Solved: 114 In exercises that require numerical values, use Table12.7.1 and the

Chapter 12, Problem 10

(choose chapter or problem)

In exercises that require numerical values, use Table 12.7.1 and the following values, where needed:

radius of Earth = 4000 mi = 6440 km

radius of Moon = 1080 mi = 1740 km

1 year (Earth year) = 365 days

The universal gravitational constant is approximately

$G=6.67 \times 10^{-11} \mathrm{~m}^{3} / \mathrm{kg} \cdot \mathrm{s}^{2}$

and the semimajor axis of the Earth’s orbit is approximately

$a=149.6 \times 10^{6} \mathrm{~km}$

Estimate the mass of the Sun in kg.

Equation Transcription:

$G\ =\ 6.67\ \times{}1{0}^{-11}\ {m}^{3}/kg\cdot{}{s}^{2}$

$a\ =\ 149.6\ \times{}\ 1{0}^{6}\ km\$

Text Transcription:

G = 6.67 × 10^−11 m3/kg·s^2

a = 149.6 × 10^6 km
