Question

a balloon is inflated and then released as shown below. when the balloon is released, air is pushed out by the balloon. which other force is acting that demonstrates newtons third law of motion? a. the air is pushing back on the balloon in the opposite direction. b. gravity is helping to move the balloon in the same direction. c. the weight of the balloon pushes it in the opposite direction. d. the air is pushing back on the balloon in the same direction.

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. Here, the action is the balloon pushing air out; the reaction is the air exerting an equal force back on the balloon in the opposite direction, which makes the balloon move. Options B, C, and D do not align with this law: gravity/weight acts downward (not the direction of balloon movement), and the reaction force must be opposite to the action.

Answer:

A. The air is pushing back on the balloon in the opposite direction.
