<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

<span>Federalism means the way of government where there are
various levels of government. As different level government system is more
accessible for general people where they can say what they want or express
their opinions about something being right or wrong. So in my opinion for the most
part Federalism is a tool for the protection against "majority
tyranny" and therefore a protection for the minority.</span>
<span>To
explain this in an example, if a state banns all the women to be employed at
any level, the federal government will intervene and stop this unjust decision,
or vice versa. </span>
The correct answer is C) reduce the economic hegemony of the global north.
The emergence of the BRICS (Brazil, Russia, India, China, South Africa) countries has the potential to most likely reduce the economic hegemony of the global north.
For many years the northern hemisphere nations such as Western Europe, the United States, and Canada have dominated trade and the economic world in general.
However, experts have considered that the advent of the BRICS (Brazil, Russia, India, China, South Africa) can represent an important block to seriously compete with those northern hemisphere powers due to the size of their markets and cheap labor.
Although those BRICS countries have interesting numbers in Macroeconomy, they still have very poor people that in Microeconomics that contrasts the Macroeconomy scenario.
