Question

John rings a doorbell.

Answer 1

Answer:

Yes

Explanation:

Remember, Newton's third law of motion; which says in part that "Every action has an equal and opposite reaction."

Hence, in this case, the fact that the doorbell rang out implies that there was another force that was exerted on it; which is, John's finger pressing the doorbell.

In other words, when John uses his fingers to press the doorbell button he applies a force (a mechanical force), and that force results in an opposite reaction; the ringing of the doorbell.
