A person going away from a factory on his scooter at a speedof `36 kmh^-1` listens to the siren of the factory. If the main frequency of the siren is 600 hz and a wind is blowing alongthe direction of the scooter at `36 kmh^-1`, find the main frequency as heard by the person.

A person going away from a factory on his scooter at a speed of 36 km/hr listens to the siren of the factory. If the actual frequency of the siren is 700 Hz and a wind is blowing along the direction of the scooter at 36 km//hr, find the observed frequency heard by the person. (Given speed of sound = 340 m//s )

A person going away from a factory on his scooter at a speed of 36 km/hr listens to the siren of the factory. If the frequency of siren is 525 Hz and a wind is blowing along the direction of scooter at 36km/hr the frequency, heard by the person is (velocity of sound = 340 m/s)

A person standing on a road sends a sound signal to the driver of a car going away from him at a speed of 72 km h^-1. The signal travelling at 330 m s^-1 in air and having a frequency of 1600 Hz gets reflected from the body of the car and returns. Find the frequency of the reflected signal as heard by the person.

A train approaching a hill at a speed of 60 km//hour sounds a whistle of frequency 600Hz when it is distance of 1km from the hill. Wind is blowing in the direction of the train with a speed of 60 km//h Find the frequency of the whistle heard by an observer on the hill:speed of sound in air 1200km/h)

A siren is fitted on a car going towards a vertical wall at a speed of 36 kmh^(-1) . A person standing on the ground behind the car, listeners to the siren sound coming directly from the source as well as that coming after reflection from the wall. Calculate the apparant frequencies of both the sounds. Velocity of sound 340ms^(-1) , frequency of the siren 500Hz.

A train approaching a hill at a speed of 36 kmph sounds a whistle of frequency 500 Hz when it is at a distance of 1 km. A wind blows at 36 kmph in the direction of the motion of the train. Find (i) the frequency of the whistle as heard by an observer on the hill, (ii) the distance from the hill at which the echo from the hill is heard by the driver and its frequency. Velocity of sound = 1200 kmph

A train approaching a hill at a speed of 40 km//hr sounds a whistle of frequency 580 Hz when it is at a distance of 1km from a hill. A wind with a speed of 40km//hr is blowing in the direction of motion of the train Find (i) the frequency of the whistle as heard by an observer on the hill, (ii) the distance from the hill at which the echo from the hill is heard by the driver and its frequency. (Velocity of sound in air = 1, 200 km//hr )
