Wow, never knew about this until the mass email about the login issues. ...and I just bought ~$200 of books from amazon 2 weeks back. Dang.

Perhaps nice compact solutions simply don't exist if your expressions are too complicated. Do you really require an algebraic expression? If not, plug in your expressions for w and v, then use Solve/NSolve.

Well...*technically* N(t1) = N_0 * e^{-\lambda*t1} , so you shouldn't have canceled out the N0, although it does not affect your final answer.

We use the terms cis-but-2-ene (best be clear where the double bond is) and trans-but-2-ene in my chem classes, so I think they're fine.

In no way does the classical theory imply that the statement is false. As said above, quantum and classical theory do not disagree on the definition of the word "intensity".

Hm, maybe the discharging effect of you touching it is not that significant after all...>.<

You have to charge both combs separately, then bring them together to see if they attract or repel.

Both the object and the comb will be charged. What you really want is the comb to be charged, not the objects!

They're really pretty much the same thing isn't it? If L is unknown you will have to give your answer in terms of L anyway.

That's because you shouldn't be touching the charged comb. If you do, you'll act as an Earth and the comb will be discharged. As for the other materials, it's for you to try and find out =D

1) Can you find the displacement (with respect to the flagpole) of each runner at any given time? When they meet, what must their displacement be? 2) How long does it take for the train to stop with the given acceleration? Thus how far would it have travelled?

The purpose of the second comb is to find out the polarity of the charges! You have no way of knowing if you're using just a single comb. You shouldn't expect to find them charged in their natural state.

Yes, it should be wanting 2.90.

What are the coordinates of q1 and q2? Therefore what is the coordinate of the point with zero E field?

You ought to count from the origin...
