Question 8

Following equation is used in carbon dating of the artefacts:
N =   ×   where,
N = Decay rate of the artefact, expressed as disintegrations per minute (dpm)   = Decay rate of natural carbon = 14 dpm
τ = Mean life time =   =   = 8267 years
t = Age of the artefact
Calculate the age of the artefact, if the decay rate of the artefact is measured as 4 dpm

Accepted Answer

N = @#IMG-DLM& × @#IMG-DLM& ⇒ @#IMG-DLM& = @#IMG-DLM& @#IMG-DLM& @#IMG-DLM& = @#IMG-DLM& ln @#IMG-DLM& @#IMG-DLM& @#IMG-DLM& @#IMG-DLM& Plug
