What is the domain and range of y=2x+4

The force will determine the acceleration.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)

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