Doesn't anyone exist?:smile:

I think an error could be to read the diffraction angle. Because people may read different angles, albeit with slight differences. And because the diffraction angle is related to the wavelength, can affect it.

Yes, I am familiar with diffraction patterns and its theory. No, this is not a school work question, it is a personal question, otherwise I would have sent the question in the relevant section.

In a diffraction grating experiment, what can be the sources of error and also what effect do these sources have on the unknown quantity (wavelength) in the experiment?

Table: To solve, using the conservation of energy: E0=(m(deutron)+m(16O)-m(17O)-m(p))c^2 so: E0=(2.014+15.994-16.999-1.008)931.5=0.93 MeV. so using the conservation of energy: 14.95+0.93=16.62+0+E' E'=- 0.74 MeV But the energy sign has become negative. I also calculated for the first excited...

no

I don't know. This is the question our professor asked us without explanation to think. What is the reason that it is a vector?

Why is the action a scalar? Please explain.

ok thanks

A similar formula was stated by our nuclear professor, but with the difference that there was b instead of c. So I thought in this case b = c

My data is as follows:

My final result is as follows: 4*pi*R^2 (1+ε+ (7/5)ε ^2+ (36/35)ε ^3 +...) Which has a bad difference with the result of the book.:oldconfused:

In "An Introduction to Nuclear Physics by W. N. Cottingham, D. A. Greenwood" for the surface area of an oblate ellipsoid, the following equation is written for small values of ε : The book has said this without proof. I found the following formula for the desired shape: No matter how hard I...

I understand now by your good example. Thankful.

I'm still confused. For example, in 'Introduction to Elementary Particles by Griffith', for relativistic collisions, the center of momentum frame is introduced to solve problems. But isn't the center of mass frame appropriate in relativistic collisions?

In special relativity (especially relativistic collisions), is the center of mass frame as useful as Newtonian mechanics?

What does the phrase “Due to Lorentz invariance, only the Higgs particle can have a non-zero expected value in a vacuum” mean?

Yes. I did not pay attention to it. 😕 I thought the exercise was solved!☺ 👍🙃🙂

I came back.:smile: I still have a knot in understanding this exercise. :frown: Now the values are almost equal. That is, the potential difference is equal to the mass difference. What exactly does this mean? That is, how do you analyze this?

Yes, the result is exactly the same. I got the previous formula. Thank you and those who guided me in this exercise.

The results of this way should be the same as the previous way, right?

Do I have to use both electric fields? That is, I have to use both the electric field inside the sphere and outside the sphere ?

After equalizing the units, the mass difference is almost the same as this number. Thanks for your guidance

Using the relation sent here and the following data, I obtained a value for the electric potential energy of the proton, which is: 1.6 * 10^ (-13) J R= 8.7 * 10 ^ (-16) m k= 9 * 10 ^ (19) Nm^2/c^2 Q= 1.6 * 10 (-19) c What does this number say?

Nothing. I do not know exactly what to calculate. All I know is a relationship to potential energy. Suppose I got it, what does it have to say and how does it explain the mass difference?

So we can not explain the mass difference in this way?:frown:

Suppose I get a number for potential energy this way. How can this number explain the difference in mass to me?🤔

Regarding the potential energy of a charged sphere, I know the following relation: U = k(3/5)((Q^2)/R) But I do not know how to use this to solve.

yes

Im a physics student and this exercise was given to us by a professor of particle physics.

Regarding the potential energy of a charged sphere, I know the following relation: U = k(3/5)((Q^2)/R) But I do not know how to use this to solve.

I asked for guidance, not a complete answer. If someone can not guide, no problem.

i don't know

I do not really know the relationship between potential energy and mass difference. Isn't the difference in mass of protons and neutrons due to their quarks? (the neutron is made of two down quarks and an up quark and the proton of two up quarks and a down quark.) Please help.

thanks🙏

I do not know its sort. Suppose it is inside a particle accelerator.

I did not mean spontaneously. Does it not emit radiation when the electron is accelerated?

Electromagnetic radiation

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.
