    Escape Speed and Atmospheric Temperatures of Planets: Calculations and Analysis

    a) Show that the escape speed for a particle to leave the gravitational infuence of a planet is given by (2GM/R)^1/2, where M is the mass of the planet, R is its radius, and G is the gravitational constant. b) The temperature near the top of Jupiter's multicolored cloud layer is about 140K. The...

    Molecular Speeds in a Laboratory Apparatus

    A physics student measures molecular speeds in a laboratory apparatus and concludes that the distribution of speeds is such that: 10% have a speed of 200 m/s 10% gave a speed of 250m/s 15% have a speed of 500m/s 30% have a speed of 650m/s 20% have a speed of 900m/s 15% have a speed of 1300...
