ANSWER-Ohm's Law
Power (watts) is calculated by multiplying _______ times _______. - CORRECT
ANSWER-Voltage and Amps
, When talking about AC voltage, positive and negative refer to the direction or current
flow. Positive voltage causes electrons to flow away from the stations and negative
voltage causes electrons to flow _____ towards the generating station. - CORRECT
ANSWER-Towards

There are two important factors to understanding atoms: - CORRECT ANSWER-1. the
law of charges states that opposites attract an likes repel.
2. the law of centrifugal force states that a spinning object will pull away from its center
