Internal Energy/Helmholtz Free Energy Proof
Homework Statement Show that (∂(βA)/∂β)N,V = E, where A = E - TS is the Helmholtz Free Energy and E is the Internal Energy. Homework Equations A = E - TS dE = TdS - pdV + ΣUidni β = 1 / (kBT) The Attempt at a Solution (∂(βA)/∂β)N,V = (∂/∂β) * (βE - βTS) (∂(βA)/∂β)N,V = (∂/∂β) * (βE -...- mobwars

What are some unique physics-related tattoo ideas?
Although simple, a good idea (and one that I'm considering jumping on) might be to have the Newtonian equation for universal gravitation tattooed upon your shoulder in reference to the famous quote from Sir Isaac Newton himself.- mobwars

radius MUST be less than 62 right? EDIT: and indeed. lol.- mobwars

Hmm...what equation did you use? I used (theta)=tan^-1(v^2/rg)- mobwars

Circular Motion, Banked Turn Without Friction
Everything else is going smoothly, as I outlined every other process that I would need to go through for the later calculations. Pretty insane angle for the banked turn though...59.8 degrees. Certainly would be interesting to try and drive on that.- mobwars

Circular Motion, Banked Turn Without Friction
Yes, okay thank you. That makes so much more sense. This seems like a problem that you have to be able to visualize more than anything else, and the way you worded that make it extremely clear. Thank you thank you thank you. Have a great night!- mobwars

Circular Motion, Banked Turn Without Friction
Here's what I have thought of as far as maximum radius is concerned. If the space above bubba's is 18 m and the space beside bubba's is 18m, then the two dimensions make a triangle (in the form of a^2+b^2=c^2) (18+x)^2+(18+x)^2=c^2. Am I on the right track?- mobwars

Circular Motion, Banked Turn Without Friction
Okay. I analyzed the figure and I'm still a little confused. The maximum r would be found by seeing that the dimensions make an imaginary square 18m x 18m. I'm just so lost. I know this isn't for just getting the answer, but I've been staring at this picture for past hour. I know I'm over...- mobwars

1.Traffic travels north on Newton blvd and turns east onto the road einstein way. The speed of the traffic traveling north and east is 55 mph (24.6m/s). The banked turn must fit within an area (shown in the picture attached). The illustration is not drawn to scale. You are to design an exit...- mobwars
