Understand how decay and half life work to enable radiometric dating.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.$$ So either the answer is that ridiculously big number (9.17e7) or 30,476 years, being calculated with the equation I provided and the first equation in your answer, respectively. Learn about different types of radiometric dating, such as carbon dating.It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.
Now, take the logarithm of both sides to get $$ -0.693 = -5700k, $$ from which we can derive $$ k \approx 1.22 \cdot 10^.
(Whatever you're being treated for is the greater danger.) The half-life is just long enough for the doctors to have time to take their pictures.
The dose I was given is -younger copy of an earlier document (in which case it is odd that there are no references to it in other documents, since only famous works tended to be copied), or, which is more likely, this is a recent forgery written on a not-quite-old-enough ancient parchment.
Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.
When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.
