Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.
<h3>What is Supernova?</h3>
This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.
The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.
This is therefore the reason why it was chosen as the most appropriate choice.

We feel comfortable under a fan when we are perspiring because the fan actually increases the rate of evaporation of sweat. This means that the perspiration (or sweat) evaporates more quickly when we are under a fan, which also means that our body feels cooled and comfortable because of the lack of sweat.
The stored energy of an object is kinetic energy
