TO2_Archimedes Principle

What does Archimedes' principle state about the buoyant force acting on an object?

• The buoyant force is equal to the weight of the fluid displaced by the object.

• The buoyant force is greater than the weight of the object.

• The buoyant force is less than the weight of the fluid displaced by the object.

• The buoyant force is equal to the weight of the object.

What determines whether an object will float or sink in a fluid?

• The average density of the object compared to the fluid.

• The color of the object.

• The shape of the object.

• The temperature of the fluid.

How is the buoyant force mathematically expressed according to Archimedes' principle?

• F_B = w_fl

• F_B = m*g

• F_B = p*v

• F_B = d/t

What happens to an object if its specific gravity is less than one?

• It floats.

• It sinks.

• It remains suspended.

• It dissolves.

Why do objects appear to weigh less when submerged in a fluid?

• The buoyant force counteracts some of the object's weight.

• The fluid reduces the object's mass.

• The object's density decreases.

• The fluid exerts a downward force.
