UCLEAR REACTIONS (10 PTS) 1. In an alternate universe where it is safe to consume radioactive materials in hopes of gaining a superpower, Josh was challenged to swallow a radioactive sago that was radio labelled with an isotope of a certain element emitting protons. The half-life of the isotope is 68 minutes. If he swallowed the radioactive sago at 10:10 P.M. on Monday, at what time and day would it reach 17% of its original amount?
