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...
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...
In my Physics Codidact profile I am getting that I got 1 downvotes. I am not sure if I asked a question earlier in which I got 1 downvotes. In my current posts I don't have any downvotes or upvot...
$$L'=\frac{m}{2}(a\dot{x}^2+2b\dot{x}{y}+c\dot{y}^2)-\frac{k}{2}(ax^2+2bxy+cy^2)$$where a, b, and c are arbitrary constants but subject to the condition that $b^2 − ac \ne 0$. What are the equat...
If a signal has a analog component then it analog regardless of if it has a digital component.
In signal processing, are signals modeled in only one way (digitally or analogously) or are there some signals which can be modeled in both ways?
This gravitational field we move inside has some distance L after which it becomes 0.Before L it is just like any gravitational field. Suppose we move inside that gravitational field.The accelerat...
The universe could possibly wrap back onto itself, or it could be in infinite flat space. Imagine the difference between being on an infinite plane, or on the surface of a large sphere. In both o...
We know that electrons always repel electrons. But, if somehow they collide, then what will happen? I found a related question of above one in Quora. An incoming electron can instead make them ...
Why abilities don't show in every user page? Take a look at @Mithrandir's profile according to his profile he doesn't have any ability. But, I don't think that he doesn't have ability. I was checki...
Magic.. :D The question was reopened but, showing closed instead of reopened (It should show last_activity according to code). question link
Using imaginary magnetic charges (usually called magnetic monopoles) to solve for forces between two magnets doesn't make sense. Even if magnetic monopoles existed, what exactly do you envision do...
In my notes from University the reason a material can exhibit superconducting properties is at really low temperatures electrons form Cooper pairs of which the electrons of the Cooper pairs have lo...
Edit: While this specific case isn't reproducible, there is a broader problem. This section is sometimes not showing up for people with moderator privileges, on some communities, and I don't yet k...
