Modern NiMH rechargeable batteries of size AA have a maximum charge capacity of 2300 mAh and an emf equal to 1.20 V. A flashlight has three of these batteries connected in series. The 3.6 V bulb in the flashlight draws a current of 0.45 A. Assume that both the emf and the current do not change with time. Calculate how long the flashlight will operate using these rechargeable batteries.

What is required for an electric charge to flow through a wire? zero resistance in the wire a balance of electric potential high resistance in the wire a difference in electric potential

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
