If an object floats, the volume of the displaced water is equal to the volume of the portion of the object that's above the surface of the water. true or false

FALSE

Explanation:

When object float in water then it means that weight of the object is counterbalanced by the buoyancy force.

Here as we know that buoyancy force is the weight of water displaced by the object.

So here when object is submerged into the water then the submerged part of the volume of object will displace exactly the same volume of water and that volume of water will exert upwards buoyancy force on the object.

So here this statement is not true as it says that volume of water displaced is volume above the surface of water while it must be like volume of water displaced must be equal to volume of submerged part of the object.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
