1. ### Mechanical advantage machines

I've been at this problem for a good hour now and I just can't figure it out :bugeye: Please help me think through this! It is a very difficult problem in my opinion. Or maybe I'm just missing a fundamental point...Thanks in advance...
2. ### RC Circuits, capacitor charges and voltages

0_o I've taken both physics I and II in college and I'm brushing up for the MCAT. I most definitely never came across either theorems :X THank you for all of your insight! It help tremendously! :)
3. ### RC Circuits, capacitor charges and voltages

BvU: that was an amazing explanation! ....Why can't textbooks just put it that simply! I wish I could transplant y'all's brains into my head for this test. Yikes! :)
4. ### RC Circuits, capacitor charges and voltages

Ok I think I got...so when they're in series maximum charge q = emf x C but when you have resistors in parallel with the capacitor, it's another story?
5. ### RC Circuits, capacitor charges and voltages

Whoops sorry about that! I was trying to make it easier for you to understand haha. Ok...sooooo basically, question 24 is just an awful question? And so, when a current comes across a resistor before reaching the capacitor, that resistor will zap some of the voltage that would otherwise get...
6. ### RC Circuits, capacitor charges and voltages

7. ### RC Circuits, capacitor charges and voltages

BvU hi. that still doesn't explain problem 24 though. Problem 24 is answer C. The answer provided states "there is no dependence on resistance of any kind".
8. ### RC Circuits, capacitor charges and voltages

Ok I have edited my question, hopefully this explains it better. I am still so confused.
9. ### RC Circuits, capacitor charges and voltages

No - questions 23 and 24 are stand alone questions and neither has a figure provided. I will edit this post again with my thoughts and further clarification of why I am confused, please check again gneill in a few minutes. Thanks so much.
10. ### RC Circuits, capacitor charges and voltages

These are 2 stand alone problems, however the answers disagree with one another and I am trying to reconcile their differences. Any insight would be appreciated! :) The answer is C. The answer provided with this question is that "there is no dependence on resistance of any kind". However the...
11. ### Conducting bar on a rail question

qvB = IxB? Where x is distance?
12. ### Conducting bar on a rail question

I took physics a while back and am only just refreshing before the MCAT. I remember the equation F = Eq + qvB.
13. ### Conducting bar on a rail question

This problem is way over my head. :/ *white flag* I surrender. Hopefully it doesn't come up on the MCAT!
14. ### Conducting bar on a rail question

The passage says it definitely does climb it, but gives no explanation as to why. I think they assume I should know :/ lol
15. ### Conducting bar on a rail question

I say that because my textbook says that this is the only reason we use rotating coils in real life, because having infinitely long rails to produce current is impractical.
