Answer:
11460 years
Explanation:
Let N₀ be the initial amount of carbon present. After one half-life, its value is N₀/2, after two half-lives, it is N₀/4 = N₀/2². After n nalf-lives, it is N = N₀/2ⁿ.
Now, if the value of carbon-14 drops to a quarter of its initial value, then N = N₀/4.
So, N₀/4 = N₀/2ⁿ
1/4 = 1/2ⁿ
1/2² = 1/2ⁿ
Comparing the exponents, n = 2.
So the value of carbon-14 present drops to a quarter of its initial value in 2 half-lives.
Since one-half life equals 5730 years, then two-half-lives is 2 × 5730 years = 11460 years
So, it takes carbon-14 11460 years for the number of nuclei to drop to a quarter of its initial value.
