Thanks for clearing that up. The instructor covered only homogenous problems, and when I ran into one of these I was not entirely sure how to solve it with series.

Homework Statement y'' + y' + y = 1 + x + x2 Homework Equations y = Ʃ CN*xN N starts at 0 y' = Ʃ N*CN*x(N-1) N starts at 1 y'' = Ʃ N*(N-1)*CN*x(N-2) N starts at 2 [b]3. The Attempt at a Solution [/] I know how solve the equations...

Thanks! I was forgetting something. lol. I also noticed I made another error when I copied it over from my work...Yeah, I'm frustrated with this one and all the others problems that are asking about the magnetic field. (a) What is amplitude of the induced magnetic field a distance 13 mm from...

Wow, no one. Well, at least I am not alone! lol

Anyone? I know, its a toughy, but I figured a second pair of eyes could point me in the right direction.

Homework Statement Parallel plate capacitor with circular plates with radius of 26mm and a plate separation of 6mm. A sinusiodal potential difference is applied across the capacitors plates with Vmax = 170V at a frequency of 60Hz. 170sin(2*pi*60Hz*t) Homework Equations V = ∫E∙dl = El (l...

I think I just answered your question! Thanks it makes a lot more sense now.

I know that the magnetic field is uniform with in the solenoid near the center, and that would mean that the loop will see what ever its area is.

Hmmm. I am not entirely sure. The equation for magnetic flux calls for it, but I think that is for the solenoid itself.

Help?

Need the picture?

Homework Statement A solenoid has length L = 20 cm, radius 6 cm, and N1 = 4500 turns; its axis coincides with the z-axis. A circular conducting loop containing N2 = 11 turns of radius a = 1 cm is centered inside the solenoid; the plane of the loop makes a 30° angle with respect to the z-axis...

Thanks for the help! I see if i can get it in a bit!

Yes, it is P=V*I(t). So, when I find the total current over time I can just plug it into that!

Do I just inetrate (V/R)*(1-e^(Rt/L))? Its the only thing i can think of now that will be of any help. I tried to figure this one out from the hints you gave me but no luck.
