Problem II $(10$ Marks$)$

The displacement of air molecules in a sound wave is given by the mathematical formula $s(x,t)=2{10}^{-6}sin(92\mathrm{.}4x-3\mathrm{.}14{10}^4)$

Where $x$ is the position along the wave in meters, and $t$ is the time in second.

a$)$ What is the maximum displacement of air molecules $($in m$)?(1$ Mark$)$

b$)$ What the wavelength of the wave $($in m$)?(2$ Marks$)$

c$)$ What is the frequency of the wave $($in Hiz$)?(2$ Marks$)$

d$)$ What is the velocity of the wave $($in $\frac{m}{s})?(3$ Marks$)$

e$)$ What is the maximum velocity of the air molecules in the wave $($in m$/$s$)?(2$ Marks$)$
