7. A violin wire has a mass of 2.02 g and length 72.5 cm. It is stretched with a tension of 23.1 N. You observed a wave with frequency 122.3 Hz and amplitude 1.3 mm travels along the wire. Calculate the average power (in watt) carried by the wave. Express your final answer in 2 decimal places. Use pi = 3.14 in this case.
