Buoyancy and Fluid Mechanics Quiz

When a body's weight is greater than the buoyant force, what happens?

• The body floats
• The body sinks
• The body remains suspended
• The body partially submerges

What occurs when a body's weight exactly equals the buoyant force?

• The body sinks
• The body floats
• The body is suspended in the liquid
• The body rises to the surface

When a body's weight is less than the buoyant force, what happens?

• The body sinks
• The body remains stationary
• The body moves upwards
• The body compresses

What determines the buoyant force acting on a body?

• Only the body's density
• The volume of liquid displaced
• The body's weight
• The liquid's temperature

When a ship moves from fresh water to salt water, what changes?

• Buoyant force remains constant
• Buoyant force increases
• Buoyant force decreases
• Ship's total weight changes

If different bodies of equal volume are immersed in the same liquid, what happens to their weight loss?

• Varies randomly
• Remains different
• Becomes zero
• Remains the same

What is the relationship between a body's weight and the weight of displaced liquid when floating?

• They are unrelated
• Weight of body equals weight of displaced liquid
• Weight of body is half the displaced liquid
• Weight of body is double the displaced liquid

When a body is suspended in two immiscible liquids, what remains constant?

• Total volume
• Liquid density
• Weight of body
• Total force

What happens to a balloon's rising force?

• Always constant
• Depends on air temperature
• Equals buoyant force minus balloon weight
• Increases with altitude

In a hollow body suspended in a liquid, what relationship exists between forces?

• Weight equals buoyant force
• Buoyant force exceeds weight
• Weight exceeds buoyant force
• No relationship exists
