What is no work force? The force exerted by the person is an upward force equal to the weight of the box, and that force is perpendicular to the motion. If there is no motion in the direction of the force, then no work is done by that force. What is no work force give […]
What is a disadvantage of using solar energy?
What is a disadvantage of using solar energy? High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so […]

What happens when you reverse the current in a coil?
What happens when you reverse the current in a coil? When a coil drains a charged capacitor, the flow of charge in the coil does not stop, and the coil will “charge up” the capacitor again, but with reversed voltage. The voltage across the capacitor reverses, and the energy flow reverses, yet the direction of […]
