At room temperature, good conductors of heat usually feel cool to the touch. This is because they conduct heat so quickly that when a finger touches them, the heat from the person's finger is immediately conducted away.

From this information, which of these materials is probably the best conductor of heat?
A.
plastic
B.
cotton
C.
copper
D.
wood

Answers

Answer 1

Answer:

The answer is C

Explanation:

This is because if you heat one end of a piece of copper, the other end will quickly reach the same temperature.  Most metals are pretty good conductors however, apart from silver, copper is the best.

Answer 2

Among these materials, copper is most likely the finest heat conductor. Hence, the right answer is (C).

What do you know about good conductor of heat?

The highest thermal conductivity metals are copper and aluminum, whereas the lowest are steel and bronze. Copper works well for heat exchangers because it is a strong heat conductor.

For instance, good electrical and heat conductors include metals like gold, silver, and iron. A free electron that is in the hot end of a metal collides with another free electron during heating to gain kinetic energy. High kinetic energy is used to propel this electron to the colder end of the metal, where it collides with a cold ion.

The chilly ion warms up in this manner. In order to heat up the cold end, this hot ion vibrates again. The hot object transfers energy in this manner to the

My name is Mark Thorson. My father was a miner, and his father before him and i work in the anthracite coal mines and these are my experiences.

Dear diary, i have always wanted to go into the coal mines just as my father died because i felt the call from the dust of the mines and i have never regretted a day of it, until recently.

In the anthracite coal mines where I work, we now work longer hours without overtime pay and we do not have a labor union that cannot fight for us, so some of us keep working because we need the money and do not have any other tangible skills.

Tom and a few others quit last week and they were immediately replaced. This showed us that we were not only expendable, but that the economy was so bad that people would do such a taksing work for so little pay.

if women always married men who were 2 years older than themselves, what would be the correlation between the ages of husband and wife?

Answers

The correlation between the ages of women and the men they marry would be 1.

Correlation occurs as two variables or factors are related, and therefore the change in one variable affects another. In the situation presented there are 2 variables:

The age of womenThe age of the men they married

Moreover, it is known in this situation, women are always two years younger. Let's see some examples:

Woman age                 Man age25 years old                27 years old37 years old                39 years old31 years old                 33 years old

Now, let's calculate the mean of these values

25 + 27 = 52/ 2 = 2637 + 39 = 76/2 = 3831 + 33 = 64/ 2 = 32

These values have a common factor, in all cases, the difference between any of the variables and the mean is 1, which implies the correlation is also 1.

For example: 26 that is the mean of the first example equals 25 + 1 = age of the woman and 27-1 age of the man.

International Strategy is a plan that guides the way firms make fundamental choices about developing and deploying scarce resources internationally, including what products or services to offer, which markets to enter, and ways to compete.

What is International Strategy?

The initial step in most organizations' global development plans is typically an international strategy, which involves exporting or importing goods and services while keeping a head office or offices in their home nation. There is no one method that works for all business ventures that involve global expansion.

The most effective technique is transnational, but it's also the most complicated in terms of interactions and communications. We can better grasp the connections between regional offices and corporate headquarters thanks to the graphic representation of the four basic models for worldwide strategy.

The Persian Wars: How the Greeks Won The Persian Wars were a series of conflicts fought between the Greek states and the Persian Empire from 500-449 BC. It started in 500 BC, when a few Greek city-states on the coast of Asia Minor, who were under the control of the Persian Empire, revolted against the despotic rule of the Persian king Darius. Athens and Eretria in Euboea gave aid to these Greek cities but not enough, and they were subdued by the Persians. The Persians became determined to conquer Hellas and make Athens and Eretria pay for helping the Ionian cities. In 492 BC, the first Persian invasion had its fleet crippled by a storm before it could do any damage. King Darius sent another Persian expedition in 490 which destroyed…show more content…

The great Athenian general Miltiades came up with a shrewd battle plan. He decided to thin out the ranks in the center of the phalanx to strengthen the wings. During the battle, the Greek wings crushed the Persian wings and forced them to retreat. At the same time, the Persians in the middle managed to break through the weakened center of the phalanx. Instead of pursuing the retreating Persian wings, the Greek wings moved backward to attack the Persians that had broken through the Greek defenses. The Greek center then turned around so that they had the Persians surrounded. The Persians were slaughtered (5). According to the Greek historian Herodotus, the Persians lost 6400 men while te Greeks lost only 192 (4). While the phalanx ruled on the land, the trireme ruled on the sea. The trireme was a type of warship which could be seen for the first time in the Mediterranean during the sixth century BC. The trireme completely changed war at sea. In former days sea battles were mostly fought out by soldiers who jumped from one ship onto the other. But with the introduction of the trireme the emphasis came on the battle between the ships. The trireme had a battering-ram with which it would ram opposing ships and attempt to sink them. The keel was 40 meters long and stuck out 3 meters at the front, where it was armored with bronze plates.

Of the 195 recognized countries, how many have had women as leaders?

Answers

Of the 195 recognized countries, only 70 had women as leaders. In the year 2021, only 24 countries have a woman in power, and according to UN Women, considering the present moment, gender equality in these high positions will not be achieved by women in the next 130 years.

As examples of women in power today, we can cite:

German Chancellor Angela Merkel, the only woman at the head of a country in the G7.

New Zealand Prime Minister Jacinda Ardern is popular for her administration, particularly in fighting the pandemic.

Therefore, at current rates, out of the world population of 7.8 billion people, there are only 500 million people who have a female head of government.

To reduce the disparity between men and women in power, it is necessary to establish political will in women across the world, creating fronts for female representation and gender equality.
