Question

The mass of Pluto is approximately 1•10^22kg, while the mass of Neptune is approximately 1•10^26kg. Which of the following is true?
A. The mass of Neptune is approximately ten thousand times that of Pluto.

B. The mass of Pluto is approximately one thousand times of Neptune.

C. The mass of Neptune is approximately one thousand times that of Pluto

D. The mass of Pluto is approximately ten thousand times that of Neptune.

Answer 1

N/P=10^26/(10^22)

N/P=10^4

N/P=10000

The mass of Neptune is approximately 10,000 times greater than that of Pluto.
