Homework Statement
I am wondering how for determine the central atom's orbitals from the point group character tables described by group theory.
For example CO3^-2 (D3h)
Carbon's (central atom) p-orbitals are described by a1''+e'. The s-orbital is a1'

Homework Statement
How do you find the contributions per atom for calculating the reducible parts?
For example CO3-2 has pt. grp: D3h.
From the character tables-- the first row (unshifted atoms) is: 3,0,1,3,0,1. Second row (coefficients): 1,2,3,1,2,3 Third Row (contributions per atom)...
***"Oh, right.
I'm confused. Is the above equation 2volts = (q/c) - I3R3 not correct. I don't see how you couldn't just find q from this.
It is, but you have two unknown values there. You have to find I3 first."***
Right, I did that and I solved for q. This does not come out to the answer...
I just found an answer (without solution) and it said it is supposed to be 7.2nC. Using the first idea I had, I pretty much got the answer with t1=11.5microseconds :
**"RC was correctly found to be 40microSeconds.So then the goal is to find the time at t1. The 2volts across A and B must be...
"The voltage drop at your RC part is not constant."
yeah but isn't \tau (time-constant) always constant from the time the switch is closed to a "long time after"?"Step by step. You can calculate the voltage drop at the right transistor. Based on this, you can calculate the current there, and so...
1) I mean RC as in the time constant= total resistance*capacitance = 5/3R*C
"You can use the usual circuit rules to get the charge..."
How do you do this?
2volts = (q/c) - I3R3 and solve for q?
Homework Statement
Switch is initially opened with the capacitor uncharged. At t=0 the switch is clsoed. At time=t1 later, the potential difference between A and B is 2.00volts
Find the charge on the capacitor at time t1.
R=10,000ohms
C=2.4nF
Vb=12volts
VA->B-=2.00volts

I completely agree that using class time for problem solving and homework is a waste of time.
I don't agree that students don't have access to solutions to completed homework/exams/quizzes. Sure talking to professors and other students is super important in training for the world of science...
Any advice on a chem major/math minor going into materials science grad degree?
Most helpful curriculums?
How deep should you take physics/math in undergrad?
Job Outlooks/what kind of work expected?
Is it really a safe jump for a chem major?
Will it be easy to push away from chem and more...
Wohoo! 3hrs later! Now I can continue on and do a MILLION other physics problems! YES!
Grand finale of solutions:
C1 is in parallel with C23:
1) 480pC/(C1+C23)=480pC/(60pF)=8V across C1, C23
2) V3=Q23/C3=8/3V
So how do you find the voltage on c1 if you don't have a way to relate it to the other capacitors? I'm really trying here but it isn't clicking.
I'm having a tough time taking this concept and applying the equations for capacitors to this problem...
Also, if the other capacitors only take some...
So initially the capacitor becomes charged with 12 volts across it. The current stops. Then the switch is in place and the charges redistribute. With the battery disconnected,the capacitor has 12 volts that gets redistributed through the 3 capacitors. Initially C1 has 12v(40pF)=480pC of charge...
