11.

What happen to rotational and translational kinetic energy when the uniform cylinder is at rest?

Both translational and rotational kinetic energy are zero.

Translational kinetic energy is maximum, while rotational kinetic energy is zero.

Both translational and rotational kinetic energy are at their peak.

Translational kinetic energy is zero, but rotational kinetic energy is maximum.

12.

Which of the following is the correct equation to calculate torque?

Torque (τ) = Force (F) + Distance (r) + θ

Torque (τ) = Force (F) / Distance (r) × cos(θ)

Torque (τ) = Distance (r) × Force (F) × θ

Torque (τ) = Force (F) × Distance (r) × sin(θ)

13.

How torque and angular acceleration is related to each other?

Torque is directly proportional to angular acceleration, given by τ = I * α.

Torque is inversely proportional to angular acceleration.

Torque equals angular acceleration divided by mass.

Torque is unrelated to angular acceleration.

14.

What is angular momentum?

Angular momentum is the rotational equivalent of linear momentum, defined as the product of an object's moment of inertia and its angular velocity.

Angular momentum is the speed of an object moving in a straight line.

Angular momentum is the energy stored in a rotating object.

Angular momentum is the force applied to an object in motion.

15.

Does angular momentum is conserved?

Angular momentum is only conserved in open systems.

Angular momentum is always increasing in a closed system.

Angular momentum can be created or destroyed.

Yes, angular momentum is conserved in a closed system.
