Answer:

Explanation: The atmosphere is the layer of gases around the earth. The atmosphere is composed of 78% nitrogen, 21% oxygen, and 0.9% carbon dioxide, argon, methane, ect.  The atmosphere is vitally important to support complex life, such as ourselves. There is just the right balance of gases needed for life. If there were too little oxygen, we would die. If there were to much oxygen, we would get permanent lung damage and eventual blindness. The nitrogen dilutes the oxygen in the atmosphere, because too much can cease life.

The ozone layer is located in the stratosphere, and its main role is to deflect dangerous ultraviolet rays from the sun. Without it, life as we know it would cease. Ground level ozone, however, is a pollutant and can cause death if continually exposed.

Air pressure is the weight of the atmosphere's air molecules.

Main factors that influence our weather is the sun's radiation,  earth's axial tilt, latitude and longitude, air pressure, and abundance of water.

Wind is a result of a certain rising mass of air. When air rises, air in the upper atmosphere rushes in to fill the void left by the rising air. This phenomenon is what we perceive as wind.

The dew point is the temperature at which water droplets condense to form dew.

Clouds are a result of air rising and condensing onto particles called cloud condensation nuclei. When that happens, a cloud is formed. Adiabatic cooling is also responsible for how clouds form. The main types of clouds are cumulus, stratus, cirrus, and lenticular.

Precipitation is any sort of water from the atmosphere. Precipitation can be rain, snow, hail, sleet, freezing rain, ect. For example, ocean water is always evaporating, gets stored in a cloud, and falls as precipitation. This precipitation gets absorbed as groundwater, surface runoff, ect. Fun fact: water from your fridge may have came from the ocean. You would expect it to be salty, but it isn't. Salt is too heavy to evaporate.

There are many types of air masses. The three main ones are polar, continental, and tropical.

A maritime tropical air mass is an air mass that was formed over a tropical ocean. The characteristics of the air mass would be wet and humid.

Energy is observed in two basic forms: potential and kinetic. Which of the following correctly matches these forms with a source
Travka [436]

Answer:

option C

Explanation:

The correct answer is option C

Kinetic energy is the energy which is due to the motion of body.

Potential energy is the energy due to virtue of position of the object.

option A is not true because potential energy is due the position of the body

Option B should be the potential energy not kinetic energy.;

Option D is motion of individual molecule leads to kinetic energy not potential energy.

So, the correct answer is option is the covalent bonds of a sugar molecule is potential energy because of the position of bond.

How much work is done on the electron by the electric field of the sheet as the electron moves from its initial position to a po
miss Akunina [59]

Incomplete question as the charge density is missing so I assume charge density of 3.90×10^−12 C/m².The complete one is here.

An electron is released from rest at a distance of 0 m  from a large insulating sheet of charge that has uniform surface charge density 3.90×10^−12 C/m² .  How much work is done on the electron by the electric field of the sheet as the electron moves from its initial position to a point 3.00×10−2 m from the sheet?

Answer:

Work=1.06×10⁻²¹J

Explanation:

Given Data

Permittivity of free space ε₀=8.85×10⁻¹²c²/N.m²

Charge density σ=3.90×10⁻¹² C/m²

The electron moves a distance d=3.00×10⁻²m

Electron charge e=-1.6×10⁻¹⁹C

To find

Work done

Solution

The electric field due is sheet is given as

E=σ/2ε₀

E=\frac{3.90*10^{-12}C/m^{2}  }{2(8.85*10^{-12}C^{2} /N.m^{2} )}\\ E=0.22V/m

Now we need to find force on electron

F=eE\\F=(1.6*10^{-19}C )(0.22V/m)\\F=3.525*10^{-20}N

Now for Work done on the electron

W=F*d\\W=(3.525*10^{-20} N)(3.00*10^{-2}m)\\W=1.06*10^{-21}J
