Homework Statement Solve the energy eigenvalue problem for the finite square well without using the symmetry assumption and show that the energy eigenstates must be either even or odd. Homework Equations The finite well goes-a to a and has a potential V0 outside the box and a potential...

Thanks for the answer. Can you give me any links to or further reading on Hawking's analytical work that dealt with this? Also, what did he mean by "imaginary time". Many Thanks!

Hi- I recently read Brian Greene's Fabric of the Cosmos which led me to think of an interesting concept that I would appreciate further explanation on. On page 456 Greene describes how in the multiverse view, if you traveled back to the past, you would have gone back to a past in a parallel...

Right I figured that after your most recent explanation. I think I'm good now. Thanks so much. You were incredibly helpful.

Thanks I understand that I messed up. Did you not see my second post though? I realized I needed to decide the 5AH by the 100A which yielded 18 min.

Wait after further reflection I think I've done this backwards. I should have divided the 5AH by the 100A, giving me .05H and then multiplied this by 6 to get .3 or 18 minutes. Is this the right way?

Many thanks for this, it has made the problem much more clear. Using the formula, I obtained I=100A, which is the necessary current that the batteries must supply to the toaster. Since each battery has a capacitance of 5ah, I believe I need to divide the current by the capacitance. This would...

Would it be 30 hours? As in 900W/30AH=30H? Or am I missing it here?

I think this makes sense now. Are you referring to the fact that Resistance is equal to potential difference/current?

1. The rate of flow is the current, is it not? This is the change in charge over the change in time. 2. The D cells in a series all have the same current, but add together to give the total voltage and resistance. After looking at the units attached to the different quantities, do I need to use...

Homework Statement A toaster, which uses 6 alkaline D batteries, must produce at least 900 W of thermal energy. D cell batteries have a capacity of about 5 Ah. How long can the batteries run the toaster? Homework Equations The Attempt at a Solution Well I know that Power is (J/s)...

After working on this farther by setting the Coulombs law of the original two charges equal to that of the new charge and the larger one (assuming they both equal 0), I got that r=d*sqrt(n/q), where r is the distance the particle should be placed, d is the original distance between the two...

Graphene, thanks for the response. Setting the third charge with the larger charge yields (9kqn)/(d^2) where n is the new charge and d is the arbitrary distance. However setting this to zero yields d=0, as you would multiply by zero. My questions are 1) How do I solve this with two variables...

Homework Statement Two point charges, one with charge +q and the other with charge +9q, are placed a distance "d" apart. It is possible to place a third charge so that the net electrostatic force on all three charges is zero. What are the sign, magnitude, and position of this third charge (in...
