Question
Half of a substance is 20 minutes, then the time between 33% decay and 67% decay will be
Options
A.20 minute
B.40minute
C.50 minute
D.10 minute
Solution
When the body is already 33% decayed to be decayed to a a further 33%, it will require a period equal to its half life. So achieve level of decay from 33% to 67% it takes time equal to half life or 20 minutes.
