Is scalar multiplied by a vector, a vector or a scalar?

Is charge a scalar or a vector?

State with reasons , whether the following algebraic operations with scalar and vector physical quantities are meaningful : (a) adding any two scalars , (b) adding a scalar to a vector of the same dimesions , (c ) multiplying any vector by any scalar , (d) multiplying any two scalars , (e ) adding any two vectors , (f) adding a component of a vector to the same vector .

Two physical quantities, of which one is a vector and the other is a scalar, having same dimension are :

Let vec a, vec b and vec c be three vectors. Then scalar triple product [vec a, vec b, vec c]=

If [vec(a),vec(b),vec(c)] denotes the scalar triple product of the vectors vec(a),vec(b),vec(c) , then [vec(a)+vec(b),vec(b)+vec(c),vec(c)+vec(a)] is equal to

Let vec a, vec b and vec c are unit coplanar vectors then the scalar triple product [2 vec a - vec b 2 vec b - vec c 2 vec c - vec a]

Obtain the equation of a line passing through a point A with Position vector vec(a) and parallel to a vector vec(b) both in vector and cartesion form.

Say whether linear momentum is a scalar or a vector physical quantity.

State , for each of the following physical quantities , if it is a scalar or a vector : volume , mass , speed , acceleration , density , number of moles , velocity , angular frequency , displacement , angular velocity .
