A research team has discovered that a moon is circling a planet of our solar system: The moon orbits the planet once every 7 hours on a nearly circular orbit in a distance R of 48000 km from the centre of the planet. Unfortunately, the mass m of the moon is not known. Use Newton’s law of gravitation with G = 6.67 · 10−11 m3 /(kg·s 2 ) to approach the following questions: F = G · mM R2 (a) Based on the observations, determine the total mass M of the planet. (b) Which moon and planet of our solar system is the team observing? (Use literature.) Answer it fast plz |

Answer» (a) we know, R^3 = (GT^2 /4π^2 ) MOR, (48.16)^3 = { (6.67.10^-11) (7.3600)^2 / 4π^2 } M M= 1.03.10^26kg(B) It is NEPTUNE. Explanation: |
