Homework Statement Suppose a third slit of the same width were added halfway between the original two slits. (the original two slits were a distance d apart). When there were just 2 slits, the point C was the center (a principal max), point Z was the first maximum after C, point Y was the...

Wow, thank you so much for your very, very helpful response PeterO! I really appreciate it. Here is what I have gathered for Part A, based on that explanation A. The magnetic field in the magnet points downwards (because the magnet inside has a magnetic field pointing north). When the coil is...

Homework Statement A very strong magnet is suspended by a non-magnetic thread. A student forms a loop out of a wire attached to the Pasco 750 Interface as shown on the left. During a half second interval, the student moves the wire loop until it is below the magnet as show a) Describe...

Oh ,that's right! I meant integrated, sorry. Wait, but my answer guide says -27 & 1/3 V and the sum of my answers is −11&1/3 V ? So, how do I got from my integration to the -27 & 1/3 V? I tried just adding and, as you saw, got −11&1/3 V which was incorrect

Homework Statement The electric field in a region is given by E=2x^2 i +3y j where the units are in V/m. What is the potential difference from the origin to (x, y) = (2, 2) m? Homework Equations E = -gradient of V The Attempt at a Solution - derivative of the x-component: 2/3...

Oh, I see what you mean about how it splits up! Ok, got it. My question is, how do I know... how it splits up? IE how much goes to Runknown and how much to R1? Is the sum of their currents = total?

Homework Statement In the circuit in the figure below, the reading of the ammeter is the same when both switches are open and when both switches are closed. What is the unknown resistance R? (Let R1 = 103 Ω, R2 = 279 Ω, and R3 = 46.0 Ω.) Homework Equations Adding Resistance in Series: R1 +...

Yes, I see how Area vector could be in either direction. If I had chosen it to go to the right, then for part a) my answer would be negative, and part b) positive. ? Is the reasoning for part c correct? I guess I just want to make sure that that's how it works! Also, thanks for the input with...

Hey everyone. Having a bit of trouble with a 4-part question. So I thought I'd post here, if someone could check the first 3 parts and perhaps help me with the last part, I'd really appreciate any feedback! Thank you so much! :) Homework Statement a) A circular loop is held to the left of a...

Oh! Got it, so, I believe this is now correct: the electrons in the aluminum rod consolidate near the end away from the teflon rod, which they can do so because aluminum is a conductor (and they want to because both the aluminum and teflon are negatively charged, thus repelling each other)...

Hello, Just wanted to check my some of my reasoning to these. If anyone could confirm if these answer I got are right (or point me in the right direction if they aren't!) I'd really appreciate that. Thanks! 1. Homework Statement (No Relevant Equations, real, & Attempts at Solutions are...
