A longitudinal standing wave `xi a cos kx. Cos omega t ` is maintained in a homogeneous medium of density `rho`. Find the expressions for the space density of  `(a)` potential energy `w_(p)(x,t),`  `(b)` kinetic energy `w_(k)(x,t),`  Plot the space density distribution of the total energy `w` in the space between the displacement nodes at the moments `t=0` and `t=T//4`, where `T` is oscillation period.
