Problema Solution
the half life of radioactive carbon-14 is 5700 years. how much of an initial sample will remain after 3000 years?
Answer provided by our tutors
the model for radioactive decay is:
A(t) = A0 (1/2)^(t/h)
A0 = is the initial sample
h = 5,700 years the half-life
t = 3,000 years
A = A0(1/2)^(3000/5700)
A = A0 * 0.6943
after 3000 years 69.43% of the intial amount will remain.
