Detailed explanation-1: -The half-life of carbon-14 is 5730 years. Therefore, 5730 years after being cut from a tree, a piece of wood will have 50.0% of the carbon-14 that it had originally.

Detailed explanation-2: -5, 730 years; The graph shows that 50 percent of the carbon-14 atoms have decayed after 5, 730 years, so 5, 730 is the half-life of carbon-14. 2.

Detailed explanation-3: -C has a half-life of 5, 730 years. In other words, after 5, 730 years, only half of the original amount of 14C remains in a sample of organic material. After an additional 5, 730 years–or 11, 460 years total–only a quarter of the 14C remains. The amount of 14C remaining is used to determine the age of organic materials.

Detailed explanation-4: -Carbon 14 is a common form of carbon which decays exponentially over time. The half-life of Carbon 14, that is, the amount of time it takes for half of any amount of Carbon 14 to decay, is approximately 5730 years.

Detailed explanation-5: -The Carbon 14 Dating Equation It can simply be written that the percent remaining equals 100% times 1/2 raised to the n power. N is simply the number of half-lives.
