• Not enough information to solve

Why is the top of an airplane wing curved?

• To create an area of low pressure above the wing

• To create an area of high pressure above the wing

• To create equal pressure above and below the wing

• To make the wing look really cool

What is the formula for density?

• density = m/v

• density = mv

• density = v/m

• density = m+v

A person weights 800N, and they displace 200 N of water when in a swimming pool. Their weight while in the water (their apparent weight) is:

• 600N

• 800N

• 200N

• 0N

If an object weighs 100N, and its Fbuoy is 20 N, the weight of the displaced water is:

• 100 N

• 20 N

• 80 N

• none of these answers

If an object displaces less water than its weight (Fbuoy < Fg), the object will

• float

• accelerate

• create friction

• sink
