air pollution affects the environment, and it has many causes. some types of pollution can be prevented. classify these items as being a cause, an effect, or a prevention method for pollution.

Burning of fossil fuel-cause

Using electric cars- prevention

using aerosols= Cause

Smog- Effect

Loss of ozone layer=Effect

Acid rain- Effect

Smog-reducing filter- prevention

Volcanic eruption- cause

Explanation :

Air pollution cause items : it is defined as that items which made air polluted.

Air pollution effect items: it is defined as that items that are effected by air pollution.

Air pollution Prevention items : It is defined as that items which decrease in air pollution or prevent air to be polluted.

We are given following items

Burning of fossil fuel

Using electric cars

Using aerosols

Smog

Loss of ozone layer

Acid rain

Smog reducing filter

Volcanic eruption

Burning of fossil fuel: It is a cause of air pollution because when it burns then the smoke will cause the air and it makes air polluted.

Using electric cars- It is a prevention of air pollution because when we uses electric cars then no smoke out from vehicle then the air will be fresh and no polluted. Hence, it  prevent air to be pollute.

Using aerosols:It is used in perfumes, insecticides spray etc.  It is also cause of air pollution because it made air polluted.

Smog : It is mixture of  smoke and fog. It is also cause air pollution.

Loss of ozone layer: it is a effect of air pollution.Air pollution effect the ozone layer therefore, hole is created in ozone layer and damage the ozone layer.

Acid rain: It  is contain sulphur and nitrogen oxides  which combine with atmospheric water and produce acids. It is effect of air pollution.Because when fossil fuel burns then the gases emit from burning of fossil fuels combine with atmospheric water and produce acid rain.

Smog reducing filter: It is prevention of air pollution. Because it prevent air to be polluted.It reduce the air pollution.

Volcanic eruption:It is occurs when hot substances comes out from interior of  earth's surface  such as lava,rocks, gases etc. It is also cause an air pollution.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
