Answer:

The sample is about 34380 years old.

Explanation:

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

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

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

Where:

[tex]m_{o}[/tex] - Initial mass, in grams.

[tex]m(t)[/tex] - Current mass, in grams.

[tex]t[/tex] - Time, in years.

[tex]\tau[/tex] - Time constant, in years.

[tex]t_{1/2}[/tex] - Half-life, in years.

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

[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]

[tex]\tau = 8266.643\,yr[/tex]

[tex]t = - \tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]

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

[tex]t \approx 34380.002\,yr[/tex]

The sample is about 34380 years old.

Answer:

Explanation:

Resources may be explained as a range of products, equipment, manpower and all other things an individual or organization has at its disposal in other to function prey and effectively.

Resources may also be natural which will include all resources borne out of nature such as air, sunlight, mineral resources and all resources devoid of human doing.

Resources are required on other to ensure that an organization functions well as it will be impossible to produce without the needed help (resources). Similarly, it will be impossible to survive without the availability of nature resources as they help us breath, make money, in food production and so on.

Resources conservation involves the effective and efficient use of resources. Conservation of resources can be enhanced in ways such as :

Embracing the use of renewables : The use of renewable energy sources provides a clean choice of energy which is obtained from nature's routine. The use of solar energy frolic the sun or wind powered energy obtained from natural breeze or wind.

Embrace Recycling : Recycling involves the reuse of already used materials as a form of raw material to make new products, these ensures that optimum use of the resources at our disposal is achieved while also ensuring that we have a cleaner environment.

Use of reusable goods or materials : The large influx of onr-tine use products such as disposables and certain plastic materials has contributed to large quantities of water materials on landfills, they adoption of reusable materials which can be used over certain period of time will go a long way in controlling these waste Influx.

Answer:

b. sunny climates in summer when coal is burned to generate electric power.

Answer:

Northern Hemisphere:  Thar desert

Southern Hemisphere:  Great Australian desert

Explanation:

The BWh climate is a desert climate. It is a hot and arid climate o the deserts, as classified by the Köppen climate classification of BWh and BWk. The BWh zone falls on the hot and arid regions.

One desert in the Northern hemisphere which contains BWh climate is Thar desert in India. It is a very hot desert with very sandy and rocky surfaces.

One desert in the Southern hemisphere having BWh climate is the great Australian desert. It is a sandy desert with very less precipitation.

Explanation:

Explanation:

Weathering has deteriorated and broken up the sandstone, making it ready for destruction. Erosion occurs when ice, moisture, wind, or gravity take up and transport rocks and materials to a new location. They can't transport as much sediments if they slow down. Rock formations are where the sediment is dumped or deposited.

Explanation:

Answer:

A change in one of these variables can cause a population decrease in some living being that has the ocean as its habitat. This decrease would affect the feeding of animals that consume this living being and this will disharmonize the entire food chain of consumers above this living being.

Explanation:

Although the ocean is affected by a relatively small number of variables. These variables are essential for the maintenance of living beings within the ocean. If one of these variables is modified, in the long term, many species of living beings can be negatively impacted in an intense way, even having their survival in danger and decreasing their population density. This would be very harmful to the harmony of food chains within the ocean. That's because, as you may already know, the food chain is a feeding sequence between living beings, where one species feeds on another, which shows how one species depends on the other to survive.

Thus, if there is a change in the variables that act on the ocean and this change causes the population reduction of a species of living being. The species of animals that feed on this living being will also be affected as they will not have enough food to sustain themselves. Isss will decrease the population density of this second species, affecting the species that will feed on it, and so on.

Answer:

Answer:

We study about the sun because  

The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.

Explanation:

How does the Sun help to protect life on Earth?

It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.

Answer:

The liquid phase of most materials is less dense than the solid phase. Thus, molten rock (magam) is less dense than solid rock. When a body of magma forms deep beneath the Earth's surface, it tends to rise buoyantly like a hot air balloon rising through the atmosphere
