its true form with its active volcanoes? And don't you think with the earth fragile structures that we should be starting to think about the result of the green house effect in the near future?.

I heard that with in the next 10 years the Earth will reverse the way it turns on its axis and this will result in the end of all electronics as we know it ( no internet, tv radio etc.). We will have to start all over again. Have you heard of this and where can I find more info on it?.

I had a 9V battery hooked up to a tiny yellow LED light and it went dead after two days of being on. There was a 250Ohm resister hooked up after the negative end of the battery (as per the instructions of the guy at Radio Shack.)

I really thought that setup would remain on for months on end with no problem. I thought a LED light takes up barely any electricity.

How do you solve B=3/4(A-10), for A?
Thanks.
Also, by the way, don't just give me the answer. Can you tell me how to work it out?

A farmer owned two pieces of land. the first was eight times larger in area then the other, and the two were separated by an access road. When the farmer measured the perimeters of both sections of land, she was surprised to find that it was going to take twice as much fencing to surround the smaller area than it was to surround the larger! Both sections of land were rectangular in shape and the fences were continuous. (the gates should be counted as part of the fence). How much fencing did she need to buy?

If hydropower is the clean energy source that it has always been, why not find new ways to use it in places where it wouldn't displace anyone like in secluded rural areas? They would make excellent tourist attractions for fishing and scenery. Another thing I ran across is that all too often the water that could be used to generate power just goes over the top of the dam instead of running it through the generators. I want to hear the common person’s opinion on why or why not to use these almost free energy sources.

You know, as Einstein said, all energy has an equivalent mass - E equals em cee squared and all that. So each object should carry, besides its own mass, the little bundle of mass equivalent to its gravitational energy.
