Explanation:

Answer:

b. inner core

Explanation:

To solve this problem let's start by listing the information given. This will help us find which option best fits the characteristics provided to find the correct answer.

characteristics of mystery layer:

i. it is solid and extremely hot

ii. it is the innermost layer of the Earth

iii. it is around 800 miles thick

Now let's go through each option to determine which best matches the characteristics.

option a

outer core

The first characteristic of the mystery layer is 'it is solid and extremely hot.' The outer core of the earth, however, is a fluid layer. Therefore, this option cannot be correct.

option b

inner core

The inner core is a solid 'ball' and is about 10,800°F. It is also the inner, or last layer, of the earth and is around 800 miles thick. Therefore, it matches all characteristics of the mystery layer so, this must be the correct answer. If you would like to be sure, I also reviewed the last two options below.

option c

crust

Because the crust is the outermost layer of the planet, it does not match the second characteristic of the mystery layer. Therefore, this cannot be the correct answer to the question.

option d

mantle

Although the mantle does match the first characteristic, it does not match the second characteristic, which requires the layer to be the innermost layer of the earth. The mantle is one of the outer layers of the earth.

Now that all options are reviewed, we have determined the best solution to the problem. The correct answer to this question is b. inner core.

Answer:

Answer:

Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption

Explanation:

Answer: They are not.

Explanation:

When it comes to molecular bonding, a single additional atom can change the characteristics of the compound. This is why Carbon Dioxide is different from Carbon Monoxide even though they both contain only Carbon and Oxygen atoms albeit in different quantities.

In this scenario the compounds described are Hematite which has two iron atoms to three oxygen atoms and Magnetite which has three iron atoms to four oxygen atoms. The presence of the different number of the same atoms made these compounds different.

The 73 g of concentrated Hydrochloric Acid was diluted by adding 144g of water. So, 18 grams atom of hydrogen are present in the dilute acid.

Methane, also known as natural gas, can be replaced with hydrogen, a clean fuel. It is the most prevalent chemical element and is thought to make about 75% of the universe's mass. Numerous hydrogen atoms can be found in water, plants, animals, and, of course, people here on earth.

Moles of HCl are -

n(HCl) = W(HCl) / M(HCl)

n(HCl) = 73/36.5

n(HCl) = 2 mol

Moles of H-atoms in HCl is -

n1 = 1 × 2

n1 = 2 mol

Moles of H2O are -

n(H2O) = W(H2O) / M(H2O)

n(H2O) = 144/18

n(H2O) = 8 mol

Moles of H-atoms in H2O is -

n1 = 2 × 8

n1 = 16 mol

Total moles of H-atoms is -

n = n1 + n2

n = 2 + 16

n = 18 mol

Therefore, 18-gram atoms hydrogen are present in dilute acid.

The exploitation of nonrenewable resources leads to the growth of social complexity. alas, human society is—in the meanwhile—depending on nonrenewable resources as its number one supply of power. approximately eighty percent of the entire quantity of strength used globally every yr comes from fossil fuels. we rely on fossil fuels due to the fact they are energy-wealthy and comparatively cheap to process.

Nonrenewable intake increases the actual GDP unexpectedly as compared to renewable electricity consumption. but, it has an 87% variant in carbon dioxide emission, which reasons deforestation and perilous impacts on human fitness and the environment.

Perhaps the maximum impact of the usage of non-renewable strength assets is the emission of greenhouse gases, especially carbon dioxide and methane, which make a contribution to weather alternatives [1]. exceptional forms of non-renewable electricity fuels emit distinctive degrees of greenhouse gases.

Based on the article, the statement that best represents the United States approach to South Korea is option C: the United States sided with South Korea because the Soviet Union had joined forces with North Korea. The correct answer is option-C.

This is evident from the article's mention of the United States' response to North Korea's invasion of South Korea in 1950. The US saw it as a threat to democracy and an opportunity for the Soviet Union to spread communism in Asia. Thus, the US immediately intervened and provided military support to South Korea to prevent the spread of communism and Soviet influence in the region.

While the US may have had reservations about South Korean leader RHEE, the primary motivation for its support was geopolitical and ideological rather than personal. The US was eager to maintain its presence in Japan and prevent the spread of communism, which is why it was willing to support South Korea despite the risks involved.

Therefore, the correct answer is option-C.

The biggest research station in Antarctica was established in 1956 and is called McMurdo Station. Although there are challenges, life in McMurdo is often more pleasant than it was for the earliest pioneers.

The station lacks the medical equipment necessary to provide adequate care. Vessel season, or just "vessel," is the time of year when supplies like food and fuel are brought in by ships once a year. During the summer, there is a weekly Sunday brunch with a smorgasbord, live egg station, hot specialties, and freshly baked pastries and desserts. There are some expired canned or dried products.

The day-long outdoor music festival Ice Stock is held in McMurdo every New Year's Eve. Burgers and hotdogs are served, and people dress up in vibrant costumes or the perennially popular animal onesie. Local bands perform throughout the afternoon and into the evening. Even though it's not always easy, McMurdo's way of life is a little more enjoyable than what the early explorers had to endure.

The future of the universe according to the law of gravitational force is governed by two possible scenarios: expansion or contraction.

According to the law of gravitational force, the future of the universe depends on the balance between the gravitational pull of matter and the expansion or contraction caused by dark energy. If the gravitational pull is strong enough to overcome the expansion, the universe will eventually stop expanding and start contracting.

This scenario is known as a "Big Crunch where the universe collapses in on itself. On the other hand, if the expansion caused by dark energy is dominant and continues to accelerate, the universe will keep expanding indefinitely. This scenario is referred to as the "Big Freeze" or "Heat Death," where galaxies drift apart, and the universe becomes increasingly empty and cold.

Answer:

The sample is about 34380 years old.

Explanation:

The amount of Carbon-14 mass diminishes exponentially in time, whose model is described below:

\(\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }\) (1)

\(\tau = \frac{t_{1/2}}{\ln 2}\) (2)

Where:

\(m_{o}\) - Initial mass, in grams.

\(m(t)\) - Current mass, in grams.

\(t\) - Time, in years.

\(\tau\) - Time constant, in years.

\(t_{1/2}\) - Half-life, in years.

If we know that \(\frac{m(t)}{m_{o}} = \frac{1.5625}{100}\) and \(t_{1/2} = 5730\,yr\), then the age of the sample is:

\(\tau = \frac{5730\,yr}{\ln 2}\)

\(\tau = 8266.643\,yr\)

\(t = - \tau \cdot \ln \frac{m(t)}{m_{o}}\)

\(t = - (8266.643\,yr)\cdot \ln \frac{1.5625}{100}\)

\(t \approx 34380.002\,yr\)

The sample is about 34380 years old.
