The air inside a balloon exerts a force of 1.5 n on an area of 0.5 m^2. what is the pressure inside the balloon?

Lesson 9: Fluid Pressure (connexus students!)

1.D) 3 n/m^2

2.C) 2 meters below the surface of a swimming pool

3.B) cork

4.A) depends only on the type of fluid

5.A) the air pressure decreases

it is called kinetic energy

no. dot product   =0 when vecs at right angles
