Suppose you find a rock that contains 10 micrograms of radioactive potassium-40, which has a half-life of 1.25 billion years. By
attashe74 [19]

Answer:

The rock is 3.75 billion years ago.

Explanation:

Given that:

Half life = 1.25 billion years

1 billion years = 10⁹ years

So,

Half life = 1.25 × 10⁹ years

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac {ln\ 2}{1.25\times 10^9}\ year^{-1}

The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹

Initial amount [A₀] = 80 micrograms

Final amount [A_t] = 10 micrograms

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

So,  

10=80\times e^{-5.5452\times 10^{-10}\times t}

80e^{-5.5452\times \:10^{-10}x}=10

\frac{80e^{-5.5452\times \:10^{-10}x}}{80}=\frac{10}{80}

\ln \left(e^{-5.5452\times \:10^{-10}x}\right)=\ln \left(\frac{1}{8}\right)

x=\frac{10^{10}\times \:3\ln \left(2\right)}{5.5452}=3.75\times 10^9

So,

<u>The rock is 3.75 billion years ago.</u>

Why does the book Justin is reading say that black people was still not free even though slavery was officially over
miskamm [114]

Answer:

Assuming that he is saying it metaphorically, it most likely means that segregation was still going on and that they still were forced too be different people.

According to your text, the greatest problem with all of the employee comparison methods is that they do not provide information
Alexeev081 [22]

I believe the answer is: how well an employee is actually doing

Unlike in education environment, workplaces do not adopt GPA system do measure how well an employee perform, since there are a lot of factors that could determine employees'performance, depending on the position that they're in. Because of this, it is hard to develop a comparison method that could objectively measure employees' worth.
