    Ideal Gas Law (Simple )

    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...

    Line Integral - Work Done

    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...

    Nuclear fusion problem (2nd semester physics)

    Homework Statement The first step in nuclear fusion on the sun involves the collison of two protons, which form a deutron. Consider two protons far apart on a collison course with equal but opposite velocity. Their average kinetic energy is given by K = 1/2mv^2 = 3/2KbT where Kb is...

    Electric Potential on the z-axis

    Homework Statement Use direct integration over the charge on a wire segment to find the potential V(z) on the z-axis due to a finite segment of wire with linear charge density lambda extending along the x-axis from x = - a/2 to +a/2 Homework Equations The electric potential dV at some...

    Simple Charges/Induction Question

    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...

    Gauss' Law Problem?

    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...
