I found this part of forum the most relevant to this theme so excuse me if I missed. This year I'm doing a high school summer project related to quantum mechanics. Anyway I'm using finite difference method to solve Schrödinger equation. Before starting to work on a project I decided to get some...

I think you are absolutely right . I got confused about the marks how dumb. THANKS ! I got this for the final solution: $$Q(t)=Q_0\cdot e^{-t\frac{s}{e_0}}$$ I don't think so because it's problem for high school students and they usually don't study Maxwell's equations. I've just finished...

You know that is work A[J]=F[N]*s[m] => J=kg* (m/s)^2 From here you can see that if the c is in m/s them mass must be in kg.

[Note from mentor -- this post was moved here from another forum] Hi, I ran to this problem today and i try to solve it but i can't complete it so if anyone can help me :) Sphere has a charge Q0. Inside the sphere is vacuum and outside the air. Consume that air has small non zero conductivity...

Ok, if it says that change of internal energy is part(for example 1/3) of TOTAL work executed over system(body). Does it mean that is TOTAL work indeed sums of every single work(mechanical work+internal energy change+...) ?

Can anyone answer ?

Ok thanks, then i have new question, If it says that is change of internal energy 1/3 of total work, in total work i should count sums of every energy changes ?

Hello, i have one question about work, Does work must be mechanical ? or we can change of some energy that is not mechanical (like internal or chemical) call work ?
