Want this question answered?
it isn't easy for one person because one person doesn't has much mass but when two people mass is added, so they can lift a heavy object
Potential energy
Yes
That depends how high you want to lift it.
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
Yes.Since water contains materials in water, diet soda will float.
Easy, to save energy
the water provides a bouyant force proportional to the volume of water displaced.

its use formula : Fa = density . gravitation . high because water can lift up an object so if an object dipped in water', mass of an object will decrease

Potential energy
[object Object]
Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.
Yes
It will cool down water temperature when by melting down AND it will lift up the water level in the aquarium
