multiple choice question
how does air push an airboat forward?
the airboat pushes the air backward, and the air exerts an opposing force forward on the airboat.
the air pushed backward by the boat exerts a balanced force on the airboat.
as air moves around the airboat, air resistance exerts a forward force on the airboat.

Explanation:

This is based on Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. The airboat's propeller pushes air backward (action), and the air exerts an equal forward force on the airboat (reaction) to move it forward. Balanced forces would not cause motion, and air resistance acts against motion, not forward.

Answer:

The airboat pushes the air backward, and the air exerts an opposing force forward on the airboat.
