If an inflated beach ball is
placed beneath the surface of a pool of water and released it shoots
upward, out of the water. use archimedes' principle to explain why...
Archimedes principal is: "The
upward buoyancy force is equal to the magnitude of the weight of fluid
displaced by the body". So, the upwards force on the beach ball is equal
to the weight ot the water idisplaced when pushed underwater.
Lead has a greater density than
iron, and both metals are denser than water. Is the buoyant force on a
lead object greater than, less than, or equal to the buoyant force on an
iron object of the same volume?
The two are equal because the buoyant force depends only upon the density and volume of the liquid that is displaced.
