Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730

On Earth's surface, less direct and less intense solar radiation are received by the<em> poles.</em>
Answer: Option 2
Explanation:
Various parts of Earth's surface get different measures of sunlight. The part which is closer to the sun receives more radiation than the part which is far away.
The Sun's beams strike Earth's surface most <em>directly</em> at the<em> Equator </em>as it is near to the sun when compared to the<em> poles</em> in which it strikes the surface at an <em>inclination</em>.
