Answer:

it's answer is B. Vector Quantity

hope it helps you!

Answer 2

The correct answer is (B) vector quantity.

When the axis of rotation is fixed, the angular velocity is considered as a vector quantity.

Angular velocity is defined as the rate of change of angular displacement with respect to time.

It is a vector quantity because it has both magnitude and direction.

The magnitude of the angular velocity is given by the rotational speed or the angular speed, while the direction is determined by the right-hand rule.

A scalar quantity is a physical quantity that has simply magnitude and no direction.

Such physical quantities can be described solely by their numerical value.

These physical quantities are added using basic algebraic rules, and just their magnitudes are added here.

Physical quantities, usually referred to as base quantities, are those that can be measured and quantified. for instance, length, weight, time, etc.

Therefore, the correct answer is (B) vector quantity.
