Explanation / Answer
1. Radius of titan = 2576 km
Titan’s radius by Earth’s Moon’s radius = 2576/1737 = 1.483017
So the nearest answer is 1.482
2. Mass of titan = 1.3452 x 1023 kg
Mass of earth =5.972 × 10^24 kg
Mass of Earth’s Moon = 0.0123 Earth masses = 0.0123 * 5.972 × 10^24 kg
Mass of Titan in multiples of Earth’s Moon mass = 1.3452 x 1023 /(0.0123 * 5.972 × 10^24)
= 1.83131
The nearest answer is 1.846Related Questions
