Three masses are in a swimming pool filled with water (density 1000 kg/m). All three objects are identical in size (400 cm) but have different densities. Object A floats on the water (density 580 kg/m3), Object B is completely submerged underwater but has a density equal to that of water, and Object C sinks to the bottom (density 3700 kg/m?).
Compare the magnitude of the buoyant force on each block:
a. Fa = FB = Fc
b. FA c. FA >FB = Fc
d. Fa e. FA > FB > Fc

Respuesta :

Answer:

FA < FB = FC

Explanation:

The buoyant force is equal to the weight of the displaced water.

The two that sink displace the same amount of water and therefore have the same buoyant force. The one that floats displaces less than its full volume of water and therefore has a lower buoyant force. Its buoyant force will equal its weight.
