Aparticle undergoes two displacements. the first has a magnitude of 550 cm and makes an angle of 160 degrees with the positive x-axis. the resultant displacement has a magnitude of 725 cm and is directed at an angle of 75 degrees to the positive x-axis. find the magnitude and direction of the second displacement.

Answer

magnitude of second vector is 871 and it makes angle of 36.019 degrees to the positive x-axis

Solution

In this question we have given  

vector 1=

and resultant =

let second vector be V=

............(1)

on comparing x and y component of both sides of equation 1

............(3)

Therefore,

divide equation 3 by equation (2)

put value of in equation (2)

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
