Thank you. Let me try again. 1. Once Bob's conducts his experiment, upon measurement, the system will collapse into one of its eigenstates which each have a probability of occurring. Since there is a certain probability of each state occurring, and each measurement could possibly result in a...

I have a question on my homework set and I'm not sure the principle behind it: 1. Alice measured an observable F (a matrix) and passed the measured system immediately to another experimentalist, Bob, who is going to measure another observable G. Alice claims that she can deduce the experiment...

I see, thank you!

Thank you very much for your response. With the capacitor's impedance set to negative and the correct answer pops up. What is the rule to determine whether an impedance is positive or negative?

got it! That was the error. The proper equations were this: a(6000) + (a-b)(2000) + 5x - 10=0 -5x + (b-a)(2000) + b(3000) + (b-c)(4000) = 0 10 + (c-b)(4000) + c(2000) = 0 x/1000 = -c Thank you very much!

I see, thank you very much.

Oh I understand that it decreases actually. I had only punched sin (2pi(0.28)) into a calculator and it gave me a positive. Thank you.

Homework Statement Homework Equations R = pL/A The Attempt at a Solution R(a) = 2x10^-4(0.15)/[pi(0.0005/2)^2] = 152.789 [Ohms] It is slightly off. Is there a subtle point that I've missed? Thank you very much.
