Answer:
Explanation:
Energy and mass are related by the famous equation developed by Albert Einstein:
where m = mass and c = speed of light
This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.
Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:
E =
We use conservation of energy. Note that at the beginning of the drop, the pig has only potential energy, and at the bottom, it has only kinetic energy. Then:
Now, we multiply by
to get:
Then, we have that:
Now, we substitute.
while
. Therefore,
