1.In a radioactive material the activity at time t1t_1t1 is A1A_1A1 and at a later time t2t_2t2, it is A2A_2A2. If the decay constant of the material is λ\lambdaλ, thena.A1=A2e−λ(t1−t2)A_1 = A_2 e^{-\lambda(t_1 - t_2)}A1=A2e−λ(t1−t2)b.A1=A2eλ(t1−t2)A_1 = A_2 e^{\lambda(t_1 - t_2)}A1=A2eλ(t1−t2)c.A1=A2(t2/t1)A_1 = A_2 (t_2/t_1)A1=A2(t2/t1)d.A1=A2A_1 = A_2A1=A2Login to continueOnly logged in users canattempt or see the solution.
