Option : a. 0.132 y-1
Correct Answer - 5.9kg,1149kg
Correct Answer - 20.8hr.
Correct Answer - (a) `Z_(A)-Z_(B)=4;A_(A)-A_(B)=4` (b) `(9N_(0))/(2)` (c) 6 hr
Correct Answer - (a) `(1)/(9)` (b) 1215s
Correct Answer - 680y
Correct Answer - (a)`(dN_(2))/(dt)=-lambda_(2)N_(2)+lambda_(1)N_(1)^(0)e^(-lambda_(1)t)` (b) `(A_(2))/(A_(1))=(lambda_(2))/(lambda_(2)-lambda_(1))` (c) `((1)/(lambda_(2)-lambda_(1)))ln((lambda_(2))/(lambda_(1)))`
Correct Answer - [0.19%]
Correct Answer - `[beta^(+), 64 min]`
Correct Answer - `[(i)" "eta r[E_(1)+E_(2)(1-e^((t log 2)/T))], (ii)" "eta r(E_(1)+E_(2))]`
Correct Answer - `[38 xx 10^(6) yrs]`
