Consider the incomplete equation below

Superscript 4 subscript 2 upper H e plus superscript 4 subscript 2 upper H e right arrow question mark.

If this equation was completed, which statement would it best support?
Nuclear fusion produces elements that are heavier than helium.
Nuclear fusion produces elements that are lighter than helium.
Nuclear fission produces elements that are heavier than helium.
Nuclear fission produces elements that are lighter than helium.

Nuclear fusion produces elements that are heavier than helium.

Explanation:

Nuclear fusion is a nuclear reaction in which two lighter nuclei combine to give a heavier nuclei releasing tremendous amount of energy in the process.

When two nuclei fuse, a heavier nucleus is formed. This is a kind of nucleosynthesis, the synthesis of new nuclei.

Hence fusion of two helium nuclei will produce elements heavier than helium. Hence the answer.

the answer is a 3.8cm

explanation:

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

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

so, our quadratic equation becomes,

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

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

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.
