Solving for disintegration constant

disintegration constant

Inputs:

time (t) 
number of nuclei after time period (N) 
initial number of nuclei(N0) 

Conversions:

time (t) = 0    = 0  second
number of nuclei after time period (N) = 0    = 0  
initial number of nuclei(N0) = 0    = 0  

Solution:

disintegration constant (Kb)  =  HAS NOT BEEN CALCULATED
