A sinusoidal wave on a string is described by the equation y $=(0\mathrm{.}149$ m$)$ sin $(0\mathrm{.}731$ x $-43\mathrm{.}1$ t$),$ where x and y are in meters and t is in seconds. If the linear mass density of the string is $10\mathrm{.}7$ g$/$m $...$

a$)...$ determine the phase constant.

$$Tries $0/99$

b$)...$ the phase of the wave at x $=2\mathrm{.}49$ cm and t $=0\mathrm{.}151$ s$.$

$$Tries $0/99$

c$)...$ the speed of the wave.

$$Tries $0/99$

d$)...$ the wavelength.

$$Tries $0/99$

e$)...$ the frequency.

$$Tries $0/99$

f$)...$ the power transmitted by the wave.
