EXPLANATION
According to Newton's second law,
, where
is the mass measured in kilograms.
and
is the acceleration in metres per second square.
We substitute these values to obtain,
.
We rearrange to get,
.
We multiply out the first two numbers and leave our answer in standard form to get,
.
The correct answer is C

<h3><u>Explanation;</u></h3>
- <em><u>Nuclear fusion are nuclear reactions in which two or more atomic nuclei fuse or join to generate different atomic nuclei together with subatomic particles, such as protons or neutrons. </u></em>
- Additionally,<em><u> nuclear fusion reactions yields lots energy.</u></em> The energy produced is usually more than the energy consumed by the reaction.
- <em><u>Fusion power is a form of power generation in which energy generated using fusion reactions is used to produce heat that is used in generation of electricity.</u></em> Energy from nuclear fusion reactions is not coupled by production of wastes.
