6. The half-life for the day of carbon-14 is 5.73x10 years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of wood from an archeological dig is measured to be 1.9x103 Bq. The acitivity in a similar- sized sample of fresh wood is measured to be 7.8x103 Bq. Calculate the age of the artifact. Round your answer to 2 significant digits. rate kN kIn 2 (ICi-3.7x1010 Bq) 1/2

1) The half-life of carbon 14 is 5600 years. Compute the rate of decay (constant ?) for this radioactive isotope (5 marks) 2) Traces of burnt wood along with ancient stone tools in an archaeological dig in Spain were found to contain approximately 10% of the original amount of carbon 14. Using the value of the constant ? from part 1), calculate when the tree was felled and burned.

An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...

10 The half life for the radioactive decay of rubidium-87 to strontium-87 is 4.88 x 10 years. Suppose nuclear chemical analysis shows that there is 0.271 mmol of strontium-87 for every 1.000 mmol of rubidium-87 in a certain sample of rock. Calculate the age of the rock. Round your answer to 2 significant digits. Ar years x10

Carbon-14 is a radioactive element with a half-life of about 5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14. We are interested in the time (years) it takes to decay carbon-14. (A) Find the value k such that P(x < k) = 0.6. (Round your answer to two decimal places.)
