In a hydraulic lift, the large piston has five times the area as the small piston. How much extra force can the large piston exert?

Five times as much at the small piston

One tenth as much as the small piston

One fifth as much as the small piston

Fifty times as much as the small piston

Three objects of the same volume but different materials are completely submerged in water. They are zinc with a density of 7000 kg/m 3 , nickel with a density of 8900 kg/m 3 , and silver with a density of 10500 kg/m 3 . Which has the greatest buoyant force exerted on it?

They all have the same buoyant force.

It is impossible to tell without knowing the volume.
