A radioactive sample decays by `63%` of its initial value in `10s`. It would have decayed by `50%` of its initial value in .

A radioactive substance decays to 1/32 of its initial value in 25 days. Calculate its half life.

In one half- life time duration activity of a sample reduced to half of its initial value. total number of nuclei present are reduced to half of its initial value. number of radioactive nuclei present is reduced to half of its initial value mass of sample is reduced to half of its initial value Out of these, correct statements are

A radioactive sample decays to half of its initial concentration in 6.93 minutes. If it further decays another half in next 6.93 minutes, then the rate constant for the reaction is:

A radioactive sample decays to half of its initial concentration in 6.93 minutes. If it further decays another half in next 6.93 minutes, then the rate constant for the reaction is:

A radioactive substance decays to ( 1/10)^th of its original value in 56 days. Calculate its decay constant.

A radioactive substance decays to [1/16^(th)] of its initial quantity in 108 minutes. Find its decay constant

The activity of the radioactive sample drops to (1/64)^(th) of its original value in 2 hr find the decay constant (lambda) .
