Can anyone outline, and this is a rather large request, the step by step integration by parts for <C>? This is not a homework question but more something i need to be able to do on tuesday for my final, and have been trying to do for two days.
Hey can someone tell me the value of the integral of X^2 exp (-aX^2) dx from zero to infinity. I have the general solution from a table of integrals but since the upper limit is infinity, I can't really plug these numbers in. Can't find it in a table of integrals anywhere? If anyone has the...
Further Questions Pressure, Temp Volume etc
Thanks for you quick response,
Ok so I looked back in my text and it specifically defines Dalton's Law as Ptotal=[ntotalRT/V] where ntotal is the total number of moles of gas present. the molar ratio is defined as Xk=nk/ntotal=Pk/Ptotal. I would...
Ok so I am doing this problem and it is making me insane. The problem states that you have a container, the container has a partition and in compartment A you have an ideal gas at 5 atm and 400K. In compartment B you have another ideal gas at 8 atm and 400K. The partition is removed and the...
Ok so I am trying to expand my understanding of these two concepts. Here is what I understand so far.
There are very few Schrodinger Equations that are exactly solvable
Both Theories are used to approximate a solution
Perturbation Theory utilizes a similar function with a known solution and...
The formula they gave us to find the normalization constant for a QM harmonic oscillator is Nv=((1/pi)^1/2(1/((2^v)v!)) where v is the wavenumber if that is any consolation. I am not interested in math thoroughly enough to lose any sleep over how you integrate exp(-ax^2) but i know some people...
Ok so I found a formula
Which gives you the normalization constant for the QM harmonic Oscillator. New question. How do you calculate the uncertainty in position for a QM harmonic oscillator?
Hey thanks for your quick response, I tried integration by parts, the only problem that i have with it is that whether i assign exp(-ax^2) to dv or u i end up having to do the integral of exp(-ax^2). Cause you take the derivative for du and you get (-4ax)exp(-2ax^2). use it as dv and you still...
Ok so i have been instructed to normalize N*x*exp(-ax^2), so i squared the function and trying to take the integral. I am a) assuming that the integration should run from the negative value of the amplitude or -A to the positive value of the Amplitude of A, i have a formula for A. My assumption...
Ok so my homework question says find the de broglie wavelength of a 100 gram ball traveling at 100 miles per hour. So do a little dimensional analysis and 100 mph is 44.704 m/s and since the de broglie wavelength is found with lamda=h/p and p=mv then I am good to go, I get 1.48 x 10^(-24)...
I see what you are saying, they way our book presents it is that C is equal to 1 over the equation. So we got the entire C=1/[P(Xi)] thing. Here is the exact question as it is worded in my book: "...we shall find that the probability of a system occupying an energy state with energy E is...
