For a radioactive material, half-life is `10` minutes. If initially there are `600` number of nuclei, the time taken (in minutes) for the disintegration of `450` nuclei is.

For a radioactive material, half-life period is 600s. If initially there are 600 number of molecules, find the time taken for disintegration of 450 molecules and the rate of disintegration.

Consider a radioactive material of half-life 1.0 minute. If one of the nuclei decays now, the next one will decay

Consider a radioactive material of half-life 1.0 minute. If one of the nuclei decays now, the next one will decay

A radioactive sample has a half-life of 10 minutes. If 64 nuclei are contained in the sample the number of nuclei that would decay after 50 minutes is

Half lives of two radioactive nuclei A and B are 10 minutes and 20 minutes respectively, If initially a sample has equal number of nuclei, then after 60 minutes, the ratio of decayed numbers of nuclei A and B will be :

Half lives of two radioactive nuclei A and B are 10 minutes and 20 minutes, respectively. If, initially a sample has equal number of nuclei, then after 60 minutes, the ratio of decayed numbers of nuclei A and B will be:

A radioactive nulei has half-life of 1.0 minute. If one of the nuclie decay now, the next nuclei will decay after:

Half-lives of two radioactive elements A and B are 20 minutes and 40 minutes respectively. Initially, the samples have equal number of nuclei. After 80 minutes, the ratio of decayed numbers of A and B nuclei will be :

Half-lives of two radioactive elements A and B are 20 minutes and 40 minutes respectively. Initially, the samples have equal number of nuclei. After 80 minutes, the ratio of decayed numbers of A and B nuclei will be
