Beer related physics, for a undergraduate project

hey all, I am not using the template, bc this isn't a standard problem.


I am doing a few beer related physics tricks for my phy 252 research project at Arizona State, and I need help with one in general.



Why does, when you hit two beer bottles together (one on top of the other) the bottom one overflows? Now I know that the CO2 is released when the beer hits the bottom of the bottle, causing a jump in pressure, but i really want to know why. I need an equation here, not PV=nRT or W=p(V2-V1) or any of the regular thermodynamics equations. I need something specific, and I've been racking my brain trying to figure it out but i cant. Secondly another thing that i need more help explaning is why doesn't the top bottle release pressure, shouldn't there be enough vibrations between the gas molecules to have the same effect?

Thanks guys!

Thread 'Direction of the magnetic field of an oscillating charge'

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
