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)

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
