Hope it will work. Encourage me by thumbs up.
5. A palaeontologist claims to have found a Woolly Mammoth fossil who lived 20,380 years ago....
1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
Using Python 3... Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...
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)...
Question 71 pts What is an isotope? Group of answer choices An atom that has more or fewer neutrons than it typically does An atom that has double the protons of a stable atom A nucleus of an atom that has split during the decay process An atom that has more or fewer electrons than it typically does Flag this Question Question 82 pts When the radiometric clock starts ticking in zircon minerals, there is 100% of the unstable radiometric...
