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

C - Excitement
This is because if you expect to succeed, you're expecting something fun and the adrenaline is pumping because you're excited to win and show those around you what you're made of.
A is incorrect as if you're expecting to succeed, you're confident in yourself and you're abilities.
B is incorrect as happiness is more of an after feeling that you get, while excitement is more of an in the moment feeling.
D is incorrect as this is similar to uncertainty; if you're not confident and you expect failure, you'd be hesitant on doing the activity.
Hope this helps!
Answer: See explanation
Explanation:
The Heckscher-Ohlin model refers to an economic theory which states that countries will export the goods that they can produce efficiently and in large quantities while they'll import those that they are less efficient in producing.
According to the H-O theorem, the pattern of trade that exists between countries as a result of the characteristics that are possessed by the countries. In such case, a capital-abundant country can produce a capital intensive good efficiently and therefore should export the capital intensive good. Likewise, a labor-abundant country can produce labor intensive good efficiently and therefore should export the labor-intensive good.
It is crucial that healthcare institutions foster a workplace that is culturally competent. It implies that the traditions and beliefs of the patient should be respected. Fadi's rights are being violated because he had the ability to select his own food.

Healthcare workers should appreciate and honour his freedom to choose his meal or dinner.
Thus, It is crucial that healthcare institutions foster a workplace that is culturally competent.
