Disregard previous posts, I had an extra negative sign in there. I've managed to work out the answers, get reasonable solutions and found that they check out overall. Thank you guys so much, this problem has been hell for me all week!

I'm just confused isn't Q=0 in an adiabatic process? So is the circuit an outside heat source then?

First of all I want to thank you guys, I obviously have a lack of understanding of some of this material, but I'm still running into slight issues. The final pressure I'm getting is terribly small(0.026atm), which just seems off, and when I throw it into the other equations I'm getting...

Homework Statement 1, 2, and 3 use the following information: a cylinder is closed at both ends and has adiabatic walls. It is divided into two compartments by a movable, frictionless, adiabatic piston. Initially the pressure, volume, and temperature on both sides are equal and given by P=10.0...

Ah, sorry I guess I didn't realize I didn't explain that. :redface: It was something to do with a Lorentz transform for momentum. I always forget that the same symbols and letters aren't used universally. I thought you were asking for values for each of the letters. I guess that's where I...

And as I said, this is the EXACT problem I was given. This is all I had to work with, which is why I posted it here. But my professor showed me how to do it after I turned it in so it's not an issue now.

Unfortunately, there are no values for anything. I turned the homework in today and my professor showed me how to do it. It was pretty messy.

Homework Statement Show that 1/\sqrt{1-(u'/c)^2}=\gamma(1-(vu/c^2)/\sqrt{1-(u/c)^2}Homework Equations The Attempt at a Solution Since I'm terrible with Latex I took a picture of what I have so far. I'm not sure where to go next or if I'm even on the right track. My professor gave a hint...

Yes, I e-mailed my professor later after posting this and asked him if I was on the right track, to which he said yes. I just felt I was doing something wrong since the expression just kept exploding and I've begun to associate that with me making a careless mistake somewhere. I'd tell you...

Homework Statement r(t)=cos(t)i+sin(t)j+sin(2t)k Find the curvature κ, the unit tangent vector T, the principal normal vector N and the binormal vector B at t=0. Find the tangential and normal components of the acceleration at t=∏/4 Homework Equations T(t)=r'(t)/|r'(t)| N(t)=T'(t)/|T't|...

Disregard this, I was making it more difficult than it was. Problem solved.

forgot to upload diagram

Homework Statement A uniform electric field with a magnitude of 600 N/C is shown pointing in the y-z plane, at 30 degrees from the +y axis and at 60 degrees from the +z axis. This electric field passes through a cube, with each side of length 2.0cm and oriented with faces in the +x, +y, and +z...

Awesome, thank you very much. It's bookmarked for when I inevitably become stuck on another Physics 2 problem :p

Alright I think I FINALLY got all it all. Thank you very much for all of your help. I have a habit of overthinking problems and spending far longer on them than I should. So thanks for giving my brain an enema. Also, how do I use this LaTex, I think it'd be far more convenient for everyone if...
