The energy level of a wave is directly related to the of the wave

A. height
B. strength
C. color
D. speed
E. length

what type of charge does it have? negative

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

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch
