The net force will point towards the acceleration of the object, as supported by Newton's second law.
Answer:
I think the answer is B. amount of energy present but I'm not 100% sure
Explanation:
First,
where 
is density, 
is mass, and 
is volume. We can compute the volume of the roll:
When the roll is unfurled, the aluminum will be a rectangular box (a very thin one), so its volume will be the product of the given area and its thickness 
. Note that we're assuming the given area is not the actual total surface area of the aluminum box, but just the area of the largest face (i.e. the area of one side of the unrolled sheet of aluminum).
So we have
where 
is the given area, so
If we're taking significant digits into account, the volume we found would have been 
, in turn making the thickness 
.
The government should put it support in a combination of sources, as no
source in the present can fully provide all energy requirements.
