Two radioactive substances, A and B, have different half-lives. Substance A has a half-life of 5.80 s and substance B has an unknown half-life. Initially, there is 2.00 kg of substance A and 1.00 kg of substance B. After time t, the mass of residual substance A is equal to half of the residual substance B. Which of the options below gives a correct combination of half-life TB for B and time t? Assume that A does not produce B or vice versa during the conversions. Tbs? & t= s?
