To make the beams at a laser light show (see Exercise 6) even more visible, they are often directed into mist or smoke. Why do such particles make the beams particularly visible

what are the options.

explanation:

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

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                                         : )
