Answer:
it's 60
Explanation:
Im only gathering this information from the little information you have provided
Answer:
The very warm ocean waters warm the air above them and evaporate very large amounts of water vapor. This water vapor is the fuel for a hurricane as it strengthens via the latent heat released by condensation of the vast amounts of water vapor.
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
Deforestation can represent the impact that colonialism had on the region
Answer: Option A
<u>Explanation:</u>
Colonialism is the colonizing of a country by some other country which was more powerful and had more authority. Colonies are made because the powerful countries search for natural resources, wealth, precious items in their colonies.
These colonies are also a place for raw material or for increasing trade of the finished goods of the country. All this leads to exploitation of the colonies also leading to deforestation where colonies have to cut down their trees and damage the environment for the benefits of the colonists.
Answer:
It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it's more abundant and it stays in the atmosphere much longer. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise
