Power
A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is done, that is, will t..

Electricity is produced by converting the potential energy of water (from a height) into the kinetic energy of flowing water. Hydroelectricity or hydroelectric power is produced, when large quantities of water stored in dams at a suitable height, are released to fall from a height. A dyn..

Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric power consumed P..

Resolving Power - The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identified. Resolving power..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
It's help ful session. I translate my book with him it was great time - William
She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Encouraging resource, great material to help students with studies. Really helpful... - Paul
