Question

A stainless steel wire has density 7.93 g/cm3 and a diameter of 4.42×10−2 cm. The wire is subject to a tension of 120 N. A sinusoidal wave with frequency 261.6 Hz and amplitude 0.837 cm is traveling along the wire.

What is the average power delivered from one region to another?

Answer 1

Find the speed of wave on the wire after finding the mass per unit length and use equation for average power for wave motion on a string to find the required solution as shown below
