Get started for freeAn object that can float in both water and in oil (whose density is less than that ofwater) experiences a buoyant force that is
(a) Greater when it is floating in oil than when floating in water.
(b) Greater when it is floating in water than when floating in oil.
(c) The same when it is floating in water or in oil.
(I) (a) Calculate the total force of the atmosphere acting on the top of a table that measures 1.7mร 2.6m. (b) What is the total force acting upward on the underside of the table?
You hold a piece of wood in one hand and a piece of iron in the other. Both pieces have the same volume, and you hold them fully under water at the same depth. At the moment you let go of them, which one experiences the greater buoyancy force?
(a) The piece of wood.
(b) The piece of iron.
(c) They experience the same buoyancy force.
(d) More information is needed.
(I) State your mass and then estimate your volume. [Hint: Because you can swim on or just under the surface of the water in a swimming pool, you have a pretty good idea of your density.
