Question

question 17 of 25 which of the following describes an action - reaction pair? a. a cup pushes down on a table, and the table pushes down on the ground. b. you sit on a chair, and the chair is pulled down by gravity. c. the moons gravity pulls on earth, and your gravity pulls on the moon. d. you push on a wall, and the wall pushes back on you.

Explanation:

According to Newton's third - law, for every action, there is an equal and opposite reaction. In option D, when you push on a wall (action), the wall pushes back on you (reaction). In option A, the table pushing down on the ground is not the reaction to the cup pushing on the table. In option B, the chair being pulled down by gravity is not a reaction to sitting on it. In option C, the gravitational pull between the Moon and Earth is a different gravitational interaction and not related to your gravity pulling on the Moon in the context of an action - reaction pair.

Answer:

D. You push on a wall, and the wall pushes back on you.
