Find The Surface Area Of Each Figure. Round Your Answers To The Nearest Hundredth, If Necessary.

Answers

Answer 1

Answer:

Surface area of the given figure = 246.6 ft²

Explanation:

Surface Area = Lateral Surface Area + Area of Base

Now,

Base is a square

Area of Square = (9)² = 81

Now,

Lateral surface area = (1÷2)×(4×9)(9.2)

                                  = (1÷2)×(36)(9.2)

                                  = (1÷2)×(331.2)

                                  = 165.6

So,

Surface Area = 165.6 + 81

                      = 246.6

∴ we get

Surface area of the given figure = 246.6 ft²

Since the amount of pollution emitted into the air is a very small fraction of the total material in the atmosphere, why do we have air pollution problems.

[tex] \huge \mathtt \pink{Answer}[/tex]

The causes of air pollution are -

★ The burning of fossil fuels

Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum for energy in power plants, and other factory combustibles is one the major cause of air pollution.

★ Agricultural Activities

Ammonia is a very common byproduct of agriculture-related activities and is one of the most hazardous gases in the atmosphere. The use of insecticides, pesticides, and fertilizers in agricultural activities has grown quite a lot. They emit harmful chemicals into the air and can also cause water pollution.

★ Waste in Landfills

Landfills are land areas in which waste is deposited or buried. These deposited or buried wastes generate methane. Methane is a major greenhouse gas that is highly flammable and very hazardous.

★ Exhaust from factories and industries

Manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air, thereby depleting the quality of air.

Manufacturing industries can be found at every corner of the earth, and there is no area that has not been affected by it. Petroleum refineries also release hydrocarbons and various other chemicals that pollute the air and also cause land pollution.

★ Mining Operations

Mining is a process wherein minerals below the earth are extracted using large equipment. During the process, dust and chemicals are released in the air causing massive air pollution.

This is one of the reasons which is responsible for the deteriorating health conditions of workers and nearby residents.

Most of the  pollutants are in gaseous state hence they can easily diffuse to anywhere in the nearby atmosphere. Therefore, the even a small fraction of the pollution make considerable problems.

What is air pollution ?

Chemicals or other airborne particles that are harmful to plants, animals, and people collectively constitute air pollution. It also harms structures. There are numerous types of air pollutants.

These could be gases, spheres of solid matter, or drops of liquid. The various methods that pollution reaches the Earth's atmosphere are numerous.

The majority of air pollution is caused by humans and manifests as emissions from factories, vehicles, aircraft, or aerosol cans. Smoke from other people's cigarettes is likewise regarded as air pollution. Anthropogenic sources refer to these man-made pollution causes.

The pollutants can generate secondary pollutants which leads to more problems and spread into more sources. Therefore, irrespective of the amount of fraction of pollutants, they create significant air pollutions.

How can you predict the effects of a change in matter or energy availability on ecosystems?

Answers

You can deprive it, that’s a possibility
You could make a hypothesis based off of past changes in ecosystems, like many say you shouldn’t overhunt based off of what happened at Yellowstone. You could also factor the current conditions of the ecosystem (ex-geography, latitude, amount of rainfall, elevation, available species etc) and figure out the conditions of which it’s running on. Ecosystems are complex bio-diverse areas and they go through countless natural and man-made changes throughout the years, but usually find ways to adapt.
