sunlight helps in the process of photosynthesis,
Explanation:
photosynthesis is the process by which plants makes there own food using light in animals sunlight is important because it gives vimatin D which is responsible for strong born formation
The half-life of Carbon-14 is 5760 years.
<span>For carbon-14 to have decayed down by a factor of 12, we know between 3 and 4 half-lives must have elapsed. Since 4 half-lives is only 23,000 years, the sample is considerably younger than a dinosaur bone. (Unless we assume it's been contaminated with modern carbon, in which case, any age calculation based on carbon-14 is worthless.) </span>
<span>The decay equation is y = ae^(-0.0856t) with t in days. </span>
<span>To find the half-life, we solve for t such that y/a = 0.5. </span>
<span>0.5 = e^(-0.0856t) </span>
<span>Take natural logs of both sides: </span>
<span>-ln(2) = -0.0856t </span>
<span>-0.6931 = -0.0856t </span>
<span>Divide both sides by -0.0856... </span>
<span>8.096 = t </span>
<span>The half-life is 8.096 days.</span>
Answer:
A geologist is someone who is involved in the study of the outer layer of the earth's crust. A paleontologist, on the other hand, looks at fossil remains on many types of organisms on the earth's surface. Paleontology is the study of primitive life, including plant and animal organisms, fungi, bacteria, etc
