Answer:
The displacement shown in the diagram has a component of 3
in the xdirection and a component of 4 in the ydirection.
It could be written as a column vector. 3 and 4 are called
the components of the vector.
In elementary mathematics and physics, a vector is a geometric
object that has both a magnitude (or length) and a direction.
A vector is graphically represented by an arrow. The magnitude
of the vector is proportional to the length of the arrow and
its direction coincides with the direction of the arrow.
