2. What human activity produces the majority of these gases in the U.S. 3. In a natural environment, what contributes to surface

mash [69]

Answer:

Human activity produces Carbon monoxide and dioxide, Sulphur and other pollutants.

Explanation:

Human activity produces various gases in the U.S like dust and other harmful chemicals like carbon dioxide and methane and nitrogen oxides as the industry produces 22%, transport produces 29% and electricity produce 28% of harmful toxin and gases that release every year in the air.

Total alkalinity is affected by environmental factors like acid rains overtimes. Due to increased use of pollutant gases and continuous release of large matter in the air that over time destroys the oxygen content from river lakes and harms the vegetation cover.

Acidic rain precipitation usually takes in the form of rain which has high acid components like sulfur and nitrogen oxides that react with the water molecules to form. this train consists of a mixture of sleet fog and dry acidifying particles that can break through the buildings.

Thus in 1970 USA made an acid deposition act due to the increased emission rates of industrial pollutants. Beef, cheese, pork and lamb substance were found in this artificially induced rain. Many fish tend to die due to the river becoming acidic for them to survive.

Which of the following country demographics would be used to explain the need for the pronatalist policies shown?

Papessa [141]

Answer:

A country with a birth rate of 11, a death rate of 13, and a rate of natural increase of -0.2, legislates tax credits for working parents.

Explanation:

In simple words, Pro-natalist initiatives are initiatives developed in order to improve a region's birth level . They are present in nations with either relatively sluggish natural growth or environmental decline, and in places with communities that are ageing.

Thus, from the above we can conclude that the correct option is B.

How many times further is it from the sun to alpha centauri than from the sun to jupiter?

MAXImum [283]

The Alpha Centauri binary stars are 4.3 light years from the Earth; the Earth to the Sun is 0.00001581 light years in distance, and from the Sun to Jupiter is 0.00008229 light years.

Therefore (4.3 + 0.00001581) / 0.00008229 = 52254.41 times further

Given that a circle has a radius of 4inches and then a radius of 12inches after it has expanded. Given that the formula for a ci

nlexa [21]

Answer:

Rate of change = 3π or 9.43

Explanation:

Given the following data;

Initial radius, R1 = 4 inches

Final radius, R2 = 12 inches

To find the rate of change;

First of all, we would determine the area of the circle.

Mathematically, the area of a circle is given by the formula;

Area of circle = πr²

For initial radius, R1;

Area of circle, A1 = πR1²

Area of circle, A1 = 4π square inches

For final radius, R2;

Area of circle, A2 = πR2²

Area of circle, A2 = 12π square inches

Now, we can find the rate of change;

Rate of change = A2/A1

Rate of change = 12π/4π

Rate of change = 3π (in terms of pie).
