• floats

• neutrally buyant

Which properties affect buoyancy?

(select all that apply)

• Mass

What is buoyant force?

• An upward force exerted by fluids on an object.
• An downward force exerted by fluids on an object.

Density is the relationship between which two quantities?

• Mass and volume

• Mass and weight

• Volume and weight

A brick weighs the most in.......

• air

• water

• space

According to the table: what would a block of gold do in gasoline?

• Sink

• Float

• remain in place

This is the relationship between area and pressure 

• As area increases, the pressure increases
• As area increases, the pressure decreases.
• As area decreases, the pressure decreases
• They have no effect on each other

How does the diameter of a column (depth) of water affect the pressure at the bottom of the column?

• No effect
• The pressure decreases
• The pressure increases
• It depend upon the length of the diameter.

The buoyant force on an object equals 50 N. What is the weight of the displaced water?

• 50 N

• 50 lbs

• 50 N/9.8 m/sec²

• not enough information given
