The half - line period a radioactive element `X` is same as the mean life time of another radioactive element `Y`. Initially both of them have the same number of atoms. Then:

The half - life period of a radioactive element x is same as the mean life time of another radioactive element y Initially both of them have the same number of atoms. Then,n

Read the following : (i) The half-life period of a radioactive element X is same as the mean-life time of another radioactive element Y. Initially both of them have the same number of atoms. Then Y will decay at a faster rate the X. (ii) The electron emitted in beta radiation originates from decays of a neutron in a nucleus (iii) The half-life "of"^( 215) At is 100 ms. The time taken for the radioactivity of a sample "of"^( 215) At to decay to 1//16^(th) of its initial value is 400 ms. (iv) The volume (V) and mass (m) of a nucleus are related a V prop m. (v) Given a sample of Radium - 226 having halflife of 4 days. Find the probability, a nucleus disintegrates within 2 half lives is 3/4. Select the correct code for above.

The half-life period of a radioactive element x is same as the mean life time of another radioactive element y. Initially, both of them have the same number of atoms. Then, (a) x and y have the same decay rate initially (b) x and y decay at the same rate always (c) y will decay at a faster rate than x (d) x will decay at a faster rate than y

The half-life period of a radioactive element x is same as the mean life time of another radioactive element y. Initially, both of them have the same number of atoms. Then, (a) x and y have the same decay rate initially (b) x and y decay at the same rate always (c) y will decay at a faster rate than x (d) x will decay at a faster rate than y
