Archimedes' Principle

If an object weighing 50.0 N displaces a volume of water with a weight of 10.0 N, what is the buoyant force on the object?

• 10 N

• 60 N

• 40 N 

• 20 N 

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

• Sink

• Float 

• Expand

• Shrink

What is the volume of Object X?

• 10.0 cm³

• 15.0 cm³

• 20.0 cm³

• 25.0 cm³

What direction is the buoyant force in?

• Downward

• Left

• Right

• Upward

Looking at the image... can oak float in water? 

• Yes

• No

The buoyant force on an object equals 250 N. What is the weight of the displaced water?

• 250 N

• 250 lbs

• 250 N/9.8 m/sec²

• not enough information given

What causes the apparent weight loss of an object immersed in water?

• Gravity

• Buoyancy

• Newton's 1st law

• Newton's 2nd law

Buoyancy force equals

• weight of displaced water

• the "weight loss" of the object immersed in water

• upward force of water 

• all of these 

When a body is fully or partly immersed in a liquid, it undergoes an apparent loss in its weight due to:

• Decrease in its volume

• Decrease in the density of the body

• Upward thrust exerted by the liquid

• Decrease in its mass

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
