Answer» Solution :`{:("TIME period of"),("the moon T"):}}=1.769"days"` `{:("Orbital radius"),("of the Moon"):}}=4217xx10^(2)km` Time period `T^(2)=(4pi^2)/(GM_J)(R_(M)+h)^(3)` `M_(J)` = Mass of Jupiter `GM_(J)=(4pi^(2)R_(M)^(3))/(T^2)[hltltR_(E)]` `{:("MEAN radius of"),("the moon" R_(M)):}}=1.737.1xx10^(3)m` `M_(J)=(4pi^(2)R_(M)^(3))/(GT^2)` Mass Jupiter `M_(J)=(4xx(3x14)^(2)xx(1737xx10^3)^(3))/(6.67xx10^(-11)xx(1.769)^(2))` `=(20668xx10^(27))/(20872xx10^(-11))` `=0.99022xx10^(27+11)` `=990226xx10^(38-5)` `=990226xx10^(33)` `=0.990226xx10^(27)` `~=1xx10^(27)kg` |
