the average distance between the earth and the sun is 1.5\times10^{8}\,\mathrm{km}1.5×10 8 km. the earth's average orbital velocity is 2.99\times10^4\,\mathrm{m/s}2.99×10 4 m/s, its radius is 6370 km, and its mass is 5.98\times10^{24}\,\mathrm{kg}5.98×10 24 kg. we can model the earth as a solid sphere, rotating about its axis with angular velocity 7.27\times10^{-5}7.27×10 −5 rad/s. calculate the angular momentum of earth in its orbit around the sun. express your answer in si units.
