Answer:
c. Moon A is four times as massive as moon B
Explanation:
Let's assume the:
- mass of the object =
- mass of the moon A =
- mass of the moon B =
- distance between the center of masses of the object and moon B =
According to the given condition the object is twice as far from moon A as it is from moon B
- ∴distance between the center of masses of the object and moon B =

Answer:
E = 2.7 x 10¹⁶ J
Explanation:
The release of energy associated with the mass can be calculated by Einstein's mass-energy relation, as follows:
where,
E = Energy Released = ?
m = mass of material reduced = 0.3 kg
c = speed of light = 3 x 10⁸ m/s
Therefore,
<u>E = 2.7 x 10¹⁶ J</u>
