The radioactivity of a sample is `A_1` at time `t_1` and `A_2` at time `t_2` If the mean life of the specimen is `T`, the number of atoms that have disintegrated in the time interval of `(t_2 - t_1)` is :

The radioactivity of a sample is R_(1) at a time T_(1) and R_(2) at time T_(2) . If the half-life of the specimen is T, the number of atoms that have disintegrated in the time (T_(2) -T_(1)) is proporational to

The radioactivity of a sample is R_(1) at a time T_(1) and R_(2) at time T_(2) . If the half-life of the specimen is T, the number of atoms that have disintegrated in the time (T_(2) -T_(1)) is proporational to

The radioactivity of a sample is R_(1) at a time T_(1) and R_(2) at a time, T_(2) If the half-line of the secimen is T , the number of atoms that have disintergrated in the time (T_(2) - T_(1)) is proportional to:

The radioactivity of sample is R_(1) at a time T_(1) and R_(2) at a time T_(2) . If the half -life of thespeciman is T, the number of atoms that have disintegrated in the time (T_(2)-T_(1)) is equal to :

The radioactive of a sample is R_(1) at a time T_(1) and R_(2) at a time T_(2) . If the half-life of the specimen is T , the number of atoms that have disintegrated in the time (T_(2)-T_(1)) is equal to (n(R_(1)-R_(2))T)/(ln4) . Here n is some integral number. What is the value of n?
