Problem 3 (NEW-HW). True or False: Two infinite parallel plates a distance L apart are filled with an incompressible fluid. The lower plate is stationary and the upper plate oscillates

in the x-direction with a frequency w and a maximum plate velocity of U , as shown in the figure below. For this situation, a natural set of characteristic length, time, and velocity scales are L,T period, and U, where T period = 2n/w.
