Acopper weight weighs 268 n in air and displaces an amount of water weighing 30. n . what is the weight of the copper measured in water?

238 N

Explanation:

Archimedes principle states that every body submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body:

Here, is the immersed weight of the copper, and is the weight of the displaced water. Due to this, the copper has a weight when immersed in water of:

answer; ///(74) degrees is your answer..

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
