Answer:
is uniquely defined.
Explanation:
The gravitational potential energy gained by an object being lifted is equal to the work done on the object by an applied force, which exactly cancels gravity. The applied force does positive work. When the object is being lifted, the gravitational force does negative work.
So to solve this problem, we must convert units and then cancel units simultaneously:
Therefore we know that the distance that light travels in one year is 
inches.
Answer:
pretty sure A is correct, as they are pushing in opposite directions, hence canceling each other
