also include the units please. im not sure if i have the right answer because the site tells me my units are wrong, so for all i know i have the right answer but i cant tell

(a) L1 = M•v•R =
Earth’s mass is M = 5.97•10^24 kg,
R= 1.5•10^11 m (Earth-Sun)
v=ω•R=2•π•n•R
n=1 rev/year =1/365•24•3600 rev/s
L1 = M•v•R = M•2πn•R²= …(kg•m²/s)
(b)
Earth’s radius is r = 6.378•10^6 m.
n= 1rev/day =1/24•3600 rev/s
L2 = I•ω1= (2•M•r²/5) •2•π•n•r= …(kg•m²/s)
