A string of mass 2.50 kg is under a tension of 200 N. The length of the stretched string is 20.0 m. If the transverse jerk is struck at one end of the string, how long does the disturbance take to reach the other end ?

A steel wire 0.72 m long has a mass of 5.0 xx 10^(-3) kg . If the wire is under a tension of 60 N. What is the speed of transverse waves on the wire ?

A uniform rope of length 12 mm and mass 6 kg hangs vertically from a rigid support. A block of mass 2 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.06 m is produced at the lower end of the rope. What is the wavelength of the pulse when it reaches the top of the rope?

One end of a taut string of length 3m along the x-axis is fixed at x = 0 . The speed of the waves in the string is 100ms^(-1) . The other end of the string is vibrating in the y-direction so that stationary waves are set up in the string. The possible wavelength (s) of these sationary waves is (are)

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. If the speed of sound in air is 320m//s , find the tension in the string.

A steel wire 0.72 m long has a mass of 5.0 xx 10 ^(-3) kg. If the wire is under a tension of 60 N, what is the speed of transvers waves on the wire ?

A stone is tied to an elastic string of negligible mass and spring constant k. The unstretched length of the string is L and has negligible mass. The other end of the string is fixed to a nail at a point P. Initially the stone is at the same level as the point P. The stone is dropped vertically from point P. (a) Find the distance 'y' from the top when the mass comes to rest for an instant, for the first time. (b) What is the maximum velocity attained by the stone in this drop ? (c) What shall be the nature of the motion after the stone has reached its lowest point ?

A string of mass per unit length mu is clamped at both ends such that one end of the string is at x = 0 and the other is at x =l . When string vibrates in fundamental mode, amplitude of the midpoint O of the string is a, tension in a, tension in the string is T and amplitude of vibration is A. Find the total oscillation energy stored in the string.

A string of length 0.4 m and mass 10^(-2) kg is clamped at one end . The tension in the string is 1.6 N . The identical wave pulses are generated at the free end after regular interval of time , Delta t . The minimum value of Delta t , so that a constructive interference takes place between successive pulses is
