Buoyancy and Floating Bodies Quiz

When a solid cylinder is completely immersed in a liquid and ρS > ρL, what will happen?

• The body will float
• The body will suspend in the liquid
• The body will sink to the bottom
• The body will partially emerge

What determines the buoyant force acting on an object?

• Object's shape
• Object's color
• Volume of liquid displaced
• Object's temperature

When a ship moves from fresh water to salt water, what happens to its immersed volume?

• Increases
• Decreases
• Remains constant
• Becomes zero

If the weight of a body is equal to the buoyant force, what is the body's state?

• Sinking
• Floating
• Suspended
• Rising

The buoyant force depends primarily on:

• Liquid's density
• Object's density
• Gravitational acceleration
• Object's volume

When ρS < ρL, a body will:

• Sink completely
• Float partially
• Suspend in liquid
• Rise to surface

The loss in weight of different bodies with equal volumes in the same liquid will be:

• Different
• Zero
• Same
• Proportional to density

A balloon's rising force is calculated by:

• Buoyant force + balloon weight
• Buoyant force - balloon weight
• Balloon weight × gravity
• Liquid density × volume

When a body is completely immersed in a liquid and ρS = ρL, it will:

• Sink
• Float
• Suspend
• Rise

The buoyant force of air on a balloon is calculated as:

• ρair × g × Volume
• Mass × gravity
• Density × height
• Weight × acceleration
