    Schools Questions about certain SUNY schools

    Hello, I was wondering if anyone has any knowledge of the physics departments at Suny Binghamton, buffalo, or geneseo. I got accepted to all and was curious on hearing how the department works as a whole, research opportunies, etc. Thanks you.

    Is it normal to not understand any homework questions?

    Hello, So I'm in my last semester at my local community college and I'm taking Modern Physics. The class is cool and all, but the material is very hard to grasp. Furthermore the homework questions, (to me), are nearly impossible to complete. It takes me close to thirty minutes just to...

    Using u-sub for inetgral(x^4sinxdx)

    So I came across a problem that said to use u-sub to solve: integral(x^4sinxdx) But the only way I could think of solving it is by the tabular method (or by parts.) I'm not asking in the sense of a homework question I'm just curious to see what I substitute u for in this problem. Thanks.

    Determining effective nuclear charge

    Homework Statement The 3s state Na has an energy of -5.14eV. Determine the effect nuclear charge. Homework Equations I believe you have to use: En=-[(13.6eV)Zeff^2]/n^2 The Attempt at a Solution So since Na is in the 3s state, I think n=3. So: -5.14eV=...

    Depth of a finite square potential problem

    Homework Statement Consider a finite square-well potential well of width 3.00x10-15 m that contains a particle of mass 1.88 GeV/c2. How deep does the well need to be to contain three energy levels? Homework Equations The Attempt at a Solution I think I have to use the formula for penetration...

    What is the Probability Density for a Wave Function?

    Homework Statement A wave function ψ is A(eix+e-ix) in the region -π<x<π and zero elsewhere. Normalize the wave function and find the probability of the particle being (a) between x=0 and x=π/8, and (b) between x=0 and x=π/4. Homework Equations The Attempt at a Solution So to...

    How to determine where the B feild starts

    Hello, This is kind of a simple question but if an EM wave is propagating in the positive x direction and the E field starts in the positive z direction, how do you figure out if the B field starts in the - or + y direction? Thanks

    Double Integral Problem: How to Evaluate ∫1 to 4∫0 to y(2/(x^2+y^2))dxdy

    Homework Statement Evaluate: ∫1 to 4∫0 to y(2/(x^2+y^2))dxdy Homework Equations The Attempt at a Solution So I know you have to spilt it up and do the dx integral first: ∫0-y(2/(x^2+y^2))dx Now this is where I don't know if I'm doing it right, I moved the 2 outside the...

    Transferring to a UC school from out of state.

    Hello I was wondering if anyone who knows about UC schools (especially Santa Barbara), could tell me what my chances are for transferring there. -I am however out of state, I go to Hudson Valley Community College in New York. -I have a 3.33 overall GPA and a 4.0 major GPA (Physics)...

    Quantum Mecanics unifing with General Relativity in 5D

    Hello, I didn't know where to post this since it deals with both topics, but I thought here would be the best choice. So I have a research paper I have to do in Physics this semster and its about me researching somebodys research they're currently doing or just finshed. So I've been looking...

    Heat with relation to work or energy

    So if an object starts from rest 1/2 metre away from the object, I would first find Ug then KE right as it hits the object and assume all the lost energy is released as heat?

    Heat with relation to work or energy

    Hello, I know this seems silly to ask, but how could I figure out how much heat was given off when I know the force of an object hitting another?
