Answer;

D. Produces no wastes

Explanation;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. Additionally, nuclear fusion reactions yields lots energy. The energy produced is usually more than the energy consumed by the reaction. 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. Energy from nuclear fusion reactions is not coupled by production of wastes.

Answer from: Rflaig1129841

Produces no wastes

Explanation:

The reaction in which two or more than two nuclei combine to form larger nuclei along with subatomic particles is called nuclear fusion reaction. For example, when tritium and deuterium combines, then nuclear fusion occurs and hence helium forms.

Nuclear fusion process produces minimal waste or we can say that the produced waste is not so reactive. This process creates a huge amount of energy.

Hence, the correct option is (D) " Produces no wastes ".

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

$p(t)=0.3t^2+6t+80$

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

$p(0)=0+0+80=80$

according to question, we have said that if the population has twice its initial population, then it becomes

$p(t)=2\times 80=160$

so, time taken to reach this above mentioned population is given by

$160=0.3t^2+6t+80\\\\160-80=0.3t^2+6t\\\\80=0.3t^2+6t\\\\0.3t^2+6t-80=0\\\\\text{using quadratic formula ,we get }\\\\t_{1,\: 2}=\frac{-60\pm \sqrt{60^2-4\cdot \: 3\cdot \: 800}}{2\cdot \: 3}\\\\t=-29.14\ and\ t=9.149$

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
