While solving questions on calorimetry particularly on state conversion and temperature of equilibrium
On questions on temperature of equilibrium equilibrium for example ice at -20 degrees celsius and of particular weight is kept with water of particular temperature in particular weight and both are isolated
What my teacher does is to bring them both to common state such as water or ice
If there is excess of heat loss or heat in then she uses it to raise the temperature of the state
I am not sure how this can be possible
Is it due to the fact that the state and temperature changes are reversible
example question is 10 gram ice at -10 degree Celsius and 50 gram water at 40 degree Celsius are kept together find the temperature of equilibrium
There was some recent media reporting about a purported Google breakthrough on applying machine learning techniques to tackle the protein folding problem, as told for example in this news article, DeepMind AI handles protein folding, which humbled previous software.
Unfortunately there is not muc...
If you take the point P that is a distance y away from the middle charge then the potential due to the middle charge is +kq/r, and the potentials due to the other two charges are -kq/r.
Where r² = d² + y²
You just add up the three potentials so the total potential is:
I'm already spending my willpower on not buying several early access titles, I have no willpower left to resist buying this one the moment it comes out
I was going to get it for PC, but I'm going to wait a bit and get a PS5 now I think. I decided to sell my Switch and games last week and got $600 store credit at a local place, so I said screw it and went on the list for a PS5, so I'll probably be playing that in like a year.
I only have a 1060 and a i5 6500 too, so a modern game like that would run real bad on my PC probably, whereas presumably they will at least have good console ports.
The nice thing is big cases still have mountings for the small factor motherboards too, so at least it would be basically as straightforward as buying a case and the GPU and moving everything over, instead of having to like mess with a heatsink and everything.
My case has glass panels in front of all the fans, and just strips on the side let air through. I thought it was going to make my CPU a lot warmer than my old case, but it didn't make a difference. It might just be because there's a ton of fans to force airflow anyways.
@geocalc33 because if you look at the question I linked, it has no answer, and in the linked question there's a characterization in terms of sheaves of vector spaces, not rings
I actually have a related follow-up question, why do we even close the contours in the first place when evaluating the $p^0$ integral?
Is it because when we take the radius of the "closing loop" to $R\rightarrow \infty$ it's contribution vanishes and we're just left with the integral along $\Bbb R$?
or rather, the integral along $\Bbb R$ that avoids the poles
Does anyone know an example of a reference frame for the complex momenta of two identical massive (on-shell) particles and one massless particle? Taking momentum conservation into account
it seems an easy question, but I am able to find a solution
I know an electron can have two spin states, "spin up" and "spin down", but recently I was asked how many spin states do $\ce{Cu^+}$ and $\ce{Cu^{2+}}$ have, and why? Does anyone know the answer? Thanks.
Unfortunately for me, I don't know any undergrad-level science. The only science I know is at the research level, and the NIST database shows hundreds of experimentally observed states. If one of you know what the undergrad textbooks say about what spin states are allowed, please add the answer for this poor soul who thought they would just get an answer to their homework question.
There's a proposal at the moment for creating an SE site for computational fluid dynamics, and if you would like SE to add a site for this topic, I suggest you follow the proposal, ask some example questions and upvote five questions because the biggest barrier for getting past the first stage in...
