1. The half-life for the (first-order) radioactive decay of 14C is 5730 yr (it emits a β ray with an energy of 0.16 MeV). An archaeological sample contained wood that had only 72 percent of the 14C found in living trees. What is
Hi! I'm having lots of trouble figuring these two out.....if you could help that would be great- thanks!! 1. The half-life for the (first-order) radioactive decay of 14C is 5730 yr (it emits a β ray with an energy of 0.16 MeV).
Carbon-14 has a half-life of about 5,600 years. Archaeologists analyze a piece of wood found at an ancient village site and determine that, of he initial 100 grams of Carbon-14 in the wood, onl 3.125 grams are left. How old is the
A piece of wood found in an ancient city has a carbon-14 to carbon-12 ratio that is one-eighth the carbon-14 to carbon-12 ratio of a tree growing nearby. How old is the piece of wood? (The half-life of carbon-14 is 5,715 years.)
