A person sits on a freely spinning lab stool that has no friction in its axle. When this person extends her arms, A) her moment of inertia increases and her rotational kinetic energy remains thesame. B) her moment of inertia increases and her rotational kinetic energy decreases. C) her moment of inertia decreases and her rotational kinetic energy decreases. D) her moment of inertia increases and her rotational kinetic energy increases. E) her moment of inertia decreases and her rotational kinetic energy increases.

B) her moment of inertia increases and her rotational kinetic energy decreases.

Explanation:Moment of Inertia is the term used to describe the rotation of an object in relationship to its own rotation,IT IS THE PRODUCT OF MASS AND THE SQUARE DISTANCE COVERED.

Moment of Inertia is also a resistance force which tend to oppose the impact of a turning force aimed at preventing its rotation about its axis. As the moment of Inertia increases her rotational kinetic energy will continue to decrease,due to the impact of the resistant or opposing force.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

iron would move it is magnetic there is a mag field around the current in the wire
