Acircular hole in an aluminum plate is 2.739 cm in diameter at 0.000°c. what is the change in its diameter when the temperature of the plate is raised to 108.0°c? cm

Explanation:

As we know that thermal expansion coefficient of aluminium is given as

now we also know that after thermal expansion the final length is given as

here we know that

now we will have

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
