Under certain conditions (pressure decreasing in the x direction, the upper plate fixed, and the lower plate moving to the right in the positive x direction), the laminar velocity distribution will be as shown. For such conditions, indicate whether each of the following statements is true or false:

a. The shear stress midway between the plates is zero.
b. The minimum shear stress occurs next to the moving plate.
c. The maximum shear stress occurs where the velocity is the greatest.
d. The minimum shear stress occurs where the velocity is the greatest.
