One end of a 9. 00-m wire vibrates sinusoidally, creating a wave that travels in the positive \(x\) direction. The wave has a frequency of \(60.0 \mathrm{~Hz}\), a wavelength of \(3.00 \mathrm{~m}\), and an amplitude of \(0.0725 \mathrm{~m}\).

(a) Write the time-dependent wave function that describes this wave.

(b) If the mass of the wire is \(1.20 \times 10^{-2} \mathrm{~kg}\), what is the power supplied to the wire to create this wave?
