An artifact is found in a desert cave. the anthropologists who found this artifact would like to know its age. they find that the present activity of the artifact is 9.25 decays/s and that the mass of carbon in the artifact is 0.100 kg. to find the age of the artifact, they will need to use the following constants: 1. r = 1.2 x 10^{-12},
2. m_a = 2.32 x 10^{-26} kg,
3. lambda = 1.21 x 10^{-4} year^{-1}.
what is the age of the artifact? be mindful of the units.
