comment Symmetry Breaking And Phase transition
This doesn't appear to actually answer the questions asked, though it is tangentially related.

comment What physical properties of silver would contribute to the sound of a musical instrument?
Do you think you can be a bit more specific about what you mean by "sound"? As in what aspects of the sound are of interest here. Reading the linked question, I guess something like "purity of tone" (which is something we could discuss with physics) might be of interest. Or maybe how long a ring lasts once bell is struck (something about damping of oscillations in the instrument). What aspects of the sound are you interested in having explained by a "good" answer to this question?

comment Why the center of our galaxy doesn't absorb us?
Not sure if this is meant to be commentary on one of the other answers, or an actual answer to the question. Either way, it's pretty vague and I'm pretty sure parts of it are just wrong. Would you consider making an edit to clarify: what your first sentence is responding to (this seems a bit confrontational as well), and what mechanism you're suggesting is causing the decay of the solar orbit? Also, the Earth doesn't collide with the Sun because it is orbiting it, which has at bet very little to do with our orbit around the galactic centre.

comment Is the universe flat?
Diagram describing various properties and behaviour of universes with matter & cosmological constant (i.e. radiation energy density negligible). "Flat" is any universe on the line between open and closed (notice that this is NOT the same as will/will not recollapse!!!). Negative cosmological constants are allowed in this diagram, and behave as a constant attractive term instead of a constant repulsive one. astro.uni-wuppertal.de/~kampert/Kosmologie-Bilder/…

comment Electric field intensity of spherical shell (with cut out cap)
Well, first, what do you think? We typically don't solve textbook style problems from scratch here. If you have an attempted solution we're happy to comment on why we think it's correct or incorrect. Please read the homework policy physics.stackexchange.com/tags/homework/info (which applies to homework-like questions as well as actual homework).

Can you explain how equilibrium allows this, or otherwise elaborate a bit more?
