Thanks for the help, everyone! It was a total brain freeze on my part...

Thanks, everyone. If I am looking at this all correctly, since I have 1 kg of diatomic oxygen, my number of moles should be: 1000 g / 32.00 g, which gives me my number of moles (n) equal to 31.25. Am I on the right track now?

Homework Statement I need to find the volume for 1 kg of diatomic oxygen for a pressure of 150,000 Pa and a temperature of 100K. This is really part of a larger project, and I need to make sure I'm not tripping up on little details. It's that 1 kg of diatomic oxygen that I am a bit unsure...

Thank you very much for the help! That really helps me out, and I appreciate it. Here's what I've done... For the lower limit, I noticed that z = sint = -1 is satisfied by 3 pie / 2. It follows then that this also satisfies y = 3cost = 0 and x = 6cost + 6sint = -6. Thus I believe my lower...

Homework Statement A curve is formed by the intersection of y^2/9 + z^2/4 = 1 and the plane x-2y-3z = 0. The particle moving along the curve goes from (6,0,2) to (-6,0,-2). Find the work done on it by the vector field F(x,y,z) = -yi + xj + yzk. Homework Equations I'm going to need to...

Homework Statement How can you use a charged rubber rod to induce a net negative charge on a metal sphere? Homework Equations None. The Attempt at a Solution OK, I understand the basics, but it seems like this question should be worded so as to inducing a net "positive" charge on...

Thanks Berkeman. Yes, I believe I would need to do that, somehow...if I can determine how to set that up into the integral. But...I have to wonder, since the problem specifically mentions that there is no charge, does that mean that there is no electric flux, either? Would it actually be...

Hello, everyone. I hope that you can help me get started on one of the problems I have due this week. Homework Statement Find the electric flux through the hemisphere z = (square root of a^2 - x^2 - y^2). - The Attempt at a Solution I'm fairly certain I need Gauss' law to help...
