Explanation:
someone to check if the answer is correct
All transverse waves can be polarized. this is because these waves oscillate at 90 degrees to the direction of energy movement.
These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

Note that by the law of inertia, it's the nature of objects to continually be in motion. For something to be still, there has to be a presence of a force.
They mention "no outside forces" so you know that a kid isn't kicking the object or a train is hitting it, or anything like that. Still, there are internal forces working, and I drew it out for you :) Hope this helps!
