pushed away‚ or repelled‚ each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel

A Porter’s Five Forces Analysis explores five principal industry factors to determine the attractive of a given industry in a given market. In this P5F exercise‚ we look at the automobile industry in India. This is independent of any manufacturer. As such‚ it applies to every Indian car manufacturer. In any P5F analysis‚ one must examine the following: 1. The threat of new entrants 2. The bargaining power of buyers/customers 3. The threat of substitute products 4. The amount of bargaining

I recently read an article on The Atlantic‚ “Lincoln and his Great Depression‚” and was struck by how the author ended his article: "Lincoln didn’t do great work because he solved the problem of his melancholy; the problem of his melancholy was all the more fuel for the fire of his great work.” I am not the type of person who quotes others in essays‚ but I am also not the type of person who has a sickness openly discussed in public.

In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a
