A piano wire is stretched to a tension of 330 N. A wire is just a
string made of metal. If the wire is 1.76 m long and has a total
mass of 0.250 kg, what is the phase speed of transverse waves
travelling along this wire?
Linear mass density is
u = m/L =0.25/1.76
u =0.142 kg/m

A horizontal wire is stretched with a tension of 94.0 N , and the speed of transverse waves for the wire is 406 m/s. What must the amplitude of a traveling wave of frequency 73.0 Hz be in order for the average power carried by the wave to be 0.360 W ?
3. [1pt] Consider the phase speed of transverse waves on a wire, with the changes listed below. Answer `true' (T), `false' (F), or `cannot tell' (C) to each of the five statements. E.g., if the answer to the first statement is T and to the rest, F, enter TFFFF. If the tension in the wire is doubled, the phase speed of the transverse wave doubles. If the tension is increased and the mass of the wire is decreased (assuming the...
