Homework Statement
[PLAIN]http://img708.imageshack.us/img708/8725/mathhelp.gif
I can kinda see that p(x) will be smaller than L1 and larger than Ln, but I have no idea of how to prove it. As a side note; p(x) is really the rayleigh quotient.
Please help, I sat up till very late last...
Ive got the equation: sin(x) = ln(y) + (y^2)/2 + k
The k is a constant from an earlier integration. How do I isolate y? What makes it hard for me is that if i want to get rid of ln() i need to use exp() but then the other y is in exp() and if i want to get rid of that, the first y is in ln()...
Thanks for the reply :)
hmm, sorry if I misunderstand, but isn't the spin in electrons different from what we know as rotation. I mean the electrons have up and down spin although planets and alike is spinning around and axis that can point in any direction.
Im not really into field-theory...
The wikipedia page on black-holes (http://en.wikipedia.org/wiki/Black_hole#Properties_and_features) tells us that the effects of charge and rotation of black-holes have both been observed. Guass's law tells us that "the total electric flux going out of a big sphere always stays the same, and...
I'm sorry if this is not the right place to ask such question and sorry for misspelling, but here goes
I wonder how Black-Holes can rotate and be charged..
As far as I know a black-hole consists of a singularity which is a point with unlimited density and the event horizon. The singurality is...
Imagine you were safely enchambered right at the center of the earth. Here you would "experience" strong gravitational "forces" but since they all point in opposite directions you would float around as if you were in zero-gravity.
My question is, whether you would experience time dilation or...
My question is quite simple
Imagine a massive object speed by you. We know that everything including gravity abides the law that nothing can travel faster than light. Therefore it will take a little bit of time for the objects gravity to reach you, but in the time spent for the gravity to...
"Behavior of light accelerating"
Imagine a spaceship which has got a small lightbulb standing on the floor. You turn on the lightbulb and the light shoots towards the ceiling, but before the light reaches the ceiling the spaceship accelerates a bit and stay at some velocity.
My question is...
Ah,,, I forgot to take into account that when the spaceship accelerated from 0 to 0,5c the clocks got out of synch..
Well, many thanks JesseM for the quick yet very detailed answer ^^ you too Janus!
I was thinking of this thought experiment the other day and it didnt quite seem to make sense to me. I hope some of you can explain it. I have drawn a quick example of the setup:
and sorry for my english
(c = 1 m/s)
Imagine a 1 meter long spaceship with a velocity of 0,5 m/s (c/2). The...
