An aeroplane is going towrds east at a speed of `510 kmh^-1` at a height of2000 m. At a certain instant, the sound o theh plane heard by a ground obserger appears to come from a point vertically above him. Where is the plane at this instant? Speed of sound in air `=340 ms^-1`

An aero plane is going towards east at a speed of 510 kmh^-1 at a height of 2000 m. At a certain instant, the sound o the plane heard by a ground observer appears to come from a point vertically above him. Where is the plane at this instant? Speed of sound in air =340 ms^-1

A train approaching a railway crossing at a speed of 120 km/h sounds a whistle of frequency 576 Hz, when it is 288 m away from the crossing . The frequency heard by the observer standing on the road perpendicular to the track from the crossing at a distance of 384 m is (Speed of sound in air = 340 ms^(-1) )

A source and a detector move away from each other, each with a speed of 10 ms^-1 with respect to the ground with no wind. If the detector detects a frequency 1950 Hz of the sound coming from the source, what is the original frequency of the source? Speed of sound in air =340 ms^-1 .

A source and a detector move away from each other, each with a speed of 10 ms^-1 with respect to the ground with no wind. If the detector detects a frequency 1950 Hz of the sound coming from the source, what is the original frequency of the source? Speed of sound in air =340 ms^-1 .

A source emitting sound at frequency 4000 Hz, is moving along the Y-axis with a speed of 22 m s^-1 . A listener is situated on the ground at the position (660 m, 0). Find the frequency of the sound received by the listener at the instant the source crosses the origin. Speed of sound in air = 330 m s^-1 .
