(C) The general equation for a wave is $y = a \sin(2 \pi n t)$,where $n$ is the frequency.For the first wave,$y_1 = a \sin(2000 \pi t)$,we have $2 \pi n_1 = 2000 \pi$,which gives $n_1 = 1000 	ext{ Hz}$.For the second wave,$y_2 = a \sin(2008 \pi t)$,we have $2 \pi n_2 = 2008 \pi$,which gives $n_2 = 1004 	ext{ Hz}$.The number of beats heard per second is equal to the difference in frequencies: $|n_2 - n_1|$.Number of beats $= 1004 - 1000 = 4 	ext{ beats per second}$.

Beats are produced by two waves given by $y_1 = a \sin(2000 \pi t)$ and $y_2 = a \sin(2008 \pi t)$. The number of beats heard per second is
