A

`n_(1)=10n`

B

`n_(1)=0`

C

`n_(1)=0.1n`

D

`n_(1)=-0.1n`

A vehicle, with a horn of frequency n is moving with a velocity of 30 m/s in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency n + n_(1) . Then (if the sound velocity in air is 300 m/s)

A vehicle , with a horn of frequency n is moving with a velocity of 30 m//s in a direction prependicular to the straight line joining the observer and the vehicle . The observer perceives the sound to have a grequency (n + n_(1)) . If the sound velocity in air is 330 m//s , then

If a source of frequency n moving with velocity v crosses a stationary observer, then the change in the frequency of sound heard by the observer will be (velocity of sound = V)
