1. Fluid mechanics is the study of

a) how fluids do work.

b) the types of fluids.

c) how fluids form.

d) classifying fluids.

2. Two solids in contact

a) exert pressure only downward.

b) exert pressure on each other.

c) exert pressure equally in all directions.

d) do not exert pressure.

Fluid mechanics deals with pressure and internal forces in the fluid. So the correct answer should be a) how fluids do work.

If you put two solids in contact, there will be a contact force created between them. Since Pressure = Force / Area, the correct answer should be b) exert pressure on each other.
