    Show the permissible values of l and m

    n is the primary quantum number, l is the secondary quantum nuber and m is the magnetic quantum number. if n=1 then you have 1 sublevel you use the equation n^2 to find out how many orbitals it has. For example, if n=2 then sub it into the equation n^2 so (2)^2 = 4, therefore it has 4...

    Show the permissible values of l and m

    Homework Statement Show the permissible values of l and m for; a) n=1 b) n=2 c) n=3 Homework Equations I'm not really sure what they mean by permissible values, I would greatly appreciate it if someone could explain this to me and help me get started. thank you The Attempt at a...

    Escape Velocity (from surface of the Earth)

    Homework Statement A satellite with a mass of 5.00x10^2 kg is in a circular orbit, whose radius is 2re, around Earth. Then it is moved to a circular orbit with a radius of 3re. e) Calculate the escape velocity for the satellite if it is on Earths surface. Homework Equations Vesc =...

    Gravitational potential energy problem.

    also d) for the same problem asks me to Calculate the speed it would need in order to maintain its new orbit. I did v = sq.root of Gme/r so I got v = sq.root of (6.67x10^-11)(500)/3(6.38x10^6) v = sq.root of 1.742424242x10^-15 v = 0.000000042 m/s that seems way to small to me, can...

    Kepler's constant and average radius of orbit

    Homework Statement Given that Jupiter has a mass of 1.9x10^27 kg, and the sun has a mass of 1.99x10^30 kg: a) Calculate the value of Kepler's constant for Jupiter. b) If Jupiter's orbital period is 11.89 Earth years, calculate the average radius of its orbit. Homework Equations K...

    Gravitational potential energy problem.

    So I got the answer for both 2re and 3re which are Ep = -1.56*10^10 Ep = -1.041969697*10^10 and then for the next question it asks to determine the change in gravitational potential energy which I'm pretty sure is (Delta)Ep=Ep2-Ep1 which I got 5180303030 J ( I just subtracted the two...

    Gravitational potential energy problem.

    Homework Statement A satellite with a mass of 5.00 x 10^2 kg is in a circular orbit, whose radius is 2re, around Earth. Then it is moved to a circular orbit with a radius of 3re. a) Determine the satellite's gravitational potential energy in each orbit. Homework Equations Ep= -GMm/r...
