A vector is parallel to the y axis, what is it x component?

Explanation:

A vector is parallel to the y axis .

Let its magnitude be A . So the vector can be represented as A j .

where i and j are unit vectors in x and y axis direction .

The x component of A j will be dot product of A j with i

The x component of A j = A j . i

= A x 0      [  Since j . i = 0 ]

= 0

porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
