You dive one meter below the surface of a small backyard pool, then one meter below the surface of a large lake. How do the pressures on your ears compare?

Wing lift can be explained by Bernoulli’s principle and also by Newton’s third law. What is the relationship between the two explanations?

A strong steady wind blows a trash can across a street. Is this Bernoulli’s principle at work?

A sealed balloon is taken from sea level up to an altitude where the outside pressure is half of what it was, at the same temperature. What happens to its volume?

A helium balloon released outdoors rises, expands, and eventually stops climbing. What stopped it?

A tire gauge reads zero on a completely flat tire. What does that tell you about what a gauge measures?

In a pipe that narrows, what happens to the fluid and to its streamlines?

The pressure a liquid exerts at a given point depends on which two things?

A rock of volume 0.0080 [m3] is fully submerged in fresh water. What is the buoyant force on it?

A statue weighs 250 [N] in air, and the buoyant force on it when submerged in fresh water is 100 [N]. What will a scale read while it is under water?
