ya he's not really a great guy... i don't even know if that was the exact answer he was looking for, but it was right since he was so vague and oh yeah...kinetic watches? that's also like free electricity and is sort of like the same concept as the nanotechnology stuff

there's no problem berkeman. I found the answer! Here is the story: I got the class together before it started on Thursday to propose my answer and showed them http://www.technologyreview.com/Nanotech/16746/" and they although hesitant, gave the ok. They said I should give the professor the...

i laughed unbelievably a lot with berkeman's post in https://www.physicsforums.com/showthread.php?t=177467". lol... i specifically said not by stealing. i said in that thread that it was A) for class and B)anything that's not illegal although i wouldn't mind him being "reprimanded" since i...

sorry, i forgot to include that. he's not saying free in terms of free energy like in gibbs free energy from chemistry or anything. he's using free in terms of money. free meaning you don't have to pay for it. and not by any illegal means like stealing, lol. So think of it like this...

Hey everyone. I'm taking physics 2 right now in the summer and my professor keeps saying you can get free electricity, but doesn't tell us how. He's pretty stuck up and has been saying this since class started 3 weeks ago. It's really annoying and as a class we want him to shut up. Well, that's...

i wish i liked studying... man ur lucky

Can some body please help me on my homework. The problem is in the link image below (click to go to it) http://img501.imageshack.us/img501/1126/helplr7.jpg" I'd know how to do that problem if it said "initial rate (M/s)" in the last column, but it says "Reaction time (seconds)" and I...

This question is about plasma membranes. The molecule that acts as a temperature buffer in animal plasma membranes is: A) Collagen B) Phospholipid C) Cholesterol D) Proteins Help is appreciated! :!)

the new IE looks nice. looks like they are finally doing tabbed browsing as well... but firefox rules... and i will never switch back 2 IE as long as the Fox is around!

:cry: i just don't understand. there's like a physics block in my mind. can somebody please solve for me.

is the kinetic energy of the cylinder .5mv^2 = .5MR^2

KE=.5mv2 and PE=mgh point 1 = PE point 2 = KE + PE so it would be mgh = .5mv2 + mgh

i don't know how to do that :cry: please walk me through

they possesses Kinetic Energy if they are in motion.

Homework Statement http://img172.imageshack.us/img172/5227/4rj8.jpg Homework Equations Not sure, but I think KE=.5mv[SIZE="3"]2 and PE=mgh are two possibly useful equations for this problem. The Attempt at a Solution I have no idea how to even start this problem. I've been...
