Protons Definition and 343 Threads

I have been watching videos about the Shroud of Turin. I knew that it was Carbon dated to medieval times. I knew that they were able to produce a 3D image that is not possible with photos. I also knew that linen turns yellow when exposed to the sun...

Statistical mechanics might as well be Klingon as far as I can read it, so interpreting an academic physics paper can be tricky. Still, this paper here https://arxiv.org/pdf/2004.12065 struck me as intriguing. I'm pretty sure this paper is about the innards of protons and neutrons, which I find...

From data of proton-proton collisions at the LHC using the ATLAS detector I have plotted a heatmap of the distribution of satellite clusters (brem and converted photons) around seed clusters (electron/photon candidates without satellites) at (eta, phi) = (0,0). The data I am using is of the...

How much force will it required to pull a quark out of a proton, and how much for to pull a proton out of a atom ?

What is easily seen about how the internal structure of proton is explored is collisions of proton with electrons of high and varied energy. Electrons have an advantage that they are simple particles easy to handle: muons and tauons are short lived neutrinos are hard to aim and detect other...

What would happen if the protons started to have orbital movements with energy gain and loss, changing orbital bands, at the same time as the electrons?

Hello, i was wondering, during the pair creation caused by the collision between a very energetic proton and a target (atomic nucleus) in a particle accelerator, what happens to the very energetic proton after the collision? Is it destroyed, intact, split into quarks or something else? Thank you!

Suppose in a Vacuum with no external influences we have two particle accelerators pointed at each other. They're maximally precise and one fires an electron while another fires a proton. Both the electron and proton have the same amount of momentum such that their x-axis velocity completely...

If we increase the magnetic field, the radius of the particle's circular path will decrease which increases the tangential acceleration. How do I find the tangential acceleration. Do I use derivatives?

Before introducing Special Relativity, a textbook highlights the inconsistency of Maxwell's Electrodynamics and Newtonian Mechanics through the standard discussion about the velocity of light in different frames of reference. A further inconsistency discussed. In some inertial frame of...

In NMR, protons that are near each other exchange energy with each other by photon emission and absorption. Proton A is spin down, and proton B is spin up. proton A emits a photon and becomes spin up, and proton B absorbs this photon and becomes spin down. have the two protons been entangled?

Lets say, in zero gravity space, you have an incredibly precise collider that slams protons and electrons into each other as perfectly as possible such that all momentum is canceled out and the resulting neutron has no velocity relative to the observer. As protons and electrons continue to...

If the nuclear force is many times stronger than the electrical force, why don’t two protons form a stable helium-2 nucleus?

For medium to large nuclei, common sense suggests that protons should not be uniformly distributed inside the nucleus. Assuming the protons inside the nucleus are mobile (but supposing that it doesn't make sense to consider the nucleus a "conductor", in which case all charge would reside on the...

Can you compare the energy loss of electrons and protons due to the radiation they emit? In fact, I want to know which of the two loses more energy when it emits radiation.

One of the main lessons from general and organic chemistry was excess protons in aqueous solutions exist in the form of hydronium ions. However, in biochemistry textbooks, protons are individual in descriptions, for example, of the pumps in the electron transport chain, photosynthetic complexes...

The image given with the problem: I found the original problem too difficult to solve, so I thought I'd make it easier by first considering the stationary proton as fixed in place. However, this too proved to be way more difficult than I expected. Here's the updated diagram I used in my attempt...

Feynman said in one of his lectures that electrons can't just fall down into the nucleus since the uncertainty principal wouldn't let them have a known position and momentum at the same time. The problem I have with this is that protons seem quite happy in the nucleus. Is my objection fair...

First of all, I didn't know whether to pick this subforum or the engineering/compsci one, I understand this might need to be moved to a more appropriate subforum. The general approach is fairly obvious, use implicit method to construct the tridiagonal matrix for Thomas method and solve. However...

I am needing clarification for a concept. I understand that electrons carry a negative charge and that protons carry a positive charge. I also understand that a plastic rod picks up electrons when I rub it with a piece of wool. From the conservation of charge, the piece of wool must have a...

Summary: Finding the KE of a two proton collision that creates Kaons. Given the rest KE of protons and kaons, what is the minimum KE of one proton that can create the two kaons. In high-energy physics, new particles can be created by collisions of fast-moving projectile particles with...

Is it possible to create new protons, or is this ruled out by currently know physical laws?

Hello, my friend says a single proton would be considered an atom and I am saying it would not not. Technically protons are hydrogen ions, and my friend is referencing the definition of ions via WEBSTER -_- Webster says ions are atoms with an uneven number of protons to atoms. Therefore, by...

After mixed, the volume is 200mL I am confused. The mol of H2SO4 is M*V 1M*100mL or 1M*200mL ? Finding the concentration of proton means the Molarity for H3O+ right? mol/volume H2SO4 + H2O -> H3O+ + HSO4- Mol H3O+ = Mol H2SO4?

