What multiple of the energy needed to escape from Earth gives the energy needed to escape from (a) a moon of mass `1.472 xx 10^(23)` kg and radius `3.480 xx 10^6` m and (b) Jupiter?

Explanation

To solve the problem, we need to calculate the escape energy from Earth, the moon, and Jupiter, and then find the ratios of these energies.

### Step 1: Calculate the escape energy from Earth

The formula for escape energy \( E \) is given by:

\[
E = \frac{GMm}{R}
