How are the heating systems similar and how are they different?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

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