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 AWhat is the power output of the oscillator, assuming that the wave is not reflected back?Express your answer using two significant figuresP = WPart BIf the power output stays constant but the frequency is doubled, what is the amplitude of the wave?Express your answer using two significant figures
