you push on a wall with 20 n of force to the right. you feel the wall pushing back on you with a force of ______ n leftwards (take the left direction as positive).

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 action force is 20 N to the right, so the reaction force (wall pushing back) is equal in magnitude, 20 N, and opposite in direction (leftwards, which is defined as positive here).

Answer:

20
