A point sound source is situated in a medium of dulk modulus `1.6 xx 10^(5) N//m^(2)`. An observer standing at a distance `10 m `from the source writes down the equeation for the wave as `y = A sin (15 pi x - 6000 pi t)`. Here `y` and `x` are in meter and `t` is in second. The maximum pressure ampulitude received to the observer's ear is `(24 pi)` pa, then find.  (a) the density of the medium,  (b) the displacement ampulitude `A` of the wave recived by the observer and  (c ) the power of the sound source.
