A stretched string has a mass per unit length of 4.60 g/cm and a tension of 18.0 N. A sinusoidal wave on this string has an amplitude of 0.123 mm and a frequency of 56.1 Hz and is traveling in the negative direction of an x axis. If the wave equation is of the form y(x,t) = Ym sin(kx + wt), what are (a) ym, (b) k, and (c) w, and (d) the correct choice of sign in front of w? (a) Number 0.123 Units mm (b) Number i 0.563 Units rad/m or m^-1 (c) Number 352 Units rad/s or s^-1 >
