I have read dozens of times that if the polar caps melt, it will raise sea levels by 10-50 feet.

Since 90% of the polar caps and iceburgs are underwater, and since ice takes up more space than water, wouldn't sea levels actually drop - or at least stay the same - if the polar regions melted?

I was looking at satellite images of the moon on the Clementine Lunar Image Browser http://www.cmf.nrl.navy.mil/clementine/clib/
I found it weird that several area on the far side of the moon looked rather blurry, (like they where erased or air brushed). When I clicked on to some particularly obvious smudged out areas, to enhance I got a message that particular spot of the moon was unavalible to view close up. There where a few spots on the front side as well. Something weird seems to be going on so I checked out other sights, and the same thing happened. You can see every square inch of earth through the terra server, (except military bases) With the moon being so much smaller we should have perfect images. Anyone know of a good lunar sight that doesn't have restrictions?

All the maths questions have triggered something in my memory.

I'm sure there is a numerical means of working out a square root - but I can't remember it. Can anyone help?

Hi
I am doing a project and need to know some items which contain salts.
E.g - Toothpaste contains sodium fluoride, Fertiliser contains Magnesium Sulphate. Things like that please. Preferably things that you can find around the home but anything will do.
Thanks x

Also, if you know the acid which the salt is made from that would be extremely helpful. Eg Sodium Chlorise is from hydrochloric acid. Thanks again !

I made a permanent magnet motor, that turns fast enough to maybe create charge. I need to know what sorts of electrical motors will make a dc current. Can I use any battery operated motor, like out of a handheld fan or a remote control car?
Is there a "best" way to make electricity with a rotating shaft?

Imagine a straight line going from the Little Dipper
to the Big Dipper. Following this straight line past
the Big Dipper you meet a very bright star. This star
is halfway closer to the Big Dipper than the Little
Dipper is, and is the very first bright star you meet
following this straight line after the Big Dipper.
Can you tell me what the name of this star (or planet) is?
