Homework Statement Two capacitors C1 and C2 and a resistor R are all connected in series. At t=0, a charge Q1 resides on C1 and a charge Q2 on C2 (Q1 > Q2; C1 < C2), and the positive plate on C2 is connected to the negative plate on C1. a) In a first experiment, the positive plate on C2 is...

Homework Statement start with the wave function \Psi(x,0) = Ae^{-cx^{2}}e^{ikx} where A,c, and k are real constants (and c is positive) i) Normalize \Psi(x,0) ii) Determine \Psi(x,t) and |\Psi(x,t)|^{2} Homework Equations The Attempt at a Solution I normalized it to get...

try using the template provided. You'll need to show an attempt at the solution to get help on physics forum.

listen to Gneill, 200J is not the correct answer. Remember, you're trying to the find the work done by the force that is being applied to the crate. Determine what that force is and it should be straightforward from there.

yes, putting gravity into consideration will allow you to get the answer you are looking for. What is the force of gravity on the hammer stake system and therefore what is the net force acting upon it?

ok, so just treating this as an infinite square well problem, I get E_{n}=\frac{\hbar^{2}}{2m}\frac{(n-1/2)\pi}{2a} and \Psi_{n}=A_{n}cos(\frac{(n-1/2)\pi}{2a}x) A_{n}=\sqrt{\frac{1}{2a}} now when you say represent the initial wave function as a superposition of the stationary...

ok, so doing that I just get E_{n}=\hbar \omega_{n} For this question though, it seems like the prof keeps specifying that we are just considering the initial wave function at time t=0. For the next part, we're supposed to consider if the well is doubled in width, and find the energies under...

Homework Statement Consider a point particle of mass m contained between two impenetrable walls at +/- 2a. The potential V(x) between the walls is zero. Assume that at time t=0 the state of the particle is described by the wave function \Psi(x) = A\frac{1+cos(\frac{2*\pi*x}{a})}{2} for...

hello friends. I am currently in my third year of my bachelors of science in honors astrophysics, and after some consideration, I have decided that I want to go into aerospace engineering. Up until recently, my plan was to eventually get a Ph.D and go into a career of research. However, I've...

ok, I wasn't sure if the system was allowed to reach equilibrium or not.

Homework Statement Calculate the change in entropy when a lead bullet of mass 10 grams traveling at 500 m/s hits a very large volume of water. Assume that the bullet was initially at 150 degrees Celsius and the water was at 25 degrees Celsius. Homework Equations K=\frac{1}{2}\,{{\it...

too late, already turned in the assignment. However, I'm pretty sure the light incident on the first polaraizer would be 50% transmitted (since the incident light is natural light with no specific polarization). Without the sugar, no light would go through the polarizer since their axes are...

Homework Statement A glass vessel is placed between a pair of crossed HN-50 linear polarizers, and 50% of the natural light incident on the first polarizer is transmitted through the second polarizer. By how much did the sugar solution in the cell rotate the light passed by the first...

k, so I changed the E function to Cartesian coordinates. So in the overlap I got: \vec{E}=\frac{\rho*d}{3*\epsilon}*\hat{i} where d is the magnitude of \vec{d} And this is under the condition that \vec{d} runs along the x axis.
