After 2 hours, a radioactive substance becomes `((1)/(16))^(th)` of original amount. Then the half life (in min) is

After 2 hr the radioactive substance becomes 1/16 th of original amount. The t_(1//2) in minutes is

Radioactive substance becomes 1/16th of original in 80 minutes. find half life

A radioactive substance decays to (3)/(4) th of original value in 2h. The half-life of the substance is

After 2 hours the amount of a certain radioactive substance reduces to 1//16^(th) of the original amount (the decay process follows first-order kinetics). The half-life of the radioactive substance is
