A source on a swing which is covering an angle `theta` from the vertical is producing a frequency `v`. The source is distant `d` from the place of support of swing. If velocity of sound is `c`, acceleration due to gravity is `g`. then the maximum and minimum frequency hearfd by a listener in froun of swing is

A

`(cv)/(sqrt(2gd-c)),(cv)/(sqrt(2gd+c))`

B

`(cv)/(sqrt(2gd(1-costheta))-c), (cv)/(sqrt(2gd(1-costheta))+c)`

C

`(cv)/(c-sqrt(2gd(1-costheta))), (cv)/(c+sqrt(2gd(1-costheta)))`

D

`(cv)/(c-sqrt(2gd(1-sintheta))), (cv)/(c+sqrt(2gd(1-sintheta)))`

A boy sitting on a swing which is moving to an angle of 30^(@) from the vertical is blowing a whistle which is of frequency 1000Hz . The whistle is 2m from the point of support of the swing. If a girl stands in front of the swing, the maximum and minimum frequencies she will hear are (velocity of sound =330m//s , g=9.8m//s^(2) )

A mass is suspended from a vertica spring which is executing SHM of frequency 5 Hz. The spring is unstretched at the highest point of oscillation. Maximum speed of the mass is (take, acceleration due to gravity, g=10m//s^(2) )

A particle is projected vertically with speed V from the surface of the earth . Maximum height attained by the particle , in term of the radius of earth R,V and g is ( V lt escape velocity , g is the acceleration due to gravity on the surface of the earth )

A source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is

The observer is moving with velocity 'v'_(0) towards the stationary source of sound and then after crossing moves away from the source with velocity 'v'_(0) . Assume that the medium through which the sound waves travel is at rest. If v is the velocity of sound and n is the frequency emitted by the source, then the difference between appearent frequencies heard by the observer is
