What is the voltage across r2 with an input voltage of 5.0v and resistors r1 = 1.5 kiloohms and r2 = 0.5 kiloohms? calculate this value in volts.

A60-kg box is being pushed a distance of 6.8 m across the floor by a force p with arrow whose magnitude is 162 n. the force p with arrow is parallel to the displacement of the box. the coefficient of kinetic friction is 0.24. determine the work done on the box by each of the four forces that act on the box. be sure to include the proper plus or minus sign for the work done by each force. (the floor is level and horizontal. forces that act on the box: pushing force p, frictional force f, normal force n, and weight mg.)

You’re evaluating a new hire in your company’s engineering department. together you’re working on a circuit where a 0.1@μf, 50-v capacitor is in series with a 0.2@μf, 200-v capacitor. the new engineer claims you can safely put 250 v across the combination. what do you say?
