The air leaves the balloon in one direction; the car moves in the opposite direction. this balloon car illustrates for action, there is an equal and opposite reaction or a) the law of gravity. b) newton's 1st law of motion. c) newton's 2nd law of motion. d) newton's 3rd law of motion.

Option (D) is the correct answer.

Explanation:

Newton's third law of motion states that when one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

Therefore, when car is moving in forward direction then air in balloon leaves in opposite direction.

Thus, we can conclude that this balloon car illustrates for action, there is an equal and opposite reaction or Newton's 3rd law of motion.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
