Question

A sinusoidal wave on a string is described by the equation y = (0.169 m) sin (0.713 x - 41.9 t), where x and y are in meters and t is in seconds. If the linear mass density of the string is 10.1 g/m ..

if needs values of these ( the speed of the wave is 58.77 m/s) (the wavelength 8.8123 m) (frequency 6.669 Hz)

a) ... the phase of the wave at x = 2.27 cm (0.0227 m) and t = 0.175 s. ?
b) .. the power transmitted by the wave ???? pleasee helpp
