This image (see link below) shoes a Cavendish appartus like the one used to find G. It has a large lead...?

You could just use the old force = (G*M*m)/r^2\nWhat is missing from the diagram is that the small weights were held by a long thin wire.  The wire formed a weak torsional spring.  If there were some gravitational force, it would cause the weights to twist the wire until the torque of the twisted wire matched the force of gravitation (times the radius).  He could measure the amount of twist by shining a light at a mirror attached to the weights and seeing how far the reflection moved.

What you describe looks as if it is a gum from the tree(usually)which has settled on the rock and has the natural salts of the rock diffused into it . If you are still in trouble then go to the nearest research Lab to get the exact details of the elements present in this specimen.

Had a hard time myself searching for it \n\nThis was the best I could come up with\n\nhttp://www.britishlegion.org.uk/index.cfm?asset_id=513181

Look for any of these marks:\n\nSilver- Ster, Sterling, 800, 900, 925\n\nGold- 585, 9K, 10K, 12K, 14K, ect.\n\nIf they are unmarked:\n\nDo not acid test, especially silver! Take them to a Jeweler. Most of the time, they will tell you for free.

Does it have Lincoln on it?  Then it's not real.\n\nHowever, if it is real (look at it here: http://www.bcpl.net/~etowner/coin794o.jpg), it's worth a pretty penny.  (heh)  Not as much as if it hadn't been cleaned, however.\n\nHere's one on eBay\nhttp://images.google.com/imgres?imgurl=http://i14.ebayimg.com/04/i/07/fe/e1/12_1_b.JPG&imgrefurl=http://cgi.ebay.com/1793-United-States-Large-Cent-Penny-KEY-GUARANTEED_W0QQitemZ220016802295QQihZ012QQcategoryZ11946QQcmdZViewItem&h=300&w=400&sz=33&hl=en&start=2&tbnid=YWRagJ3oGyG-LM:&tbnh=93&tbnw=124&prev=/images%3Fq%3Dpenny%2B1793%2Bunited%2Bstates%26svnum%3D10%26hl%3Den%26lr%3D%26sa%3DG

Yellow Ledbetter maybe?

a belt is driven across a surface rubbing the two together to make 'static', which is basically just free electrons. they collect in the big metallic ball, and when the potential is high enough between the ball and another conductor (or a conductor is brough close enough), the electrons 'jump the gap' to get to ground, and you see the big spark!\n\nWant to build one? Here's how:

I don't have an answer for you except that it has something to do with the softness of the lead, I think.  But that made me laugh, so thanks for that, and thanks for the 2  :-)

You said a hidden tresure, if it hidden what make you think you will be able to find it?\n\nYou could check the website below, or look in a Treasury

GEORGE DE MESTREL, and William otis both invented two important things which people are not aware of.  If you recive this it is your task to find out.  i give you a clue for one look at the end of your shoe lace.

Okay, it's been a looooooong time since I had to use my chemistry skills, so lets see what I have:\n\nCopper is more magnetic with electrons than silver is because it's electrons (with fewer of them) are close to the nucleus (or whatever you call it) of the element.  Silver is more apt to lose its electrons with them being so far away.  \n\nCopper is more often found in a +2 state.  So I'd say that's a safe bet to go with.  I'd only assume a +1 state if your teacher said so.\n\nSo therefore:  2AgNO3 + Cu -> Cu(NO3)2 + 2 Ag would probably be your best bet.\n\nBut once again, it's been a long time since I used this so I don't know how right I might be.

Please provide a link or something. You don't sound like you're kidding, do you? This is a very serious matter, the find of the year, I would call it.

Yeah, it shows.  At it is spelled neUrotic.\n\nAs long as you don't poke you eye out with it, it may at least make your tracing more even as the lead does not widen as it gets used.

I believe you would get £10-worth of silver, but only if you took it to the Band of England in Threadneedle st, London, in person. (If everyone did this there'd be a crisis because there wouldn't be enough silver to go round!)
