when a mass m hangs from a vertical wire of length l, waves travel on this wire with a speed v.
A. what will be the speed of these waves if we triple M without stretching the wire?

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

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

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

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