A heavy chain of length `1 m` and weight `20 kg` hangs vertically with one end attached to a peg and carries a block of mass `10 kg` at the other end. Find the work done in winding `50 cm` of chain round the peg.

A uniform rope of length 10 cm and mass 4 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?

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?

A uniform rope of length 10 m and mass 15 kg hangs vertically from a rigid support. A block of mass 5 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.08 m is produced at the lower end of the 3 rope. The wavelength of the pulse when it reaches the top of the rope will be-

A light string passes over a pulley. To one of it's ends 6 kg is attached. To the other end a mass of 10 kg attached. The tension in the string will be
