- Potassium-argon dating is used to measure the age of rocks formed from cooled lava by determining the fraction of the original 40K remaining in a sample from the ratio of 40K:40Ar. Unusually, potassium-40 decays into both 40Ca (89.1% of the time) and 40Ar (10.9% of the time) with a half-life of 1:248 x 10^9 years.1. What is the calculated age of a sample in which the faction of 40K remaining was found to be 0.0043?2. Is this result physically plausible?The number of radioactive atoms in a sample decay as the emission of radiation proceeds and this may be described by an exponential decay N(t) = N0exp(-t/τ) where τ is the decay time. What is the decay time τ if the half-life t1/2 = 3hrs? Select one: a. 8.15 hours b. 90 mins. c. 260 mins. d. 3 hours.Needs Complete solution. Plz.
