Question #1e496

Answer 1

If we allow ourselves a small amount of rounding, Planet A has about 560 thousand times greater mass than Planet B.

Explanation:

`m_a/m_b = (5*10^29)/(9*10^23) = (5*10^26)/(9) = 555,555. dot 5 approx 560,000`

If we allow ourselves a bit of rounding, Planet A has about 560 thousand times greater mass than Planet B.
