As opposed to a vector, a scalar has a single number. In physics, this is used in situations where a single number is enough to describe something.
Force is not a SCALAR because it always has a DIRECTION, making it a VECTOR. A SCALAR quantity is a one-dimensional physical quantity, i.e. one that can be described by a single real number.
The significance of the divergence of a scalar times a vector in vector calculus is that it simplifies to the scalar multiplied by the divergence of the vector. This property is important in understanding how scalar fields interact with vector fields and helps in analyzing the flow and behavior of physical quantities in various fields of science and engineering.
It's a vector one.

No, mass is not a scalar quantity. It is a scalar quantity. Scalars have only magnitude and no direction.

Plane angle is a scalar quantity because it only has magnitude (in units of radians or degrees), and no direction associated with it. It represents the amount of rotation needed to bring one ray to coincide with the other.
