A tuning fork in air vibrates at 30 Hz with 5 cm amplitude. If the velocity of sound in air is 330 `ms^-1`, derive the expression for the generated travelling wave.

A tuning fork un air vibrates at 30 Hz with 5 cm amplitude . If the velocity of sound in air is 330 m.s ^(-1) , derive the expression for the generated travelling wave .

A car moving at a velocity of 17 ms^(-1) towards an approaching bus that blows a horn at a frequency of 640Hz on a straight track. The frequency of this horn appears to be 680 Hz to the car driver. If the velocity of sound in air is 340ms^(-1) , then the velocity of the approaching bus is

A 50 cm long pipe, open at both ends, produces resonant vibration with a tuning fork. If the velocity of sound in air is 350 m*s^(-1) , what is the frequency of the tuning fork ?

The length of a pipe, open at one end is 30 cm . If the velocity of sound in air is 330 m*s^(-1) , find out the fundamental frequency and the frequencies of the first two overtones formed due to vibration of the air column in the pipe .

A wire of length 25 cm and mass 2 . 5 g is stretched with a fixed tension. The length of a pipe closed at one end is 40 cm . During vibrations, the first overtone of the wire produces 8 beats per second with the fundamental emitted by the pipe . The number of beats reduces with the decrease in tension in the wire. If the velocity of sound in air is 320 m*s^(-1) , find the tension in the wire.

At normal temperature and pressure the velocity of sound in air is 330 m/s . If the temperature increased to 30^@C and the pressure remains the same the velocity of sound in air will be

A train moving with a velocity v is passing a station. A passenger standing on the station notices that the whistle emitted by the train changes its frequency by 50 Hz when it passes him. Given that the frequency of the whistle when the train is at rest with respect to the passenger is 500 Hz and the velocity of sound in air is 330 m/sec, the velocity of the train is
