Carbon 14 is a radioactive isotope of carbon, the most common isotope of carbon being carbon 12. Carbon 14 is created when cosmic ray bombardment changes nitrogen 14 to carbon 14 in the upper atmosphere. The resulting carbon 14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis. Animals acquire carbon 14 by eating plants. When an animal or plant dies, it ceases to take on carbon 14, and the amount of isotope...

Because the slopes of your plots are the negative of the decay constant, you can use the equation derived in Part 1 to calculate the half life of hydrogen-3 and carbon-14. Show your work for the calculation below. The number of radioactive particles is governed by the equation: N(t)= N0e−λt where N(t) is the number of radioactive particles after time t, N0 is the original number of particles, and λ is the decay constant. Show that the half life (the...
