A sample of rock from moon contains equal number of atoms of uranium and lead ( t_(1//2)" for "U=4.5xx10^(9) years). The age of the rock would be :

A sample of rock moon contains equal numbers of atoms of uranium and lead t_(1//2) for U is 4.5 xx 10^(9) years. The age of rock would be a. 4.5 xx 10^(9) years b. 9.0 xx 10^(9) years c. 13.5 xx 10^(9) years d. 2.25 xx 10^(9) years

A sample of rock moon contains equal numbers of atoms of uranium and lead t_(1//2) for U is 4.5 xx 10^(9) years. The age of rock would be a. 4.5 xx 10^(9) years b. 9.0 xx 10^(9) years c. 13.5 xx 10^(9) years d. 2.25 xx 10^(9) years

Uranium ( ""_(92)U""^(238) ) decayed to ""_(82)Pb""^(206) . The process is ""_(92)U""^(238)underset(xalpha,ybeta)to.""_(82)Pb""^(206) t""_(1//2)of U""^(238)=4.5xx10""^(9) years A sample of rock from South America contains equal number of atoms of U""^(238) and Pb""^(""^(206) .

Initially the earth was a fire-ball, slowly it has cooled to form earth crust and its different layers. At the beginning ""_(92)^(238)U was present and no ""_(82)^(206) Pb was there. With the passage of time, uranium decayed to ""_(82)^(206)Pb The decay process is : ""_(92)^(238)U underset((x alpha, y beta))to ""_(82)^(206)Pb , t_(1//2) of ""^(238)U = 4.5 xx 10^(9) yrs A sample of rock from south America contains equal number of atoms of ""^(238)U and ""^(206)Pb . The age of the rock will be :

A sample of rock from moon contains atoms of uranium and lead in the ration 1:3. Then age of rock will be (t_(1//2)"for uranium"=4xx10^(10)years) :

Uranium ._(92)U^(238) decayed to ._(82)Pb^(206) . They decay process is ._(92)U^(238) underset((x alpha, y beta))(rarr ._(82)Pb^(206)) t_(1//2) of U^(238) = 4.5 xx 10^(9) years A sample of rock south America contains equal number of atoms of U^(238) and Pb^(206) . The age of rock will be
