I'm trying to show that the amplitude (A) of the wavefunction for a particle in a box is:
A = sqrt(2/L) : L is the length of the box.
I'm using \psi(x) = Asin ((n*pi*x) / L) as the wave equation.
To do this I'm trying to integrate the probabilty density function from 0 through to L...
So we (the universe) observe no charged particles enter a black hole. All the "information of charge" or photons (the gauge boson of the electromagnetic force?) are trapped on the event horizon.
So is the definition of the net charge of a black hole
The net charge of mass trapped just...
So black holes, nothing can escape.. not even light.
Now let us imagine a black hole of arbritary size, and we throw a heape of charged particles (electrons say) into the black hole (negative net charge). Laws of physics state that charge cannot be created nor destroyed. So when this...
Mmm energy conservation i get, I am just trying to figure out the work done?
I've the force at the most compressed point, but it changes over the 0.2m it acts upon?
- what am i missing?

I mananged to find the acceleration up the slope but cannot get any further than this?
- can someone please give me hint; push in the right direction
Thanks :D

A monatomic gas has V1 P1 and T1 (volume pressure and temp) at state 1
The gas then goes through the following process
adiabatic expansion to stage 2 (exapands to twice its volume)
isovolumetric heating so it gets back to T1; stage 3
isothermal compression back to...
1/0 is undefined, anything divided by zero is undefined.
But, as AUK 1138 mentioned it is better said that as r tends towards a very small number ( i.e. gets closer and closer to zero ) the fraction will tend towarda bigger and bigger number ( i.e. tend towards infinity ). But at r = 0 the...
