Equation 1 of my "Relevant Equations" is how I got H2. I just inserted B2 into the equation. And thank you! That link makes a lot of sense. I was wondering if I was going in the right direction in terms of subtracting the vectors to get zero. Because from the link you posted, I need to find...

Homework Statement The xy-plane serves as the interface between two different media. Medium 1 (z < 0) is filled with a material whose µr=6, and medium 2 (z > 0) is filled with a material whose µr=4. If the interface carries a current (1/µ0)ˆy (y- hat) mA/m, and B2 = 5ˆx (x-hat) + 8ˆz (z-hat)...

Oh so I shouldn't have taken it out in the first place then? That makes sense thanks! Other than that, am I missing anything else?

Homework Statement The harmonic oscillator's equation of motion is: x'' + 2βx' + ω02x = f with the forcing of the form f(t) = f0sin(ωt)The Attempt at a Solution So I got: X1 = x X1' = x' = X2 X2 = x' X2' = x'' ∴ X2' = -2βX2 - ω02X1 + sin(ωt) The function f(t) is making me doubt this answer...

whoops, I meant Sx is represented as ħ/2 [[0,1],[1,0]]. I was under the assumption that the ket |+> = [1,0] and that the ket at the bottom didn't affect it. From your response I guess, it does affect it. Also isn't the dirac representation just the bra and ket? <+|A|+>

Homework Statement I have to find the matrix system of Sx, Sy , and Sz using the given information: 190899[/ATTACH]'] Homework EquationsThe Attempt at a Solution for attempting Sx: Ignoring the ket at the bottom, I would get Sx|+> = +ħ/2[[0,1],[1,0]] but my question here is, does the ket at...

I 'm sort of getting it now. Since the first circuit is in series, lowering the resistance increased the deflection. Using Ohm's law, I =V/R, the meter indicated more current was able to flow through. For the 2nd circuit, using kirchhoffs law, increasing the resistance by a little bit...

I'm not really sure what you mean but this is from a lab and for the series circuit, full scale deflection of the meter is required. The parallel circuit, one-half scale deflection of the meter was required, which is why the parallel resistor was added.I originally used the parallel circuit to...

Homework Statement I have to prove that RI = RSRP/(RS - RP) by circuit analysis. The Attempt at a Solution [/B] So I tried to create a system of equations to do this: For the first circuit using kirchhoffs rules: V-IA(RS + RI) = 0 [1] For the second circuit: V-IBRS - IPRP = 0...
