What about the etched one which leaves a dense oxide layer as mentioned in one of the above posts?

Why can the gaskets be made out of Aluminum instead of copper? The stainless steel of the flange can easily bite into the Aluminum creating a good seal. Also Anodized Aluminum is bsetter than copper since copper oxidizes very readily when left outside. And I always have a problem with brand new...

Aahh, thank you Borek. The limitations of classical physics I suppose. :)

So suppose I encounter a material that is a classical solid, would it be safe to substitute 3R for its specific heat when I am calculating its Q per mole?

Hi there, I have a quick question. According to duLong and petit's law, the heat capacity at constant volume for most solids at high temperatures is 3R. (I.e) Cv=3R. Where R is the gas constant. Does this mean that the heat capacity is the same for all materials? I thought each material at a...

I know I am asking a really dumb question. But can you please explain how electrons move in an Alternating Current through a circuit?

Then how is the circuit completed? Cos the circuit is grounded. And I am pretty much sure there is no depletion of electrons. the electrons can't be replenished from the air, cos antenna works in space also!

Thanks for the replies guys. @ Clem, How is the AC EMF fed to the circuitry of the reciever once it passes thru the antenna stage? Is there a terminal EMF or something which is created at the feedline of the antenna? After that how does it get into the circuit? I know very well that the...

Hey there everybody. I have a question which till date no professor has been able to answer. At least as far as I know. Its a basic antenna question. We all know that any moving charged particle generates EM waves. That is how an antenna works, when the electrons on the antenna are...
