Why would a rock sink while a

rubber ball would float in water?

Multiple Choice

Why is Archimedes' principle significant in understanding why objects float or sink in fluids?

• It explains why objects change color in water.

• It helps us understand the relationship between buoyant force and displaced fluid.

• It describes why fluids evaporate quickly.

• It determines the temperature at which objects float.

Compare the buoyant force and weight of a wood block and a steel block of the same size when placed in water. Why does one float and the other sink?

Multiple Choice

Which of the following statements about Pascal's principle are correct?
