decay?​

Answer 1

Explanation:

HI BUDDY GOOD MORNING

Tet initial amount =100N0

Amount decomposed = 99.99%

N = amount left =100−99.99

               

                           =0.01N0

 

   ∴λ=t2.303logNN0

      1.530.693=t2.303log0.01100

      t=20.34 sec

HOPE FOR YOUR BETTER DAY AND BEST DAY TODAY
