In a smaple of rock, the ration .^(206)Pb to .^(238)U nulei is found to be 0.5. The age of the rock is (given half-life of U^(238) is 4.5 xx 10^(9) years).

In a smaple of rock, the ration .^(206)Pb to .^(238)U nulei is found to be 0.5. The age of the rock is (given half-life of U^(238) is 4.5 xx 10^(9) years).

In an old rock, the mass ratio of ""_(92)^(238)U to ""_(82)^(206)Pb is found to be 595:103 . The age of the rock is (Mean life of ""_(92)^(238)U is T_(0) ) :

In a sample of rock the amount of radioactive carbon is 6.25%. If the half life of radioactive carbon is 5730 years then estimate the age of rock.

In an ofd rock, the mass ratio of ._(92)^(238)U to ._(82)^(206)Pb is formed to be 595:103. The age of the rock is (Mean life of ._(92)^(238)U is T_(0) ) :

In moon rock sample the ratio of the number of stable argon- 40 atoms present to the number of radioactive potassium -40 atoms is 7:1 . Assume that all the argon atoms were produced by the decay of potassium atoms, with a half-life of 2.5xx10^(9)yr . The age of the rock is
