I was reading an article where a guy used water to cool the top of his house, it ran down the roof, then he had a pump recycle it and cool the house again with the same water. Occasionally he had to add more water but he said it worked fine. You think this would be an economical way to cool a concrete house with a concrete roof?

In a small rectangular, we're trying to find the height and width.
We only have the following data:

The diagonal is 7" (A=7)
And the Width is 0,6x the height (C=0.6xB)

What's the answer, and how do you get the answer?

Btw, this is no school task, this is just for me to calculate if the eeepc has a big enough screen for my liking.

when lightning strikes water it travels through the water right, branching out and effecting everything thats in the water sort of like when a radio slips into a bathtub. Then why is it that we have so much fish in our oceans, when there is so many lightning storms over the oceans at any given time? When a lightning strikes water does it kill every living thing in the water? Is it true that whenever a lightning strikes water all the fish die in the vicinity, how large is the radius of effect?

also electric eels, when they send of an electric charge don't they run the risk of killing themselves?

I was shopping at a fish market in Baja California and saw this really strange looking animal for sale on ice. I have never seen anything like it on sale for human consumption... so I was curious to know if anyone can explain what it it. They were small bunches of finger long tentacles that were sort of a maroon color. The skin of the tentacles looked scaley... they definitely looked like some sort of animal that anchors itself to something. The tentacle ended in white claw looking heads with white scales/plates. What could it possibly be?
