Thank you for your help. Let me make it clear, the occupancy of any energy level is decided by the total energy of the system, so my question cannot be answered only if we add an additional energy parameter, right?

Hi, can anybody help me with this problem? I am currently study quantum mechanics and am confused with the BE staticstics. OK, say there are N Bosons in a system with two energy levels. The lower energy level is 0 and the upper level is E. The question is what is the average occupancy of the...

For the second part, z>>R E=\frac{\sigma}{2\epsilon_{0}}[(1-\frac{z}{\sqrt{z^2}}] Wouldn't this mean E=0? You missed a second-order term here! :smile:

That is not true. The ratio tends to be infinite (it is compatitable with n).

I had to look up some power consumption data. If a human runs at 24 km/h, the power consumption is about 1.7 kW. So it's not a feasible construction (not for me at least). Maybe I am out of the thread. But I wonder how 1.7 kw was reasoned out. If we consider a pure mechanical way( the...
