Homework Statement So a kaon moving at some speed in the +x direction spontaneously decays into one pion and one anti-pion. The anti-pion moves away with velocity of 0.8c, and the pion moves away with velocity of 0.9c. Mass of kaon = 498 MeV/c^2 Mass of pion/anti-pion = 140 MeV/c^2...

I figured I needed that relationship already. I was just unsure how to visualize it and needed explaining of the problem. The relationship was c = v(deltaT). Simple enough but I just needed to understand the problem first.

Phase difference between clocks with distance Homework Statement Derive Phase difference between clocks with distance Homework Equations I honestly don't understand how this equation ΔT = vD/c2 is derived/figured out. The Attempt at a Solution We haven't covered Lorentz...

Homework Statement Finding error in kinetic energyHomework Equations K = \frac{1}{2} m v2The Attempt at a Solution Measured mass and velocities have errors in them. So we have to use derivative method to calculate uncertainty in KE which is to find the square root of the derivatives of K...

Ahat and Bhat are hermitian operators, yes. But (Ahat -/+ iBhat) is not hermitian. I think I understand but not sure. We have to take the complex conjugate to show that it is not hermitian. So (iBhat)* is (-iBhat). I was wondering if there was more to that step than what I am thinking...

Homework Statement Linear combination is \hat{A} + i\hat{B}. It's given that it is not Hermitian already. Homework Equations ∫ψi * \hat{Ω} ψj = (∫ψj * \hat{Ω} ψi)* The Attempt at a Solution ∫ψi * (\hat{A} + i\hat{B}) ψj = (∫ψj * (\hat{A} + i\hat{B}) ψi)* I chose to work with...

Homework Statement Calculate the mean square displacement x2 of the particle from its equilibrium position.Homework Equations ∫ from -\infty to +\infty of Nv2 * Hv(y) * e-y^2 dy Since y=x/\alpha, \alphady=dx yHv = vHv-1 + (1/2)Hv+1The Attempt at a Solution...

Homework Statement A box is being dragged across the floor with a rope that is h distance above the floor. The coefficient of friction is 0.35. The box is 0.50m high and 0.25m wide. Find the force that just tips the box. Homework Equations Ff=uMg=3.43m/s2M Fg=Mg=9.80m/s2M...
