Nuclear fusion is when the nuclei of two atoms fuse together, forming a larger atom, which releases energy.
Ice can be colder than zero degrees centigrade; there is no law that keeps ice at zero degrees. If there were such a law, then ice would be a perfectly clean, infinite source of energy. We could simply pump heat out of ice, and the heat would never diminish. But this is not the case. So it is possible to add water ices of different temperatures and in the long run the temperatures would balance out.
it have many ways to work
no;1 it can be work with the help of a marble
no;2 it can be work with a pencil
no;3 it can also work with a good minimoter
this what i know if some one want know more about it you can go in google and type this newtons disc
A dam works by the movemoent of water when the water is full the dam will the let all of the water out and it repeats over and over again
A dam works by blocking the flow of the river by storing water, which forms a resorvior up stream from the dam. as water continues to flow from the river up stream from the dam.

Waves are of three types (on the basis of their crashing on the shore):
Spilling Breakers In a Spilling Breaker, the energy which the wave has transported over many miles of sea is released gradually over a considerable distance. The wave peaks up until it is very steep but not vertical. Only the topmost portion of the wave curls over and descends on the forward slope of the wave, where it then slides down into the trough . This process is why these waves may look like an advancing line of foam.
Plunging Breakers In a Plunging Breaker, the energy is released suddenly into a downwardly directed mass of water. A considerable amount of air is trapped when this happens and this air escapes explosively behind the wave, throwing water high above the surface. The plunging breaker is characterized by a loud explosive sound and are more commonly found on the west coast of North America and the Pacific Ocean.
In surging waves, the wave crest tends to advance faster than the base of the wave, which would suggest the formation of a plunging wave. However, the wave then advances faster than the crest, the plunging is arrested, and the breaker surges up the beach face as a wall of water which may or may not be white water. These waves are usually found on beaches with a very steep slope.
