If there are 745 watts for every horsepower how many horses would it take to power a single hundred watt light bulb? explanation .

(100 watts) x (1 horse / 746 watts) = (100/746) horse = 0.134 horse

This calculation assumes that a horse can produce power continuously at the rate of one horsepower.

But wait ! This MAY be a trick question.

100 watts is 0.134 of 1 horsepower. That much is true.

But the question asked "How many horses would it take ?". The answer to THAT question is "1.00 horse".

The reason is simple:

==> IF a horse always produces power at the rate of one horsepower (746 watts),

and

==> IF you want to hire only enough horses to produce 100 watts,

then

==> as a city boy, you might think that you need to slice off 0.134 of a horse. But horses don't work that way. They only work in multiples of a whole horse, and they have a very strong union. If you put 0.134 of a horse to work, the power output is zero !

To get any amount of power UP TO 746 watts, you need a whole horse.

as technology advances, new experiments often expose problems in accepted theories. c

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
