Textbook Problem

Your hands are wet, and the restroom towel dispenser is empty. What do you do to get drops of water off your hands? How does the motion of the drops exemplify one of Newton’s laws? Which one?

To determine

The reason due to which the drop of water gets off from person’s hand and the Newton’s law applicable here.

Explanation of Solution

The Newton’s first law of motion states that, a body remains in motion until unless some external force is not opposing it, or the body will remain in rest until unless some external force is not applied on it to cause it in motion.

In the given proven the person will shake his hands, to gets the drops off from his hand. This follows the Newton’s 1st Law, as the drops are initially at rest, when ...
