O_o. I know this is a really stupid question, but how the heck did the Q - W get to the other side of the equation? Shouldn't it be W - Q? I'm going to feel really stupid when I hear the answer, I'm sure, and I'm already done with the class so it's ultimately irrelevant, but I'd love to know.
Yeah, I hate them too. It's convenient when I want to miss class and still do the homework, I guess, and at least this one doesn't penalize for multiple tries, but I usually spend more time figuring out the right syntax than I do solving the problem.
The input calls for the integrating factor -...
Okay, I'm going insane. I have these problems completely worked out and have stared at them for centuries but the online homework is still telling me they're wrong. Could anyone here take a look and let me know? I'd appreciate it a ton.

Homework Statement
A force acts on a rectangular loop of wire, pulling it out of a magnetic field. Calculate the force required to pull the loop to the right at a constant speed of 4.42 m/s.
B = 0.44 T
l = 0.350 m
v = 4.42 m/s
R = 0.356 ohms

Do I? I really don't mean to come across as someone with an attitude, but the problems I'm having are real ones and not somehow a fabrication of my enormous ego, and I think everyone has had a moment in their life when they wanted to just vent and let everything out. Nothing wrong with that, nor...
I'm going to Texas Tech University (if anyone else is thinking about it, do not go to this school) I'm currently enrolled in Physics II and Calculus III. I'm making A's (well, at least close to that) in both. Here's my problem:
The amount of actual 'calculus' that we use in the course is...
