Answer:
Step-by-step explanation:
The scenario of rock climbers pulling their vertical rope downward to push themselves upwards is an example of Newton's Third Law of Motion.
Newton's Third Law of Motion states: "For every action, there is an equal and opposite reaction."
In the context of the rock climbers' situation, the action is the force they exert on the rope by pulling it downward. According to Newton's Third Law, there will be an equal and opposite reaction force. This reaction force is exerted by the rope on the climbers, pushing them upward. As a result, the climbers can use this upward reaction force to propel themselves upwards, aiding in their ascent.
