When tensile stress is applied axially on circular rod its: (0) diameter decreases (il) length increases (ili) diameter increases (iv) length decreases 1. a) only i only li 8. b) c) ill & iv & il theselastic e) none of these

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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

hope that                                         : )

magnified images possible images can be real = projected onto a screen

momentum of soft ball three times less than baskey ball
