(a) Starting from the radioactive decay law N(t)=N0e−λt, obtain an algebraic expression that can be represented as a straight line in suitable variables.
(b) For the straight-line form derived in part (a), identify the physical meaning of the slope and the intercept.
(c) Explain, without performing any numerical calculation, how the intercept of this graph can be used to determine the initial number of undecayed nuclei in an experimental study.
