Answer 1

A component gives effective value of a vector in a particular direction.
For example when a block placed on an inclined plane, the component of wieght
perpendicular to plane is mg cos alpha and the component along the plane is

mg cos (90-alpha) equal to mg sin alpha

Answer 2

hey!
the answer is,

A component give effective value of a vector in a particular direction.
