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

If you could explain how you got the answers and the logic thatwould be awesome and I'll award you the points! Thank you!

A. what will be the speed of these waves if we triple M withoutstretching the wire?

B. what will be the speed of these waves if we replace the wirewith an identical one, except twice as long?

c. What will be the speed of these waves if we replace the wirewith one of the same length, but two times as heavy

D. what will be the speed of these waves if we stretch the wireto thrice its original length

E. What will be the speed of these waves (in terms of V) if weincrease M by a factor of 18.0, which stretches the wire to doubleits origina length?
