Homework Statement Problem 1 If all of the particles shown in the figure are electrons, what is the direction of the magnetic field that produced the indicated deflection? http://session.masteringphysics.com/problemAsset/1013281/5/jfk.Figure.24.Q35.jpg Choices Up (toward the top of the...

Thanks for trying to help me. Hm...let me try and be a little bit more clear. What I was trying to say, is the light passing through a single filter or two filters, is that light partially or completely polarized?

So in that case, would that mean that one filter has complete polarization and 2 filters is partial polarization?

Can anyone explain to me the difference between partially and completely polarized light?

Homework Statement I just have a few of questions about light polarization. We never discussed polarization in class, so I am slightly confused on a couple of questions. For the Experiment we used polarization filters. If I understood the difference between partially and completely...

Alright, thanks for the help. I shall try again later after reviewing the material.

1 v = 1 j/c so... 40 v = 40 j/c 40 j/c

40v?

Sadly, I still do not understand. This entire chapter confuses me.

Homework Statement http://session.masteringphysics.com/problemAsset/1020825/7/jfk.Figure.21.P56.jpg A proton's speed as it passes point A is 4.40×10^4 m/s. It follows the trajectory shown in the figure. What is the proton's speed at point B? Homework Equations Knowing this would be...

Alright, thanks for the help. I have the correct answer now. I have the rest of the problem worked out as well. Man...I wasted so much time on this problem when the only major mistake I made was the negative sign. Normally MasteringPhysics tells me if the sign is incorrect...

This time I tried the other equation... 1800 = U / (2*10^-9) 3.6*10^-6 = U still wrong. *edit* I made my post while you made yours...>_> Let me look into your post*

Homework Statement Part A - (Already solved) The electric potential at point A is 1800V. Part B - What is the potential energy of an electron at point A in the figure? Point A is .01m away from a charge of +2nCHomework Equations V=Uq U = (Kq1q2)/rThe Attempt at a Solution I think the...

Hm...perhaps this equation v^2 = vo^2 + 2a(X - Xo) *edit* Yup...that would be the correct equation. Thanks for the help Doc Al.
