i need help on this.(adsbygoogle = window.adsbygoogle || []).push({});

how much greater is the angular momentum of the earth orbiting about the sun than the moon orbiting about the earth? (using a ratio of angular momenta)

angular momentum = rotational inertia x rotational velocity

radius of earth (equatorial) 6.37x10^6

radius of earths orbit 1.5x10^11

radius of moon (average) 1.74x10^6

radius of moon orbit 3.84x10^8

mass of earth 5.98x10^24

mass of moon 7.36x10^22

thanks
