A car is travelling at `(V)/(10) ms^(-1)` and sounds horn of frequency 990 Hz. The apparent frequency heard by a police chasing the car at `(V)/(9) ms^(-1)` where V is velocity of sound

A car is moving towards a stationary wall making Horn of frequency 400 Hz. The reflected frequency heard by a driver of car is 500 Hz.Find the speed of car. [v= speed of sound]

A car is moving towards a high cliff. The car driver sounds a horn of frequency f . The reflected sound heard by the driver has a frequency 2 f . if v be the velocity of sound, then the velocity of the car, in the same velocity units, will be
