Question

A student inflates a balloon attached to a plastic straw. A string is threaded through the straw and tied to opposite ends of the room. When the air in the balloon is released, the balloon travels the length of the string.

Answer 1

It obeys Newton's third law of motion.

Step-by-step explanation:

The experiment obeys Newton's third law of motion because when the air in the balloon is released, the air moves in the downward direction which is an action of the balloon so in the reaction, the balloon moves in upward direction so both action and reaction forces are equal in magnitude but moves in opposite direction which obeys Newton's third law of motion.
