Be sure to answer all parts. Archaeologists can determine the age of artifacts made of wood or bone by measuring the amount of the radioactive isotope 14C present in the object. The amount of isotope decreases in a first-order process. If 29.3% of the original amount of 14C is present in a wooden tool at the time of analysis, what is the age of the tool? The half-life of 14C is 5,730 yr. Give your answer in scientific notation.

Be sure to answer all parts. Archaeologists can determine the age of artifacts made of wood or bone by measuring the amount of the radioactive isotope 1"C present in the object. The amount of isotope decreases in a first-order process. If 12.0% of the original amount of 1"C is present in a wooden tool at the time of analysis, what is the age of the tool? The half-life of 14C is 5,730 yr. Give your answer in scientific notation. x...

In the carbon dating process for measuring the age of objects, carbon-14, a radioactive isotope, decays into carbon-12 with a half-life of 5730 years. A Cro-Magnon cave painting was found in a cave in Europe. If the level of carbon-14 radioactivity in charcoal in the cave is approximately 16% of the level of living wood, estimate how long ago the cave paintings were made. (Hint: Let the initial amount of carbon-14 be C0. Round your answer to the nearest year.)

My Notes Ast our Teacher Scientist can determine the age of andient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 1C, with a haf-ife of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates through food chains. When a plant or animal dies, t stops replacing its carbon and the amount of1C begins to decrease through radioactive decay. Therefore,...

Question 75 5 pts Determine the age of the zircon mineral grain from a granite in the Sierra Nevada using the 14C to 14N method. The mineral has 5678814C atoms and 87655 14N atoms. The half life (T1/2) of this system is 5730 years. What is the age? Use the curve equation T = -1.4431n(f) 1. Determine Pi, initial parent amount (add Parent Daughter) 2.f P/Pi 3. Use the curve equation to solve for T (number of half lives elapsed)...
