A radioactive nucleus A with a half life T, decays into nucleus B. At t=0, there is no nucleus B. At some time t, the ratio of the number of B to that of A is 0.3 . Then, t is given by

A radioactive nucleus A with a half life T, decays into nucleus B. At t=0, there is no nucleus B. At somewhat t, the ratio of the number of B to that of A is 0.3 . Then, t is given by

A sample of a radioactive nucleus A disintegrates to another radioactive nucleus B, which in turn disintegrates to some other stable nucleus C. Plot of a graph showing the variation of number of atoms of nucleus B vesus time is : (Assume that at t = 0, there are no B atoms in the sample)

A radioactive nucleus can decay in two different processes with half life 0.7 hr and 0.3 hr . The

Radioactive nucleus A decays into B with half-life 10sec . A also convert into C with half-life 100 sec . Find half-life of A for both emission.

Radioactive nucleus A decays into B with half-life 10sec . A also convert into C with half-life 100 sec . Find half-life of A for both emission.
