a distance of 110 m in _______ s. (Velocity of sound in air is 330 ms^(-1) )

An object producing a pitch of 400 Hz flies past a stationary person. The object was moving in a straight line with a velocity of 220 m/s. The velocity of sound in air is 330 m/s. Then the frequency of sound heard by stationary person when the object is approaching him is equal to
