Could someone explain the rudimentary parts of this model? Also, I don't understand how the Electron Configurations work for this. They seem to follow a particular pattern for certain elements and another pattern for other elements. Or is it the same for all elements? Here's what I think I...

Okay so... Problem 2b: i. T3-3mg=-3m(g/3) T3-3mg=-mg T3=-mg+3mg T3=2mg ii. T1-mg=(mg)/3 T1=(4mg)/3 iii. T=I(alpha) I=Torque/alpha alpha=(g)/(3R) Torque=T3-T1 I=(2mg-(4mg/3))/(g/3R) I=2mR Problem 3: a. So...

Okay thanks for the confirmation on problem 1. Problem 2: a. Would the Tension=2mg? That seems to make sense to me. I applied Newton's Second, it's at rest so T-2mg=0. b. Still working on it...another hint appreciated... Problem 3: a. Would I=(m)(L/2)2+ (m)(L/2)2+ (m)(L/2)2? One for...

3 Questions about Rotational Motion; Test Tomorrow! Please Help! Problem 1 Homework Statement A uniform disk of radius .12m and mass 5kg is pivoted so that it rotates freely about its axis. A string wrapped around the disk is pulled with a force of 20N. a. What is the torque exerted on...

Well we are currently on Bonding and Covalent Bonding in Orbitals and I took around 10 pages of notes on the bonding chapter so I feel as if I have that down pat. However, hybridization just seems over my head and I can't seem to understand what they are talking about. Some chapters just don't...

I decided to take AP Chemistry but since the AP scores for the teacher at my school are spectacularly low, I decided to take it outside of school in an independent studies program my school offers. I expected the teacher to be more competent than my school's but, 3 weeks in, I have not had a...
