A small steel wire of diameter 1.2 mm is connected to an oscillator and is under a tension of 7.6 N . The frequency of the oscillator is 65.0 Hzand it is observed that the amplitude of the wave on the steel wire is 0.44 cm .
Part A
What is the power output of the oscillator, assuming that the wave is not reflected back?
Express your answer using two significant figures
P = W
Part B
If the power output stays constant but the frequency is doubled, what is the amplitude of the wave?
