A string is wrapped around the rim of a wheel of moment of inertia 0.20 kg-m^2 nd radius 20 cm. The wheel is free to rotate about it axis. Initially, thewheel is t rest. The string is now pulled by a force of 20 N. Find the angular velocity of the wheel after 5.0 seconds.

The frequency of vibration (v) of a string may depend upon length (I) of the string, tension (T) in the string and mass per unit length (m) of the string. Using the method of dimensions, derive the formula for v.

Stationary waves are produced in a stretched string of length 120 c. if the string vibrats with 6 segment and if the frquency of vibration of the string is 20 Hz. Then the velocity of waves on the string is

A transverse wave is propagating along a string of length l. when string elongated by l/20 cm, velocity of wave is v. what will be its velocity when it is elongatd by l/10 ?

If the speed of sound wave in a stretched string is V and Hook law is obeyed, then the exenion in the string if the speed of sound wave will become 1.22v.

The extension in a string,obeying Hooke's law,is x.The speed of sound in the stretched string is V.If the extension in the string is increased to 1.5x ,the speed of sound will be = n times0.61V then find 'n' value?

The extension in a string, obeying Hooke's law is x . The speed of sound in the stretched string is V . If the extension in the string is increased to 2x then speed of sound will be
