Assertion: The length of the glass tube in air column resonating experiment is 75 cm. If velocity of sound in air is 330ms^(-1) , The experiment connot be performed with a tuning fork o frequency n=482 Hz.

A car is moving with a speed of 72 km-hour^(-1) towards a roadside source that enits sound at a frequency of 850 Hz. The car driver listens to the sound while approching the source and again while moving away from the source after crossing it.

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is
