Let's say we have a single plate with liquid on both sides rising up due to surface tension. The meniscus formed has a radius of curvature $R$. I'm trying to find the excess pressure, i.e, the pre...
$L=T-U$ Here, $L$ is Lagrangian. T is kinetic energy. U is potential energy. But, what Lagrangian actually is? I know what Holonomic and non-holonomic is. But, I was thinking what the Lagrangian re...
We have place a charged particle of 2C with mass 2kg, 1mm above a current-carrying wire of 1A.The charged particle has an initial velocity of 100m/s The magnetic field of the wire for simplicity w...
Let's first remember how you check that you are at an extremum (minimum, maximum, saddle point) of a normal differentiable function. You do so by checking that the first derivative is zero (plus fu...
Should Earth's moon colonies being deep underground ensure natural heating? By natural I mean "non artificial" i.e. not from "artificial" air conditioning. The question is based on the thought th...
A disk of mass $M$ and radius $R$ is initially rotating at angular velocity of $\omega$. While rotating, it is placed on a horizontal surface whose coefficient of friction is $\mu=0.5$. How long ...
Planet 9 would certainly be "dim", but whether it would be dark according you your definition is impossible to say. Planet 9 needs to be smaller or further away than Pluto, otherwise its gravitati...
The method is correct. when you write $s=vt$, $s$ is the horizontal distance and $v$ is the horizontal component of the initial velocity (and it happens to be that the initial velocity has only ...
In 1970, the USSR began drilling at the Kola Super-deep Borehole. The target depth was 15,000 meters; The stated areas of study were the deep structure of the Baltic Shield, seismic discontinuit...
Starting from the classical osmosis experiment, a U-shaped tube with a semi-permeable membrane, I would like to consider the case when the solute added to one of the compartments (labelled A) is co...
Are questions that are borderline chemistry on topic? Since there is not a Codidact community for Chemistry (yet?), I thought the next best match would be Physics Codidact. In particular I wanted ...
The typical 'most simple' derivation of the gravitational wave equation (GWE) starts by a perturbation of the 'background metric' $\bar{g}$ to get $g_{\mu\nu} = \bar{g}_{\mu\nu} + h_{\mu\nu}$, wher...
Nuclear explosions create electromagnetic pulses which are a hazard to electronics. Would someone a few star systems over from a core collapse supernova be in danger? A quick search turned up onl...
MathJax is enabled in this community, but it is not mentioned in the formatting help. If MathJax guidance is wanted, there is some in the Mathematics Codidact formatting help (at the end). This co...
So as we know energy equals pressure times volume, therefore pressure equals energy divided by volume. The density of TNT is 1.65 and the energy per metric ton is 4.184 GJ. That makes 6.9036 GJ per...
Your basic logic is correct, but you are ignoring some effects. Ultimately you can't have a situation that you could theoretically extract more energy from than exists in the system. You are miss...
Suppose a ferromagnetic material with initial magnetization $M_o$.Is there some specific formula which calculates the total magnetization $M$ as a function of $M_{o}$ and the Curie temperature $T_{...
Why can these Single Vision lenses slow myopia for kids, but not adults? Kids' eyeballs are still growing, so there is opportunity to steer them into growing to a less myopic final result.
What are the SI units of the wavefunction Ψ(x).I know that [Ψ(x)]^2 describes the probabilty of finding a quantum object at a certain quantum state but what about the wavefunction instead?
From my perspective, I can only agree that rudeness isn't exactly ideal. In general, if someone's being needlessly rude or aggressive etc., editing/suggesting an edit that improves the post is a g...
I was thinking for a new category called Book suggestion (not only book suggestion either). Usually, most of Science students like to study Science books (their favorite subject) by themselves. Som...
I have a circuit like this. And, I want to calculate resistance from here. I was following these steps. I was calculating resistance for left side circuit. $$R_1=\frac{2 × 2}{2+2+4}=0.5\Omega$$...
In SE sites, homework-and-exercises question isn't allowed in Physics SE. So, I want to know does Codidact also mark home-and-exercises question as off-topic? I have earlier asked twice question on...
While electrons have positive and protons have negative charge. They should collide and vanish, shouldn't they? No. They have other attributes than just being packets of charge. You have to cons...
The major advantage of Alternating Current is that it can be transmitted to large distances without significant losses, which is not possible in Direct Current. Had economical superconducting wire...
