Answer:

Sir Humphry Davy, an English chemist, invented the first electric light in 1809. Davy connected two wires to a battery and attached a charcoal strip between the other ends of the wires. The charged carbon glowed, making the first arc lamp. Much later, in 1878, Sir Joseph Wilson Swan, an English physicist, was the first person to invent a practical electric light bulb (it glowed for 13.5 hours). This innovator built on the work of the many, many scientists before him who had improved on the original electric light. He found that a carbon paper filament worked well, but burned up quickly. Thomas Edison placed his carbon filament in an oxygen-free bulb. (Edison based his designs for the light bulb on the 1875 patent he purchased from innovators Henry Woodward and Matthew Evans.) Edison’s 1879 bulb could be used for 40 hours without burning out; by 1880, his bulbs could be used for 1,200 hours.

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.

Why is light so important in transporting information?
Alex Ar [27]
Perhaps the most successful way we've been able to use light to transfer information is fiber optics. ... Through rapid changes in the light, you can send highly complex signals down the cable. These are most often used either for high speed internet connections, or for sending sound signals to home theater systems.

I. Introduction
a. You all must know that alcohol abuse can cause serious damage to the human body. But did you know that millions of people in America are oblivious of the effects it has on you? I am going to persuade you to drink alcohol carefully and responsibly. I chose this topic because I myself have been affected by this issue and would like to persuade you on how harmful alcohol abuse really is. I am also going to talk to you about the types of drinking, how it can be avoided, and how much it can change your life. 
II. Body 
A. What alcohol abuse is
1. There are two types of drinking; heavy drinking and binge drinking
2. According to the Centers for Disease Control and Prevention, “Binge drinking, the most common form of excessive drinking is defined as consuming, for women, 4 or more drinks during a single occasion. For men, 5 or more drinks during a single occasion. Heavy drinking is defined as consuming for women, 8 or more drinks per week. For men, 15 or more drinks per week.” End quote.

B. Drinking can cause a lot of negative health effects physically and mentally
1. Such as, yellowing of the eyes, liver damage, violent behavior, hospitalization, loss of appetite, poisoning, etc. 
C. People should be more careful with how they drink
1. DUI and accidents: 
2. Families can be broken: Many families who have someone who drinks excessively, have been abused due to the damage alcohol has in them. 
3. You can lose a lot of money because of buying bottles of alcohol all the time. All the money wasted on alcohol could have been used for taxes, bills, and other needs. 
D. What people should do to avoid alcohol abuse 
1. Abstinence: not drinking at all can help avoid alcohol abuse by a lot. Many people would be safe 
2. Moderate/responsible consumption (health benefits of one glass of red wine) If drunken responsibly, it can benefit you in some ways. According to the Canadian Nursing Home of Health Media states, drinking red wine can enhance your memory, 

This means a lot to me because my two grandfathers lost their lives as a result of complications from alcohol abuse

The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many wou
katovenus [111]

Answer:

50 atoms of carbon-14

Explanation:

From the question given above, the following data were obtained:

Original amount (N₀) = 100 atoms

Half-life (t½) = 5700 years

Time (t) = 5700 years

Amount that decay =?

Next, we shall determine the number of half-lives that has elapse. This can be obtained illustrated below:

Half-life (t½) = 5700 years

Time (t) = 5700 years

Number of half-lives (n) =?

n = t / t½

n = 5700 / 5700

n = 1

Next, we shall determine the amount remaining. This can be obtained as follow:

Original amount (N₀) = 100 atoms

Number of half-lives (n) = 1

Amount remaining (N) =?

N = 1/2ⁿ × N₀

N = 1/2¹ × 100

N = 1/2 × 100

N = 50 atoms

Finally, we shall determine the amount that decayed as follow:

Original amount (N₀) = 100 atoms

Amount remaining (N) = 50 atoms

Amount that decay =?

Amount that decay = N₀ – N

Amount that decay = 100 – 50

Amount that decay = 50 atoms

Therefore, 50 atoms of carbon-14 have decayed during the time.

The document that's selected based on the information illustrated is The Rule and Grandeur of Moctezuma.

<h3>How to illustrate the information?</h3>

It should be noted that Montezuma was one of the last Aztec emperors and uder his rule, the Aztec empire were at their best conquering other tribes as well as expanding their territories.

During the reign, the Aztec Empire reached its greatest size and through warfare, Moctezuma was able to expand the territory as far as south of the Xoconosco in Chiapas and Isthmus of Tehuantepec. He also incorporated the people of Zapotec and Yopi into the empire. However, he allowed the Spanish to conquer them due to his religious superstition.

Hernán Cortés was one of the many Spanish explorers who would follow in Columbus's wake and he lived in the West Indies for over a decade before violating orders and invading what would become Mexico.

Furthermore, Moctezuma died in the evening hours in 1520, in his palace in the Aztec capital, while a prisoner of the Spanish conquistadors.
