The half-life of carbon-14 is 5730 yr. Archaeologists discovered a small wooden statue during a recent excavation. If the carbon-14 that remains in the bowl is 74% that of a living tree, how old is the statue? Select one: a. 1.7 × 103 yr b. 2.5 × 103 yr c. 4.2 × 103 yr d. 6.1 × 103 yr

Typing The Answer Is Mandatory The half-life of carbon is 5700 years. A substance was found that originally contained 40 grams of carbon-14. It now contains 10 grams of carbon-14. Predict how old the substance is. Explain how you arrived at this prediction.

Carbon 14(c) dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of 14c absorbed by a tree that grew several centuries ago should be the same as the amount of absorbed by a tree growing today. A piece of ancient charcoal contains only 14% as much radioactive carbon as a plece of modern charcoal. How long ago was the tree burned to make the...

Some fossil bones containing 1/32 of their original amount of carbon-14 are found. How many half-lives have passed? How old are the bones? (HINT: The half-life of carbon-14 is 5,730 years. If 1/8 of the original amount of carbon-14 was present, 1/8 = 1/23 or 1/(2x2x2), therefore 3 half-lives would have passed and therefore, the bones would be 5,730 years x 3 = 17,190 years old)

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,...
