1 hertz is equal to __________ vibration(s) per minute.
A magnet, freely suspended in a vibration magnetometer makes 40 oscillations per minute at a place A and 20 oscillations per minute at B.If BH at B is 36×10−6 T, then its value at A is :
The frequency of a source of sound is 100Hertz. How many times does it vibrate in a minute?
a body is vibrating 6000 times in a minute .if the velocity of sound in air is 360 m/s, find frequency of vibration in hertz and wavelength of the wave produced.
