Can someone explain this formula to me?

In principle I understand everything, but the electric force (Fel) says:

E Γ— q = u / d Γ— q because E = u / d but.

The final equation then gives d / u.

In my book it says:

The force that is exerted on a body in an electric field is proportional to its test charge q. The quotient F / q is independent of q and is therefore a measure of the strength of the electric field in every point in space.

But q is also in the formula. Then why is it independent?

We have that in class right now. A ball is on a thread between the plates of a capacitor. My question is, can you calculate the electrical force in the capacitor (Fel) without the voltage?

Didn’t give that in the task, the formula is F = Q * U / d. Someone has no idea how I usually come across “Fel”?

In my book it says:

Field lines are always vertical on conductive surfaces: The mobile charge carriers on the surface are shifted until the force no longer shows any components parallel to the surface.

Can someone explain that to me visually: D Or explain the process normally?

what differences are there between these formulas:

2H2 + 02 = 2 H2O and H + O = H2.

I know the principle of an equation of atoms that react with each other to form ions or electron pair bonds, if necessary (so I understand the 2nd equation). What I don’t understand, however, is the 1st equation, where suddenly there is a 2 in front of the H. Logically I cannot derive this formula myself. I create the!

Formula occasionally using Lewis notation.

But we can know if there is a 2 in front of the H at the beginning and how you can derive the 2nd formula. (Are there also certain techniques such as the Lewis shrine style)

It says that I have to take the first equation * 2 and the second * (- 3) but why? I do not understand that.

PS: Can someone please explain to me which method I should use for which equation, because I always find it difficult and just try it out.

In physics, we have the formula s = 1/2 * a * t ^ 2 when calculating the distance for a uniformly accelerated movement. Unfortunately, I don’t really understand the derivation of this equation. Maybe someone can help me?

I do not understand this formula, neither what it is supposed to say nor how it is used.

Please help me! πŸ™

Thank you in advance πŸ™‚

Below you can see exercise 6. I don’t understand the following about it. Why is it assumed that Fg = Fel is only because the piece of cotton is floating. I how I don’t understand why sat is exactly what that is. It would be nice if someone could just explain that to me😊

So Wikipedia says something about the recoil principle. I don’t understand this though. Can you please explain that to me?

Hi folks, I just have to write a math thesis about complex numbers, and have understood the derivation of the Euler formula and also what the equation basically wants to say. However, in Wikipedia (and also in other sources), instead of the argument (iy), ‘I alpha’ is used to express the equation with angles. So you should use an angle for alpha, but e.g. in the case of identity, pi is used instead of an angle.

How do you have to use that now, with a radian measure or what? There is a formula in the appendix, it would be nice if you could tell me what the formula says and how to use it, preferably with a calculation example, then it will be clearer ^^ Thanks for the help in advance.

Good evening, I have a little question:

in physics we should derive the formula: Uh = B * v * b.

The approach is of course clear: Fel = Fl (Fel = electric field force; Fl = Lorentz force)

After that there is this formula: 1) e * E = e * v * B.

This results in: 2) Uh / b = v * B.

My question now: how do you get from Formula 1) to Formula 2) ?

Thanks in advance!!

Hey, I’m just going through math again, because we’re on the subject of stochastics, which I don’t really like. Actually, I understood almost everything in this area (tree diagram, four-field table, Laplace, etc.) but I just discovered a “funny” task:

I understand the principle of tree diagrams, but I believe that the pq formula must also be used here because there is still an unknown x there. However, this is not a quadratic equation, which is why I cannot use it. Does someone understand the task?

Formula can be seen in the picture. It would also be helpful what the er21 with arrow stands for and how I can imagine the vectors in this equation.
