4. What type of smog do we experience in the United Sta5. Why is it harmful?6. What is one resultof air pollution?7. Rain that contains more acid than normal is called8. How does acid rain harm our environment?How are Americans improving air quality?
Answers
5. It is harmful because brown smog is composed of NOx's which react with water vapor in the atmosphere and create acid rain.
6. One result of air pollution is acid rain.
7. Acid rain.
8. Acid rain harms our environment by decreasing the pH of the soil which can harm plant life and bacteria, disrupting the ecosystem.
9. Americans are improving air quality by passing laws such as the Clean Air Act of 1990 which puts limits on the amount of air pollutants cars, factories, ect can release into the atmosphere.
Side note: if you enjoy learning about this sort of thing or how humans impact the world, and haven't taken AP Environmental Science you totally should. It's a very eye opening class and I enjoyed it very much this year!

The ball only accelerates during the brief time that the club is in contact
with it. After it leaves the club face, it takes off at a constant speed.
If it accelerates at 20 m/s² during the hit, then
Force = (mass) x (acceleration) = (0.2kg) x (20 m/s²) = 4 newtons .
F = 0.2 * 20 = 4 Newtons

Convention occurs when the substance being heated begins a cycle of cooling and heating. the heat goes to the opposite side of which the substance is being heated and the substance is cooled on the corresponding side, this cycle continues until the heat source is extinguished.
Radiation occurs when the heat of a substance is being transferred via gas form. Ex: sunburn.

Protons and electrons are the two equally abundant particles in an atom.
The atom's nucleus contains protons, which are subatomic particles with a positive charge. A +1 positive electric charge permeates each proton.
An atom's nucleus is surrounded by electrons, which are subatomic particles with a negative charge. An electric charge of -1 is carried by each electron.
The number of protons in the nucleus of a neutral atom is equal to the number of electrons encircling the nucleus. The atom becomes electrically neutral when the balance of positive and negative charges results in a net electric charge of zero.
An atom with the atomic number 6 for carbon, for instance, contains six protons and six electrons. Similar to this, an atom of sodium, which has an atomic number of 11, contains 11 protons and 11 electrons.
An atom is stable and maintains its distinctive chemical properties because it has an equal number of protons and electrons.
