1. ### Chemistry Question - Benzene

Hi all! I have a question regarding benzene and the pi-MOs for benzene. Basically, when you're forming the MO model but manipulating the equations (ie: MO = sum Ci=phi-subi = 1Cs!s1 + C21S2 for H-H sigmna bond) in this equation, how many terms would go in for benzne? Would it be 6? I know...
2. ### Optics and Cameras

If it is desirable to produce the large image, then why does the camera get wider/longer? I agree, I'm not sure what the question is exactly asking! Thanks for your help thus far!
3. ### Optics and Cameras

Homework Statement Why does a camera get wider/longer? Homework Equations N/A The Attempt at a Solution Well, I assume that it is to produce the largest image that can possibly be on the film. But I'm a little confused on the question as a whole? Am I on the right track and...
4. ### RC Circuits half-life help

Thanks for your reply, berkeman. It does, indeed, help. So now that I have this, can i just plug it into this formula: where the halflife (t 1/2) = (ln2)RC and that I derived from V(1/2)/Vi = e^((-t1/2)/RC) so that the original equation is just that, t1/2 = RC ln2 and the new equation...
5. ### RC Circuits half-life help

Hey Everyone, I have a question regarding physics. Say you're given an RC circuit with two identical capictors and two identical resistors and that the two resistors are connected in parallel and the two capacitors are connected in parallel and both are used in the circuit. How can you...
