Homework Statement
A cylinder with a frictionless piston contains 0.05 m3 of gas at 60 kPa. The spring holding the piston is now in tension. The cylinder is heated until the volume rises to 0.2 m3 and the pressure rises to 180 kPa.
Assuming no losses in the system, and the force on the...
I conclude that I am either wrong, or that <p> = 0. I'm inclined to the former, but the latter makes sense, because if I was integrating around the origin (say, from -5 to 5 instead), it would cancel.
Homework Statement
Given the wavefunction, \psi(x) = Cx for 0 < x < 10 and \psi(x) = 0 for all other values.
What is the normalization constant of C? I got \sqrt{3/1000}.
What is <x>? I got 30/4.
What is <p>? Here is where I'm confused.Homework Equations
