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

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

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

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

If in 3160 years, a radioactive substance becomes one-fourth of the original amount, find it’s the half-life period.

If in 3160 years, a radioactive substance becomes one-fourth of the original amount, find it’s the half-life period.

After 20 min, the amount of certai radioactive substance disintegrate was 15/16 original amount. What is the half-life ofg the radioactive substance?
