Final answer:
The work done by gravity during the collapse of a star cannot be determined without additional information.
Step-by-step explanation:
The work done by gravity during the collapse of a star can be calculated using the formula:
Work = force × distance
The force of gravity can be calculated using Newton's Law of Universal Gravitation:
F = G × (m1 × m2) / r^2
where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between the objects.
In this case, we are given the mass of the star (2.0 x 10^30 kg) and the energy produced during the explosion (1.00 × 10^44 J). However, we do not have the distance values required to calculate the work done by gravity. Therefore, without additional information, it is not possible to determine the work done by gravity during the collapse.
