Thanks for your help, George and nrqed. I also took the assumption that the particles cannot interact and so the third particle only has energy zero, leading to only three states. I admit the question is definitely ambiguous, but that seems to be one of the those things which seem to occur...

[SOLVED] Basic Statistical Thermodynamics Homework Statement Two distinguishable particles are to be distributed among nondegenerate energy levels 0,e,2e,3e... such that the total energy is U = 2e If a distinguishable particle with zero energy is added to the system show that the entropy...

cesiumfrog, Sorry if I sounded like a computer, just churning numbers without thinking. The reason was because me and my friends had already discussed (Or at least try to understand) the physical aspects of the question. What I believe is happening is that when the memory is erased, you...

So essentially what you are saying is that jlmac2001's questions A & B can not be calculated using the formula I stated in my previous post [S = k*ln(W)], but will have to involve other more complicated ones? If that is so, it seems to me that we are reading too deeply into the question. I...

Hmm...this indeed appears to be quite an interesting question. (I am currently studying Thermal Physics!) I think here we are meant to take the thermodynamic definition of entropy. More specifically, I think we are dealing with the equation S = k*ln(W), where S is entropy, W is multiplicity...

As a helium balloon increases in altitude, the density of the air inside decreases. However, the density of the air surrounding it (The atmosphere) also decreases with altitude p=p0*exp(-z/z0), where z0 is the scale height of the atmosphere. So does this mean the lift force acting on the...

Okay...I checked up on my lecturer who wrote this question, and he said that he had forgotten to put in an initial velocity v(i). But I'm still not sure on what you are doing with the angular velocity. Are you saying that the angular momentum is mv(i) x (a/2j + c/2k)? Regards, The Keck

Thanks, I understand what you mean now, it's just I didn't really think about it using that reasoning Regards, The Keck

So that would mean you actually need the initial velocity of the particle m, cause the question seems to indicate you don't need it. (I a bit confused about what you are doing...are you finding w and v independently and then use the fact that v=a*w or something?) I'll check up on that the...

No, I'm pretty sure I didn't make a mistake. dV/dx= (-4 x -A)/r^5 = (4xA)/(r^5) -dV/dx = F(x) = -4A/(r^5) Regards, The Keck

Homework Statement A charged particle of mass m moves non-relativistically around a circular orbit. The potential energy is U(r)= -A/r^4. What is the sign of A and why? Using Bohr's quantization for angular momentum to calculate the allowed values of the radius. Homework Equations...

Homework Statement A uniform symmetric ellipsoid (Mass M) has a large semi axis c and small semi axis a. A particle of mass m<<M is moving along a straight line parallel to the x-axis. Its y-coordinate is a/2 and its z-coordinate it c/2. After an inelastic collision, it sticks to the ellipsoid...

I was looking at your solution and a problem came into my head which relates to the ground state wave function. I noticed that the function is actually independent of theta and phi (Spherical coordinates). But what does that actually imply in terms of where the electrons are distributed in the...

Thanks a lot, mate! I used a different reference system, which sort of stuffed me upRegards, The Keck
