<span>There are several principles of democracy. In a democratic society, everyone is
equal. This means that they have the
same rights no matter who they are. The
laws and institutions are based on fairness and impartiality. This means no one
gets preferential treatment. Ideas come from individuals and those ideas are shown
to a council who vote on it. People have
the right to express their ideas in a democratic society. Though the majority holds power, the minority
and absentee members’ rights will be respected.
Whether you are from the majority or minority, you have rights and those
rights allow you to take part in important discussions or events. Systems and procedures in a democratic
society is done in openness where everyone has the right to know the whole
truth. Leaders and officials are chosen
by the people through an election process.
When their term of office ends, they return to civilian life. Power in all
branches of government is shared equally.</span>
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}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%20%7Bln%5C%202%7D%7Bk%7D)
Where, k is rate constant
So,
![k=\frac {ln\ 2}{t_{1/2}}](https://tex.z-dn.net/?f=k%3D%5Cfrac%20%7Bln%5C%202%7D%7Bt_%7B1%2F2%7D%7D)
![k=\frac {ln\ 2}{1.25\times 10^9}\ year^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%20%7Bln%5C%202%7D%7B1.25%5Ctimes%2010%5E9%7D%5C%20year%5E%7B-1%7D)
The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,
![10=80\times e^{-5.5452\times 10^{-10}\times t}](https://tex.z-dn.net/?f=10%3D80%5Ctimes%20e%5E%7B-5.5452%5Ctimes%2010%5E%7B-10%7D%5Ctimes%20t%7D)
![80e^{-5.5452\times \:10^{-10}x}=10](https://tex.z-dn.net/?f=80e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%3D10)
![\frac{80e^{-5.5452\times \:10^{-10}x}}{80}=\frac{10}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B80e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%7D%7B80%7D%3D%5Cfrac%7B10%7D%7B80%7D)
![\ln \left(e^{-5.5452\times \:10^{-10}x}\right)=\ln \left(\frac{1}{8}\right)](https://tex.z-dn.net/?f=%5Cln%20%5Cleft%28e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%5Cright%29%3D%5Cln%20%5Cleft%28%5Cfrac%7B1%7D%7B8%7D%5Cright%29)
![x=\frac{10^{10}\times \:3\ln \left(2\right)}{5.5452}=3.75\times 10^9](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%5E%7B10%7D%5Ctimes%20%5C%3A3%5Cln%20%5Cleft%282%5Cright%29%7D%7B5.5452%7D%3D3.75%5Ctimes%2010%5E9)
So,
<u>The rock is 3.75 billion years ago.</u>
Answer:
Political support began with Alexander Hamilton and his Report on Manufactures at the turn of the 19th century, and continued with the Whig Party, led by Henry Clay from 1832 until its demise in 1852, and then by the Republican Party from its formation in 1856.
Answer:
Sure
Explanation:
this is because;
1. In rural areas most foreign technologies are unavailable so they tend to survive from tradition.
2. Most electronic gadgets won't be effective in rural area due to lack of sources like electricity
The correct answer to this open question is the following.
By 1776, the majority of American colonist truly supported independence from Great Britain. Indeed, the Declaration of Independence was issued on July 4, 1776, during the Revolutionary War.
People form the colonies were angry with the English monarchy due to the heavy taxation without voice and representation in the British Parliament. Taxes such as the Stamp Act, the Sugar Act or the Tea Act were big causes that started the Revolutionary War.
