Lifeguards love to spin their whistles. describe this motion and explain it using angular momentum terminology. also, use complete sentences.

Explanation:

The angular momentum is defined as the product of the moment of inertia of the body and the angular velocity of the object.

In the given problem, Lifeguards love to spin their whistles. The person spins the whistle about  fixed axis by using his fingers.

In this case, the whistle is moving about the fixed axis with the angular velocity. Then there will be angular momentum.

In order to prevent an energy crisis, it is also crucial that we consume less energy by improving and modernising energy infrastructure such as smart grid solutions, and smart cities. It is also important that we replace old devices by energy efficient solutions, such as replacing traditional light bulbs by LEDs
