Answer 1

vector means having direction and magnitude

Answer 2

Answer:

question:-What is a vector?

Answer:-measurement or a quantity that has both size and direction

question:-Scalar product of two perpendicular vector.

Answer:-So the scalar product of two vectors which are at right-angles is always 0. We say that such vectors are perpendicular or orthogonal. The converse of this statement is also true: if we have two non-zero vectors a and b and we find that their scalar product is zero, it follows that these vectors must be perpendicular.