I'm happy to admit that I am struggling to digest this recent arXiv paper - https://arxiv.org/abs/1904.11974 - but I am interested in whether its reasoning and provisional conclusion seems insightful or merely interesting. My summary of their work is that the researchers consider colour...

Now that I think about this some more, nucleons can get close together if they are traveling at a very high speed. So maybe when the Earth first formed, stuff was moving fast (or at high temperature/pressure) and this forced nucleons together into nuclei? I don't really know what I'm talking...

Assuming that you can create a proton current. For example, the current of ionized hydrogen is analogous to a conductor. Question! Will a magnetic field be created around a conductor with a current of protons? By analogy with the magnetic field of electrons in a conductor.

So first I tried to use KE=1/2 x m x v^2 but then realized I didn’t have the velocity and I can’t figure out a way to obtain it. I then tried to work out the energy using a different equation, W= q x v but that left me with 1.28x10^-14 J which seemed too small. I also then have to calculate the...

For the colourfully-annotated compound above, why aren't the splitting patterns and integrations for the red and blue set of protons "pentet, 6 H" and "octet, 4 H", respectively?

Homework Statement Homework Equations N/A The Attempt at a Solution I am trying to complete the last part of this question, part 5(c). My professor has told me that the form factor $$F(q)\rightarrow1$$ as $$q\rightarrow0$$ but I am unsure how to show this. I believe that $$\lim_{{q...

Does electrons or other particles attracted towards a magnet due its magnetic momentum?

I do not understand the theory of moment of nuclei I read here: http://www.sjsu.edu/faculty/watkins/nuclearmoment3.htm that the magnetic moment of Hydrogen is 2.79284734 magnetons = 2.79284734*9.274009994e-24 joules/tesla =2.59e-23 joules/tesla So if I make to rotate a proton using 150 keV...

If an electron is moving in a circle in a magnetic field, it produces a magnetic field in accordance to the right hand rule. If a proton is moving in a circle in a magnetic field, would it produce a magnetic field in accordance to the left hand equivalent to the right hand rule.

What affect does the phenomenon of "length contraction" have on the shape (e.g. spherical, rugby ball, barbell, donut) of protons accelerated to 0.999999991 c in the LHC?

Hi I need to know if a thin mylar film with deposited ZnS:Ag is capable to detect low energy protons, say 10 keV, emitted in a high vacuum.

Neutron and proton are themselves not composed of mesons, then how do they emit these particles inside the nucleus?

Hi, I was asking how fast is the fastest Hadron ever moved in the large Hadron collider.And most importantly how do they calculate it? Do the calculate it mathematically or with a detector?

Homework Statement As we know in NH3, N full fills its octet with three single bonds with H and a lone pair of electrons and so H. So this molecule is stable. In BF3, F full fills their octets by three single bonds with B but B is unable to fulfill its octet. It got 6 electrons by three single...

Homework Statement According to the Big Bang model of cosmology, the universe has been expanding since some initial time (call it t = 0) when the temperature was infinite. At early times, the temperature T scales as t^1/2 . The current temperature is about 3K. Consider the part of space which...

I'm curious if there is any documented effect along these lines, via EM waves. Hypothetically, all objects have a resonant frequency which will cause them to vibrate when matched. As an example, stone has a resonant frequency per type, its molecules also, atoms also, and I personally theorize...

Homework Statement Hi! So I stumbled upon this simple "plug n' play" exercise in my Physics textbook. Basically it gives you certain molecules/atoms, and tells you to measure the Electric Charge, and its Mass. Pretty simple, but I hit upon some hickups. Anyway, let's get to it: Find the...

Homework Statement A Van de Graaff generator is one of the original particle accelerators and can be used to accelerate charged particles like protons or electrons. You may have seen it used to make human hair stand on end or produce large sparks. One application of the Van de Graaff generator...

I'm not sure if this is the right place for this question., but I'll ask anyways. So in particle accelerators when the protons "crash" particles are created because of the extremely high amount of energy(example of e=mc^2?)? Is that correct? Also, where do these particles come from? The Higgs...

In an effort to understand how an electron and proton attract each other in the QFT picture, I am wondering if there any differences at all between photons (virtual or whatever) emitted by electrons and photons emitted by protons? For instance, do photons from protons have a different spin or...

Homework Statement In a colliding beam apparatus, two beams of protons are aimed at each other. The first proton moves with a speed of 0.82c to the right; the second moves with a speed of 0.86c to the left. Both speeds are measured relative to the laboratory frame of reference. What is the...

Homework Statement In a proton linear accelerator, protons are accelerated to have a kinetic energy of 530 MeV. What is the speed of these protons? (The rest mass of a proton is 1.67 × 10-27 kg.) Homework Equations E0=m0c^2 E=E0/√1-(v^2)/(c^2) E = KE + E0 The Attempt at a Solution Recognize...

I’ve been reading on the physics of how a Magnetic Resonance Imaging (MRI) works from this link regarding the T1 and T2 relaxation time of protons. So far I understand the concept except what they’re trying to explain in the last 2 paragraphs about spin echo. This is what I got from these last...

Is this some sort of issue with color or another quantity that needs to be conserved?
