The researcher best use the qualitative research method of using a case study of a group of monkeys in their wild habitat and observe them, making notes on observations and developing trends in their behaviour to determine research clues as to the activity of the monkeys and how they act in their habitat with one another and in response to the environment itself.
Yes. A representative must at least be 25 years old, live in the state in which they are elected, and have been a US citizen for at least 7 years
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
