Which of the following wrongly defines "pressure" in physics?
The force applied perpendicular to the surface of an object per unit area over which that force is distributed.
In the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid.
The force that a liquid or gas produces when it presses against an area
The use of persuasion or intimidation to make someone do something
What is the correct formula for pressure?
The normal force applied over the area of the force exerted on
The gravitational force acting on the object
The area of the force exerted on over the force applied
The perpendicular force applied over the area of the force exerted on

Which of the following is not true about Pascal's Laws?
Pascal's Laws are the physic laws that are named in honor of Blaise Pascal
Pascal's Law #1 says that the pressure acts uniformly in all directions on a small volume of a fluid
Pascal's Law #2 says in a fluid confined by solid boundaries, pressure acts perpendicular to the boundary
Pascal's Law #3 says that for a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line
