What else can I help you with?
What kind of quantity is speed an example of?
Speed is an example of a scalar quantity, as it only has magnitude (numerical value) without a specific direction.
Is scalar quantiy is added with vector quantity?
No, a scalar quantity cannot be added to a vector quantity directly. They belong to different types of quantities - scalars have only magnitude while vectors have both magnitude and direction. To add a scalar to a vector, you would need to convert the scalar to a vector by giving it a direction and then perform vector addition.
What cannot be a scalar quantity?
A scalar quantity is something that only has magnitude and no direction. Any physical quantity that has both magnitude and direction, such as velocity or force, cannot be a scalar quantity.
Is radius a scalar?
Yes. A scalar is a physical quantity that does not depend on direction. For example, temperature is a scalar because it has no directional value. Velocity is not a scalar (it is a vector quantity) because it has direction.
Is mass is scalar?
No, mass is not a scalar quantity. It is a scalar quantity. Scalars have only magnitude and no direction.
