Earth's atmosphere is composed of a mixture of gases we call air. Air is mostly nitrogen (78%) and oxygen (21%), with some argon (0.93%), carbon dioxide (0.03%), ozone, watervapor, and other gases (less than 0.04% together).

d

2

m×M

Distance between two masses is increased s.t. new distance is D= 5 d

New gravitational force F

The carbon cycle is one of many biogeochemical cycles on Earth. Can you identify the main features of a biogeochemical cycle and
podryga [215]

Answer:

The carbon cycle mainly is the relationship among carbon dioxide, glucose and carbon.

Explanation:

The carbon cycle as a reference point we can say that it starts in air, with the carbon dioxide dissolved in it. Plants or phytoplancton can absorbed it to transform into glucose or other organic compound useful for plants of plancton. During this process the carbon cycle is closely related with oxygen cycle and metabolic processes in living things.

After the carbon is absorbed it can be regenerating as carbon dioxide by bacteria or animals to the air after getting the sufficient carbon for the glucose structure or another organic compound necessary for these living things.

The other way of carbon, is that can be deposit in soil as carbon and with time can be transformed into oil by bacteria but in an anaerobic environment not in an aerobic environment.

A dog runs 68 meters from one corner of a rectangular park to the opposite corner . If the length of the park is 60 meters , wha
rewona [7]

Answer:

32 meters

Explanation:

You use the formula a^2 + b^2 = c^2.

Plug in the length and hypotenuse.

60^2 + b^2 = 68^2

Simplify and Solve:

3600 + b^2 = 4624

4624 - 3600 = b^2

1024 = b^2

Sqrt 1024 = 32

b = 32

If the temperature of a gas increased from 100 K to 200 K and the volume of a gas decreased from 20 L to 10 L, what is the new p
dezoksy [38]

Answer:

B. 400 kPa

Explanation:

the pressure increases, when the temperature increases. and it increases, when the volume decreases.

both cases happen here, each with the factor 2.

so, the pressure increases by the factor 2×2 = 4.

4×100 = 400 kPa
