GENERAL KNOWLEDGE

Detailed explanation-1: -The isotope Carbon-14 has a half-life of 5, 730 years.

Detailed explanation-2: -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-3: -The half-life for the decay of carbon-14 is 5730 years. Present-day carbon (in living matter) gives 15.3 disintegrations of 14C per minute per gram of total carbon. An archaeological sample containing carbon was dated by analysis of its radioactive carbon.

Detailed explanation-4: -The half life of carbon-14 is 5730 years. Radio active C^14 The half-age of 5730 years is in the sample C^14 25% of the remaining time will be spent. In a sample of rock the amount of radioactive carbon is 6.25%.

Detailed explanation-5: -The half-life of C-14 is 5, 730 years. If an excavated sample of plant or animal origin from an archaeological site had a measured activity of 7 disintegrations per minute (dpm), the age of the sample could be fixed at about 5, 730 years ± 40 years. At 3.5 dpm, the age would be about 11, 640 years and so on.
