Uranus orbits the Sun with an orbital radius of 2.56 x 107 m. Given that the mass of the Sun 1.99 x 1030 kg, calculate the period of Uranus’s orbit in seconds.
Should I use this formula T = 2 pi x square root of r^3/Gm ? (not the one topsquark gave bcuz there's no mass given for Uranus?
Venus orbits the Sun with an orbital radius of 6.05 x 106 m. Given that the mass of the Sun is 1.99 x 1030 kg, calculate the orbital velocity of Venus
Should I use V = square root of Gm/r ? |
