A conveyor belt moves to the right with speed v = 300 m/ min . A pieman puts pies on the belt at a 30 m /min towards a receiver at the other end. The frequency with which they are received by the stationary receiver is

A conveyor belt moves to the right with speed v=300 m/min. A pieman puts pies on the belt at a rate of 20 per minute while walking with speed 30 m/min towards a receiver at the other end. The frequency with which they are received by the stationary receiver is

A conveyor belt moves to the right with speed upsilon = 300 m//s . A very fast pieman puts pies on the belt at a rate of 20 per minute and they are recived at the other end by a pieeater. (a) If the pieman is stationary find the spacing x betweenthe pies and the frequency with which they are recived by the stationary pieeater. (b) the pieman now walks with speed 30 n//min towards the reciver while continuing to put pies on the recived by the stationary pieeater.

A conveyor belt is moving horizontally with a uniform velocity of 2 m/sec. Material is dropped at one end at the rate of 5 kg/sec and discharged at the other end. Neglecting the friction, the power required to move the belt is-

A radio receiver is designed to receive transmissions at 20m, 25m and 30 m bands. Calculate the range of frequencies to which the receiver can be tuned.

A rocket is going towards moon with a speed v . The astronaut in the rocket sends signals of frequency v towards the moon and receives them back on reflection from the moon. What will be the frequency of the signal received by the astronaut (Take v lt lt c )

A source S of acoustic wave of the frequency v_0=1700Hz and a receiver R are located at the same point. At the instant t=0 , the source start from rest to move away from the receiver with a constant acceleration omega . The velocity of sound in air is v=340(m)/(s) . Q. If omega=10(m)/(s^2) , the apparent frequency that will be recorded by the stationary receiver at t=10s will be
