Wouldn't pressure (pressure= Force / area) have something to do w/ why a sledge hammer (force spread over a small surface area) would inflict more damage than a roll over ( force spread over a large surface area)?

10 ft of water is 10 ft of water in this case, neglecting the percentage of salts and other things that vary chemically w/n the two bodies of water they should freeze at the same time. They both will form a sheet of ice on the top 1st. This has absolutely nothing to do w/ where the water is...

Here's the link to that thread: https://www.physicsforums.com/showthread.php?s=&threadid=500 your welcome .

There's a thread just like this somewhere. If you take the time to look you'll be rewarded w/ plenty of good suggestions. I remember one poster came up w/ a free online textbook you can just download and print. I always recommend Paul G. Hewitt's Conceptual Physics, it comes in both high...

A lot of people like 'The Elegant Universe' by Brian Greene. When you talk about i-electrons and d-electrons I'm wondering if your talking about the difference between valence electrons and inner-shell electrons or maybe should be focused on that more. I just don't get your interest in the...

Thanks Andy, anybody else give it a try?

Gas station exploding? I know this is a crazy to ask right now but me and my roomate just came out of a gas station and an early model BMW pulls in front of us and was dripping flames under the hood right by the pumps. We told the guy to get it away from the pumps so he manages pushes just...

I definitely concur. I have no idea what you're trying to ask. You sound like you know the concepts behind the Heisenberg uncertainty principle...possibly wave-particle duality, but I'm not too sure if you comprehend the relation between the electron and EM waves. Like Andy said if you keep...

I should quickly mention that the scale model is false in the sense that it would imply that space and time are equally proportional to one another and they're not. Simply put going half the speed of light does not mean you reduce time by a half. You have to travel pretty close to the speed of...

Your always traveling at the speed of light. The thing is you travel at the speed of light through both space and time. Think of space and time as the two trays on a balancing scale, w/ one one tray representing space and the other tray representing time. When you are standing completely...

Tail, you (the person/twin on the space craft) will not feel time slowing down at all it will feel no different than time feels to you now. It is the twin on Earth that 'percieves' your time slowing in that he would have aged significantly more than you and the wrinkles on his face and the lack...

Thanks for clearing that up Lurch:wink:. I have another question though that I can't figure out, why does the flame go out when you blow hard on it? My guess is it's b/c your blowing CO2 and not molecular oxygen, is that correct?

Do you mean color or colour? If you mean color then the same answer applies as before only the difference is how the electron relates to the EM wave. The electronic vibration or excitation/relaxation is what sends out an EM wave(*kind of the same thing as vibration but more energetic, to the...

Yes and no I guess (in a loose philosophical sense since we can argue all day about what is 'real'). What we, as humans, see of an atom or collection of atoms is a very narrow range of the spectrum and the sensors in your eyes assign a particular color to a particular wavelength. What we as...

Just to add to what everybody else has said and to make sure I have the concepts right myself (and please correct me if I'm wrong). Like HOI already stated molecular oxygen(g) meets w/ carbon, oxidation occurs, and yields carbon monoxide, carbon dioxide, etc,. These are the molecules that are...
