There are two forces acting on the life jacket - its weight and the force of the water pushing ... Things that float are buoyant. If the weight is greater than the upthrust, it sinks.

and so the buoyant force should have remained the same. However, the density of the ball was changing—it increased as the ball's diameter decreased. Density is the mass per unit volume—it ...

First, we need to know a little about buoyancy. If the buoyant force of a fluid is greater than the downward force (its mass times the gravitational field strength) of an object placed within it ...

then uses its enormous buoyant force to drive water through a turbine NoviOcean says a full-size platform should operate 24/7 at a capacity factor between 40-70%, each unit generating an average ...
