Also an electron is made up of a quark and anti-quark: a Down quark and an Anti Up quark. The Down quark has a charge of -1/3 (e), where e is the charge of an electron (in absolute value) and the Anti Up quark has a charge of -2/3 (e), giving you -1 (e). And P = E/c and E = hc/lambda, where lambda is the wavelength of the photon of light, so plug in the values and you will get the answer. Also, F = (k * Q*Q')/r^2 r and the electric field is F = Q E, so Q' does not mean its an electron or whatever, its the value of charge of the particle you are talking about. This is usually also for point like charges. So for the case of an electron it has a certain charge (e) you plug that in for the value of Q' and Q is the "test charge" at which you are looking at the electric field.

I see. The initial state is not known until time has elapsed, of course a very small time. So I believe the second input you are talking about that the NAND Gates are receiving at t = 0 is just a logic 0 or 0 volts, until time has elapsed and it is receiving the desired input/output combination. And even though this seems like a non-casual system (a system that does depend on an input at t greater than your current t), it does not change once the inputs are set. You are really only getting a delay, which you will learn more about in labs hopefully, though an easy idea to consider due to physical restrictions.

So are you talking about a SR Latch without out a control value and if so can you can explain a little better, what you are unclear about? Because I am not sure what you are referring to when you talk about Null? Do you mean when S = 1 and R = 1? Which is when it is undefined...

Probably through electrolysis : http://en.wikipedia.org/wiki/Electrolysis_of_water , but why?

Pretty much as he stated. 1 cubic centimeter is equal to 1 milliliter Think of it this way: if you were to imagine a cube in which each side was a 1cm by 1cm square, so the volume of that square is (height X width X depth) = (1cm X 1cm X 1cm), which is the same as 1cm^3 or 1 cubic centimeter. Now that you have this cube that has a volume of 1 cubic centimeter. Imagine filling this cube with water. How much water that is in this cube is 1 mL; therefore 1 cm^3 = 1 mL

timo, not really sure what you are trying to say there. my point seemed pretty clear, except for one correction that gamma (γ) is 1/(1-(v^2/c^2))^1/2 And Klaynos, the poster's example was specifically about moving objects, where E=mc^2 does not give accurate results, only E=γmc^2 and p would not equal 0. Edit: nvm, was wondering where the poster got 2 for gamma, but he states it wrong, he should have 86.6% not .866%

Why is it that no one understands it's E=γmc^2 where γ= (1 - (v^2/c^2))^1/2. Therefore at rest v = 0 and γ = 1 and you get your famous E=mc^2

To add: the current magnetic shocks they use, I believe have some type of chemical/liquid that can be charged to generate repulsion/attraction when needed.

I concur with ajb. Everything can be quantized, including waves, down to packets of waves (photons). It's essentially what Quantum Mechanics is based off of. Everything has a definite, finite amount.

In my opinion, if you know calculus, multi-variable calculus is not a big deal. Now differential equations are another story. I'm not sure what your modern physics class is like there, but if its just a GEC (General Education Course), it shouldn't be that bad mathematically. My Modern Physics class we are actually solving Schrodinger's Equations and learning Quantum Mechanics, but that's just the way it is set up. But I would say if you have room to take the next math up, do it. It is always worth knowing more math, especially for physics and sciences.
