1. The nucleus 14C (half life 5730 y) is used in radiocarbon dating to determine the age of previously living material.
(a)A certain sample of wood currently shows a decay rate of 35.0 decays/s of
14C The wood is taken from a structure that was built from a
tree that was cut 7,000 years ago. What would have been the 14C
decay rate of this wood sample when the tree was cut?
(b) Find the total binding energy (in MeV) of 14C
(c) Suppose it were possible to form a nucleus of 14C by colliding two 7Li nuclei. Is energy absorbed or released in this process? (Choose which one.) Calculate the energy absorbed or
released in MeV.1. The nucleus 14C (half life 5730 y) is used in radiocarbon dating to determine the age of previously living material.1.

Radiocarbon dating techniques are used to determine that a very old piece of bone emits emits about 29 B-particles per sec. If a similarly-sized sample of modern bone emits about 928 B-particles per sec, and the half-life of 14C is 5730 years, approximately how old is this bone fragment (in years)?

When a plant or an animal dies, its 14C content decreases with a half-life 5730 years. If an archeologist finds an ancient firepit containing partially consumed firewood and the 14C content of the wood is only 15% that of an equal carbon sample from a present-day tree, what is the age of the ancient site?

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,...

The answer is not 13657.8
A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.2 kg sample of carbon from the wood has an activity of 1660 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y.

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...

QUESTION 2 Radiocarbon dating is used to determine the age of organic materials. Living objects have a consistent amount of carbon-14 in their systems due to the fact that they are constantly incorporating new carbon into their systems and C-14 is being constantly generated by our atmosphere. When an organism dies, it stops incorporating C-14 into its system and the C-14 that was present undergoes a first order kinetic decay. The half life of carbon 14 is 57 15 years...
