12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.
