comment Capacitors in series?
I guess your question has less to do with capacitors per se and more with induction and the field of conducting plates. I have edited my answer.

comment Capacitors in series?
Because the charges on one plate of a capacitor will electrically attract opposite charges on the other plate of the capacitor.

comment Phonon mode in canonical and grand canonical ensemble
Yes, but in the grand canonical picture, you look at these equidistant energy levels and interpret them as individual particles, the phonons. Instead of saying "The oscillator is in the $n$-th excited state and thus has energy $\hbar \omega n$, you say "There are $n$ phonons in the system, each with energy $\hbar \omega$. What you're doing wrong in the grand canonical treatment is double-counting the energy levels: You're assuming that each energy level of the oscillator can be multiply occupied.

comment Tensor of inertia
Yes. You'd expect the tensor of inertia of that hemisphere about that axis be exactly half of the tensor of inertia of the full sphere, and then it's just a matter of substituting m for $M/2$.

comment How to calculate the van der Waals force from the van der Walls equation?
There's a nice statistical-mechanics derivation on the English Wikipedia entry for the Van-der-Waals equation.

In that case, use conservation of angular momentum as in the other answer :)

comment How can I explain this fallacy of conveying information faster than Light?
Also, the movement of the spot itself is delayed from the movement of the actuator by precisely the time it takes light to travel that way.

comment How do I measure the spin along an arbitrary direction?
Okay. I'd still keep the homework tag because it's a somewhat basic / instructional question. Now just look at vnb's answer and use his hint :)
