Question

the action force is the balloon pushing the air out. what is the magnitude of the reaction force of the air pushing on the balloon? \boxed{} n. $f_{balloon} = -3\\ n$ (with an image of a blue balloon and a force diagram)

Explanation:

Step1: Recall Newton's Third Law

Newton's third law states that for every action, there is an equal and opposite reaction. So the magnitude of the action force and reaction force are equal.

Step2: Determine the reaction force magnitude

The action force (balloon pushing air) has a related force \( F_{\text{balloon}} = - 3\space N \). By Newton's third law, the reaction force (air pushing balloon) will have a magnitude equal to the magnitude of the action - related force. The magnitude of \( - 3\space N \) is \( 3\space N \).

Answer:

\( 3 \)
