How can carbon dioxide be considered a pollutant when it is a natural component of air?

High levels of acts as pollutant in the atmosphere.

Explanation:

Carbon dioxide is a natural component of air. It is produced by the human body metabolism and by other factors. However, concentrations reaching above normal levels is considered to be as a pollutant.

Carbon dioxide is produced as a byproduct of many industrial and commercial chemical synthesis. This emission directly reaches in the air and causes high levels of concentration in the atmosphere.

High levels of causes greenhouse effect, acid rain as well as global warming and thus, it is considered to be as a pollutant.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
