Sure I've never done that, but I will in the future. I don't see how 12 hours is relevant to exams. Yes homework could take that long to solve if you've never done homework like that before, but what does that have to do with exams?
I guess what I am saying doesn't apply to upper division...
So do you believe a grade is based on how hard a student works and not on how well they learned the material?
I also would agree with you if a class was the same difficulty for all students in a class, but in real life, for some it's easy while for others it's difficult.
Yes. If the final exam isn't cumulative then all the exams should be equal percentages. If the final exam is cumulative then I think it should count as a lot more than the other exams. That's just me though.
I agree, but I believe that homework should be optional and professor should still...
Not projects, but just regular homework. It always baffled me. If the homework counts as 10% of the grade, then a student could get 100% on all the exams and get a B, and a student could get B's on exams and get an A.
Right now I'm a sophomore majoring in physics and I honestly don't have very many skills. I am great with computer/electronics repair and networking(as a hobby), but that's about it. I kind of wish I learned some of these skills earlier, so that they would be even better by now. Which is what I...
Hey I'm in the exactly the same situation that you are(I'm taking the same classes). Honestly the math part of physics 2 is easy. The hard part is setting up the problem. I know it's very tempting to look at the solutions when solving problems, try to avoid that as much as possible. Do the...
Yea I was exaggerating about the PhD, but I know that the difficulty level of getting a PhD and a master's is much different. It makes sense that there are easier methods to solve these problems when you get to higher levels.
I'm pretty sure my professor is ok with me posting his homework up...
I was just wondering if in order to understand the higher levels of physics a very strong understanding of these is required. For example, you can't do basic single variable Calculus until you have a strong understanding of basic algebra and trigonometry. Is it the same for physics?
I want to...
No no, that's the problem itself. He wanted us to prove it (he provides us with the answer he wants us to come up with).
Yes it's something like that, but it's different for square plate capacitors. The problem is trickier than it looks.
I'm a second year college student right now and I have decided to major in physics, it is the only subject I have taken so far that has provided me with a challenge (this semester).
I am currently taking Physics 2 right now and I have got to say this class is really challenging, well not the...
When capacitors are in series, there is an induced charged (polarization) in between the two capacitors. When capacitors are in parallel the charge is evenly distributed among the capacitors (no induced charge). For example, you can look at a dielectric in between a capacitor that is smaller...
So i finally solved it, this is how I am feeling right now.

This problem took me so long to figure out, I'm glad the torture is finally over.It says:
We know that the area is constant for the dielectric(for the square side...
The volume of \frac{L^{3}}{2} is the total volume of the dielectric, but you can change the dimensions of the dielectric as long as long as l=w. For example, you can say that the dielectric is now \frac{L}{8}, 2L and 2L because the volume is still the same. You have to account for all the...
Let me know if my mathematics is incorrect, but
\frac{dq^{2}}{d^{2}t}=e^{-t\alpha}-\alpha te^{-t\alpha}=e^{-t\alpha}(1-\alpha t)=0
e^{-t\alpha}\neq0, therefore 1-\alpha t=0
and t=\frac{1}{\alpha}
You can go from there
edit: this is going from your 1st derivative, I haven't checked it myself
