- Firstly, sorry it took me so long to reply. I have to say I was stumped by your question and was looking for my notes when I learned about the equation, but unfortunately I couldn't find them.
- I'm just going to tell you what I know. When I learned it, my professor wrote the equation...
- Unlike the next two questions, this one is actually more difficult for me to answer because although the very fact itself is obvious, I can think of several explanations, but none of them seem to really explain it as well as I would like. So I'll leave this question for someone else or maybe...
I'm not sure if this is the right place to post this topic, but I need some opinions.
I would really love to learn General Relativity. I possesses a working knowledge of tensors (namely tensor calculus and analysis).
Upon doing some research I was told Gravitation by Misner, Thorne, and...
It was just shorter to say I have straight A+'s and mention I have 2 A's later on. I have straight A+'s and 3 A's now. But as I said, my grades are immaterial, it's what I know that characterizes me, not what's on paper.
I want to thank you all for the advice. I've also been speaking with his...
Hi all,
I need some opinions on my situation:
- In my school, in general, 90% and above is considered an A+ and gets you a 4.3 GPA (highest) for that course. Professors have the right to alter the grading scheme. I currently obtained an A for a course which I suspected I would get an A+...
Not that it matters anymore, but the solution requires knowledge in exponential integrals. It does not have an absolute antiderivative. The antiderivative itself must be expressed in terms of exponential integrals. For the user that used Wolfram, the Ei stands for exponential integral.
If we would build a copper ring that would orbit around the Earth (like a big belt), could we generate electricity from it (because of the Earth's magnetic field). I know it's impractical, but I'm curious as to how much electricity we could get.
There is a lot that could happen if the moon was heavier:
- The best way to approach this problem is to consider an extreme scenario like Europa (a satellite of Jupiter's). Jupiter is really big compared to Europa. The eccentricity of its orbit causes Jupiter to distort Europa (by stretching...
You should check out the Saha Ionization Equation(s) (or Saha-Langmuir Equation). I must say, wikipedia actually has a good page on the equation(s) and its use.
Exactly azizlwl.
The main problem in math proofs is that you sort of have to trick the solution into appearing (which is usually not obvious). But maybe for future reference, if you ever encounter such problems again, the way I start is by coming up with ways of getting what I want (necessary...
It is correct.
- The main cause of ionization is the first force:
The oxygen atom within the water molecule is more negatively charged than the rest of the molecule (there is a permanent dipole in the molecule). This causes the molecule to attract positively charged ions on the oxygen part...
- The equation seems right, but then again why wouldn't the material derivative of acceleration apply (as in fluid mechanics). Is there an assumption I am missing that doesn't apply to ordinary particles? The equation is:
\vec{a} = \frac{D\vec{v}}{Dt} = \vec{v}\cdot(\vec{\nabla}\vec{v}) +...
- I can't say whether your question is entirely valid or not because the truth is I don't precisely know the answer to your question.
- What I do know however, is that in modelling physical systems, we call the s-domain the "frequency domain" whereas the t-domain would be called the...
Oh, I'm so sorry, I am new to the forum and have only skimmed over the rules. Thank you for notifying me, I will read the entire forum rules so I don't make such mistakes again.
