C) electrons

A magnet is useful in generating electricity because a magnetic force moves electrons

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
