    Work in adiabatic process

    Wow reading what you wrote made me realize the answer lol thanks!

    Work in adiabatic process

    Thanks for your help! i is an integer I think it's for any adiabatic system...i'm not too sure actually

    Work in adiabatic process

    Homework Statement My textbook says that W = i/2Δ(pV) for an adiabatic process. I don't understand :S Homework Equations W=∫pdV The Attempt at a Solution

    Ultrarelativistic approximation

    I think you might have an extraneous β here, but thanks a lot!!! I get it now :)

    Circle and Ellipse

    So you mean the end of the ellipse closer to the other focii? Also I posted this here because it was in the context of elliptical orbits but now i realize it is more of a math question ;)

    Ultrarelativistic approximation

    I read that when v≈c, sqrt(1-β2) = sqrt(2*(1-β)). How do you show this mathematically? I have no idea. Thanks! :)

    Circle and Ellipse

    hi Yukoel, no, i don't seek a mathematical proof. i just want to understand the statement. I still don't really understand... what do you mean by it "states constraint of the tangency condition"? thanks for your help!

    Circle and Ellipse

    What does it mean when one says that "A circle and an ellipse with a focus at the circle’s center can touch each other only at the longer axis"? Can't you, by varying the size of the circle, make it intersect the ellipse in a variety of ways? Thanks! :)

    Equation of motion for coupled oscillators

    So are the "a"s just constants? x is the displacement from equilibrium right? Thanks! :)

    Phase of Wave

    Thanks Tiny Tim! i totally get it now :)

    Phase of Wave

    The phase of a wave at (x,t) is a0cosϕ = ℜa0eiϕ. Where did this come from? I know that the phase of a wave is given by ϕ = kx−ωt+ϕ0 but then I am stuck. Please help! Thanks :D

    Higgs particle is 'found'

    there'll be other things to discover; you'll still get to work at ATLAS :)

    Electron in box considering effects of gravity

    Okay En=n2∏2ħ2/(2mL2) Problems 1. Do we just set n = 1 since when know the particle is near the ground? 2. The equation is derived for when potential energy is zero (when kinetic and potential energy are equal). Is En going to be E in our case? So we get the equation below?* 3. We don't know L...

    Electron in box considering effects of gravity

    Oh! Well then Δp = \sqrt{2m(E-0)} - \sqrt{2m(E-mgΔx)} and we substitute this into ΔpΔx≥h/2∏ to find Δx. What is E though? Many thanks! :)
