Yeah, if I did this question I would naturally distinguish between those two but I never asked myself why that is fundamentally the case.

Yeah. I solved a lot of integrals. I know I need to distinguish between ##V## the volume and ##V## the integration parameter. I just never asked myself why you fundamentally have to do it.

Yeah yz is the constant cross area

Well I am going from x1 to x2 but it's all multiplied by yz

So, I volunteered to run a seminar to first year students in my college. They got a question like this for homework recently and a lot of them made a mistake in the calculation. I am not asking for help with the question itself because I know how to do it. However, a lot of students made a...

The question is taken from An Introduction to Modern Astrophysics by Carroll and Ostlie. I did manage to do the entire question and plot the relevant graphs but I just want to to investigate a bit more. For example I want to look at how the graph would like in the case of the Sun. I don't know...

Thank you. I will look into it.

That's alright. I'll definitely keep that in mind when choosing a project. Thank you for the help.

Yes, but I reckoned there would be no point in doing a project on a topic I know cause I'm not learning anything new that way.

Hi guys. I'm a third year physics student. Next year I'll be in my final year. I'm interested in studying fusion in the future. Unfortunately I have not done plasma physics as part of my degree so I don't know much about it yet. However I'd like to do an internship abroad this summer. Ideally I...

Summary:: I am looking for topics to give a presentation on. Hi everyone. If this is in the wrong section feel free to move it. Anyway, as part of our lab course, on top of doing experiments we will also have to prepare a 20 minute presentation on a chosen topic on physics. This is not like...

Ah okay, so all the momentum will go straight into the plates. I think I understand now. Thanks a million.

Okay that is starting to make more sense now. Just need to clarify a few small things. There is no magnetic field in the question. Therefore the Poynting vector is zero everywhere. So the volume integral of our Poynting vector will be zero. Therefore the electromagnetic momentum at any point in...

Region II is gaining z-component of momentum and region I is losing z-component of momentum

Negative
