When a mass M hangs from a vertical wire of length L, waves travel on this wire

Question

When a mass M hangs from a vertical wire of length L, waves travel on this wire with a speed V.

Part A What will be the speed of these waves (in terms of V) if we double M without stretching the wire? V1 =____

Part B What will be the speed of these waves (in terms of V) if we replace the wire with an identical one, except twice as long? V2 =_____

Part C What will be the speed of these waves (in terms of V) if we replace the wire with one of the same length, but three times as heavy? V3 =______

Part D What will be the speed of these waves (in terms of V) if we stretch the wire to twice its original length? V4 =_____

Part E What will be the speed of these waves (in terms of V) if we increase M by a factor of 10.0, which stretches the wire to double its original length? V5 =_____

Explanation / Answer

A. V1 = V*sqrt(2)

B. V2 = V

C. V3 = V / sqrt (3)

D. V4 = V*sqrt(2)

E. V5 = V(2)sqrt(5)
