An unknown planet has been discovered halfway between Jupiter and Mars. Estimate the length of this planet's year in # of days.
1 year on Neptune = 60,190 days
1 year on Uranus = 30,687 days
1 year on Saturn = 10,759 days
1 year on Jupiter = 4,333 days
1 year on Mars = 687 days
1 year on Earth = 365 days
1 year on Venus = 225
1 year on Mercury = 88 days
2510 days (average of mars and jupiter)
(687+4333)/2
What is the distance between two objects (m1 = 6*10^15 kg)(m2 = 8*10^24 kg) if the force of gravity between them is 11.4*10^6 N?
About 5.3*10^11 meters
