Strontium-90 has a half life of 29 years, how much strontium-90 is left from the Chicago pile reactor that was active around 87

agasfer [191]

Answer:

The answer is below

Explanation:

The half life of a substance is the time required by that substance to reduce to half of its initial value. The half life is calculated using the formula:

$N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\where\ N(t)=quantity\ of\ substance \ remaining, N_o=initial\ quantity\\of\ substance, t=time\ and \ t_\frac{1}{2}=half\ life\ of\ substance$

Given that t = 87 years, half life = 29 years, therefore the quantity of strontium-90 left is:

$N(t)=N_o(\frac{1}{2} )^\frac{87}{29} \\\\N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\N(t)=N_o(\frac{1}{2} )^3\\\\N(t)=\frac{1}{8} N_o$

That is one-eight of Strontium 90 would be left after 87 years

If a frog cell with 2n = 26 undergoes mitosis one of the daughter cells would have _____ chromosomes and if that frog cell with

KengaRu [80]

Answer:

C.) 26 - 13

Explanation:

During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.

DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.
