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 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 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 source of frequency 150 Hz is moving in the direction of a person with a velocity of 110 m / s . The frequency heard by the person will be (speed of sound in medium = 330 m / s )

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 source of sound is travelling with a velocity of 30(m)/(s) towards a stationary observer. If actual frequency of source is 1000 Hz and the wind is blowing with velocity 20(m)/(s) in a direction at 60^@C with the direction of motion of source, then the apparent frequency heard by observer is (speed of sound is 340(m)/(s) )

A source of sound is travelling with a velocity of 30(m)/(s) towards a stationary observer. If actual frequency of source is 1000 Hz and the wind is blowing with velocity 20(m)/(s) in a direction at 60^@C with the direction of motion of source, then the apparent frequency heard by observer is (speed of sound is 340(m)/(s) )

A car moving with a velocity of 36 km/hr crosses a siren of frequency 500 Hz. The apparent frequency of the siren after passing it will be

A train producing frequency of 640 Hz is moving towards point c with speed 72 km//hr . A person is sitting 1732 m from point c as shown. Find the frequency heard by person if speed of sound is 330 m//s .
