Ethics is something people learn every time and it differs differently on each person based on how they where raised. The focus on "administering justice" has a guide on how to properly do so. Officers and other judicial officials do not go into the job doing what they think is correct, they do what the books, laws, and policies say.
The correct answer would be A. Negative eugenics is believing that people with "undesirable" traits shouldn't produce offspring
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years
