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

Answer:
30888*10^8
Explanation:
concept used
law of exponent
____________________________
1.32 x 10^8 X 2.34 10^4
multiplying 1.32 and 2.34 we have
1.32*2.34 = 3.0888
10^8 X 10^4 = 10^(8+4) = 10^12
thus,
1.32 x 10^8 X 2.34 10^4 = 3.0888*10^12
3.0888 can be written as 30888/10000
1.32 x 10^8 X 2.34 10^4 = 30888/10000*10^12
10000 = 10^4
1.32 x 10^8 X 2.34 10^4 = (30888/10^4)*10^12
concept used now
1.32 x 10^8 X 2.34 10^4 = 30888*10^(12-4)
1.32 x 10^8 X 2.34 10^4 = 30888*10^8
thus, answer is 30888*10^8
Answer:
A key drawback with the use of tests to screen individuals for desirable characteristics is that It is a time-consuming procedure.
It is very important for the employees to know exactly what they must look into and assess the characteristics accurately. This process is very time consuming and takes up a lot of patience and resources to carry the tests.
