Answer:
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
As the burning of fossil fuels and landscape alterations, such as deforestation and industrial agriculture, mobilize fossil carbon into the atmosphere, the earth's carbon cycle is pushed out of balance and climate changes. Human generated climate change is an enormous perturbation in the global carbon cycle.
Explanation:
I think through convection I forget. Plus its enclosed (and, well closed)
Answer: Option (B) is the correct answer.
Explanation:
Expression for centripetal acceleration is as follows.
a = .......... (1)
Also, we know that
........... (2)
Putting the value from equation (2) into equation (1) as follows.
a =
=
As,
a =
or,
Now, we will reduce a to . So, new value of will be equal to .
Therefore, value of new period will be as follows.
=
Thus, we can conclude that the new period is equal to .
