Question

Which statement describes what happens when somebody slaps their hand on a wall?

Answer 1

Answer:

B. Wall applies equal reaction force on hand

Explanation:

This is newton's third law. You push something, that something pushes you back with same force. The direction is opposite, so if I push a wall, the wall pushes me back with same force just in opposite direction (so wall towards me). This is why option A is incorrect b/c it says force in same direction as wall. C and D talk about unequal force which is incorrect.
