The carbon-14 decay rate of a sample obtained from a young tree is 17.2 disintegration per minutes per gram of the sample. Another wood sample from an object recovered at an archaeological excavation gives a decay rate of 4.39 disintegration per second per gram of the sample. What is the age of the object? The half life of C-14 is 5715 years.
