B)halve.
C)remain the same.

Question

Quizplus · Accepted Answer

The linear speed of the pet hamster is directly proportional to the rotational speed of the turntable. If the rotational speed is doubled, the linear speed of the pet hamster will also double. This is because the linear speed is directly proportional to the radius of the turntable and the angular velocity, which increases when the rotational speed is doubled.

If a Turntable's Rotational Speed Is Doubled, Then the Linear
