Question
12. The mass of Earth is 5.976 x 106 kg. The mass of the moon is 7.35 x 10 kg. Earth's mass is how much larger than the Moon's? (To calculate a problem like this how much larger -divide the larger number by the smaller number. The units will cancel out and your answer will have no units. Your answer then is expressed as Earth's mass is times larger than the Moon's.") 13·The mass of Mars ("the Red Planet") is 6.424 x 1023 kg. How much larger is the Earth's? 14. How does the Earth's mass compare to the followin A) Jupiter ("the Giant") with a mass of 1.899 x 10 kg. Do not share your copy of this lab with anyone.

12. The Earth's mass is 8130.6 times larger than that of the moon.
Calculations: (5.976*10^26) / (7.35*10^22) = 8130.6
13. (5.976*10^26) / (6.424*10^23) = 930.26 * 10^48
So, the Earth's mass is 930.26 * 10^48 times the mass of Mars.
14. A.(1.89*10^27) / (5.976*10^26) =3.162
B. (5.976*10^26) / (1.2*10^22) =498000
C. (1.989*10^30) / (5.976 * 10^26) = 3227.9
D. (5.976 * 10^26) / (3.31*10^3) = 1.8*10^23
15. 93*10^6 miles= 4.2*10^11 Km.
Time= Distance/Speed= 4.2*10^11 Km/ 300000 Km per second = 1404189 seconds = 3900 hours.
So, it takes 3900 hours for sunlight to reach he earth.
16. 93 million miles= 149668992 Km. This is the distance between Earth and sun.
Distance between Neptune and sun = 45*10^8 Km.
Distance between Neptune and Earth = (45*10^8) Km - (149668992) Km = 4350331008 Km (Answer)
Light travels at 300000 Km/s
Time taken by light from Neptune to reach the Earth = Distance/Speed = 4350331008/300000 = 14501.1 seconds= 4.02 hours. (Answer)
