Explanation:
Yes when fossil fuels are burned they release the carbon dioxide locked inside of them
that is why fossil fuels are a big source of global warming and we will eventually run out of fossil fuels
Answer:
Answer. The more an experiment is repeated, with the same outcomes, the more biased it becomes
Explanation:
Answer:
t= 3886.18 years old
Explanation:
Whenever an animal dies de C14 and N14 begin to disintegrate in such a way that the proportion between C14 and C12 decreases, with a semi-disintegration period of 5.730 years, T. To get to know how long it takes an element to disintegrate, we must use this semi-disintegration period, which is the time it takes until the amount of the element is reduced to its half.
We can find the age of the fossil, t, by using the next formula:
t = - (T x ln (C14))/ ln (2)
t = - (5730 x ln (0.625)/0.693
t= - (-2693.12)/0.693
t= 3886.18
