Expert Answer
Half life is calculated by- 
straight T subscript 1 divided by 2 end subscript space equals 10 space hours straight T subscript mean equals space 1.44 space straight T subscript 1 divided by 2 end subscript straight T subscript mean space space end subscript equals space 1.44 space straight T subscript 1 divided by 2 end subscript straight T subscript mean equals space 1.44 cross times 10 equals 14.4 space hr
