(i) Explain the term half life. (ii) Explain how radioactive carbon dating works . (iii) The shroud of Turin is reputedly the burial garment used to wrap the body of Jesus 2000 years ago. A sample of the Shroud of Turin contains carbon 14 (C14). The half life of C14 is 5730 years and atmospheric C14 give 12 decays per minute per gram. An archaeologist measures an average decay rate from the shroud sample to be 1.5 decays per minute. Show by calculation whether this is consistent with the Shroud dating from the time of Jesus. (

Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years....

Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years. Measuring the amount of this isotope left in the remains of animals and plants is how anthropologists determine the age of samples. Example: The skeletal remains of the so-called Pittsburgh Man, unearthed in Pennsylvania, had lost 82% of the C-14 they originally contained. Determine the approximate age of the bones assuming a half-life of 5730. (a) 14,000 years (b) 15,000 years (c) 17,000 years...

c. Diffusion. i. Define it, ii. Explain how it works, iii. Give 3 examples involving firms that have lead diffusion of some innovation and why these represent good examples of diffusion, iv. Discuss how diffusion might be affected by a slow growth / no growth economy. 1. Since diffusion is not free, how might it be impacted by economies that are not growing or only growing slowly?

Nuclear disintegration and carbon dating. a) The rate of decay of a radioactive nuclide is proportional to the number of nuclei N present at time t, where the proportionality constant is given by the decay constant λ: dN dt = −λN Derive an expression for the number of nuclei as a function of time N, using N0 as the number of nuclei that are present initially (at t = 0). b) Derive the relationship between the half-life T1/2 and the...

The half-life of a radioactive isotope represents the average time it would take half of a collection of this type of nucleus to decay. For example, you start with a sample of 1000 Oxygen-15 (15O) nuclei, which has a half-life of 122 seconds. After 122 seconds, half of the 15O nuclei will have decayed into Nitrogen-15 (15N) nuclei. After another 122s, half of the remaining Oxygen nuclei will have also decayed, and so on. Suppose you start with 3.71×10315O nuclei...
