Be sure to answer all parts. The carbon-14 decay rate of a sample obtained from a young tree is 0.264 disintegration per second per gram of the sample. Another wood sample prepared from an object recovered at an archaeological excavation gives a decay rate of 0.193 disintegration per second per gram of the sample. What is the age of the object? (The half-life of carbon-14 is 5715 years.) × 1 ol 1 years Enter your answer in scientific notation.
