At t=0 , number of radioactive nuclei of a radioactive substance are x and its radioactivity is y. Half-life of radioactive substance is T. Then,

Calculate the average life of a radioactive substance whose half life period is 1650 years.

If 9.0 g of a radioactive isotope has a half life period of 10 hrs. The half life period of 3.0 g of the same substance is:

If 8.0 g of radioactive isotope has a half life of 10 hours, the half life of 2.0 g of the same substance is

Calculate the average life of a radioactive substance whose half-life period is 100 years.

The relation between half-life T of a radioactive sample and its mean life tau is:

The decay constant of a radioactive sample is 1. The half life and mean life of the sample, respectively, are given by
