Homework Statement Let X and Y be two independent random variables with the same probability density funtion over: f(x) = {1/a if x € [0,a] {0 if x=0 Find the density distribution of a) X + Y and b) X*Y Homework Equations The Attempt at a Solution Ok, my...

I have a particle physics assignment due and I am confused as how to read this table. Any help is greatly appreciated

For a nice simple answer, use the fact that force is the rate of change of momentum. F=(mv-mu)/t if you assume that the bullet stops immediately when it hits the wall, then its final velocity is 0. Therefore the force F=mv/t. Although there might be a bit of difficulty in measuring t...

Homework Statement Given an electric potential of Vo*sin(wt). This is applied to a parallel plate capacitor of area S, separation d and capacitance C. The questions are a) What is charge Q on the plates? b) Find the electric displacement current c) Calculate the current in the wire...

ok, I am sorry for not including much. i didnt realize. this is new to me as i said. anyway, i am able to solve and get the wavefunction which turns out to be psi(x)=Asin(kx). and if i did my calculations correct, i think the energy in the 3rd excited state is given by...

Hi, I am new to these concepts and i need help on answering some assignment questions. the question is: a particle of mass m is confined in a 1-d box of width L in the third excited state. a) suppose the width of the box is suddenly doubled. find the probability that the particle remains in...
