The diagram shows a trace of a wave on a cathode-ray oscilloscope. the vertical and horizontal gridlines have a spacing of 1.0cm. the voltage scaling is 4vcm–1 and the time scaling is 5ms cm–1. 1cm1cmwhat are the amplitude and period of the wave? amplitude/v period/ ms a 1.5 4 b 5.0 10 c 6.0 20 d 12.0 20

a is the correct answer dear

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.

explanation:

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
