    Physics of ISM: Pressure, Volumes, Masses

    I converted my answer for pressure. I apologize, I simply forgot to do that before. I got that the pressure for each, assuming each follows the ideal gas law, would be about ## 1.38 \times 10^{-14} Pa ##, which is right around the vacuum pressure out in space. For part (b), I made the assumption...

    Radiation Pressure Force on Earth

    Homework Statement The intensity of sunlight reaching the Earth is 1360 \frac{W}{m^2}. a.) Assuming all sunlight is absorbed, what is the radiation pressure force on the earth? Give your answer in Newtons. F_r= b.) Give your answer as a fraction of the suns gravitational force on the earth...

    Perturbation Techniques and Theory for Nonlinear Systems

    That's something along the lines of what I thought of doing. I read up on the subject, and "uniform expansion" only means "without secular terms", so the approximation of my system won't blow up as t→∞. I'm just going to do the Taylor series DE thing. Thanks for your input, guys. It's greatly...

    Perturbation Techniques and Theory for Nonlinear Systems

    Homework Statement Given the equation \ddot{\theta}=\Omega^2\sin{\theta}\cos{\theta}-\frac{g}{R}\sin{\theta} Determine a first-order uniform expansion for small but finite theta. Homework Equations Other than the equation above, none so far as I am aware. The Attempt at a...
