Archimedes' principle

The upward force exerted by a liquid on an object immersed in or floating on the liquid

• pressure
• buoyant force
• normal force
• gravity

When the weight of an object is greater than the buoyant force, the object will ... 

• Sink
• Float 
• Expand
• Shrink

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

If the weight of the water displaced is the same as the weight of the object placed in the water, the object will sink.

• True
• False

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Which box has a higher density?  

• Box A
• Box B
• cannot be determined
• they are the same

True or false... "mass" is the exact same thing as "weight"?

• True
• False

What is the likely identity of a material (see Table 10–1) if a sample has a mass of 55 g when measured in air and an apparent mass of 34.6 g when submerged in water?

• Iron or steel

• Lead

• Aluminum or granite

• Gold

A 3.80-kg aluminum ball has an apparent mass of 2.10 kg when submerged in a particular liquid. The density of the liquid is:

• 2185.7 kg/m³

• 0.44 kg/m³

• 1207.9 kg/m³

• 0.81 kg/m³
