ok ok I know about power stations and transformers, but how when i plug something in is electricity waiting. Is it like water drawing on a big pool of electricity or is electricity so fast that you put a turbine on and immediately I have power! what happens when not enough is used, does it just sit there waiting to be used?

When we place objects of different temperatures in a room, they usually come to the same temperature. But a damp object, even if it starts at room temperature, becomes cooler than the room. How does this play into the second law of thermodynamics?

Fish are attracted to the warm water released by nuclear powerplants. This means an abundance of fish. I am wondering if it is safe to catch fish in warm water released by nuclear powerplants and then eat them.

Experts have only been able to conjecture how the Egyptian's were able to build the pyramids. Has anyone asked this question. Are we sure the Egyptian's built them? Could it have been an advanced intelligence from another world that built them as markers so if a space traveler saw them from space they would know they were here?
The pyramids are one of the few m anmade things that can be seen from space.

I was trying to purchase or find free software that allows you to practice solving reaction problems or also allows you to review and practice important organic chemistry concepts. Software similar I guess you would say to the Jump Start they have available for younger children.

I'm Designing a peice of furniture and have reached a problem with its structure. I need some advice by some one with knowledge of matterial strengths to advise me on joining two sheets of material. Can any one help?

I will be more specific then. I'm trying to join two sheets of 18mm thick poplar plywood board together at 90 degrees. it needs to be mega strong but not be any thicker than the 18mm. I thought of dovetail joints but i can add components to make it stronger. additional components could be used.

Momentum is inertia in motion, and is equal to the product of a body's mass and its velocity. For example, if the speed of a projected canonball is doubled, then the momentum is doubled. Or if instead the cannonball's mass is doubled, then the momentum is likewise doubled. Suppose however, that a cannonball's mass is somehow doubled and its velocity is also doubled. The its momentum is:

a) the same
b) doubled
c) quadrupled
d) none of these

Choose only one final answer (please!). A correct answer accompanied by a correct response trumps only a correct answer (or guess) alone. Good luck!
