PLEASE PROVIDE STEP BY STEP WORKING SOLUTION TO THIS PROBLEM
Q#1
Initially, there are 6*10power 9 radioactive of element 'w' (decayconstant 0.173/day) in a sample. As a nucleus of 'w' decays, itconverts 2.67*10 power -28 kg of its mass to energy and releasesthe energy. how much time (in days) is required for sample torelease a total of 7.2*10power -4 j?
(a) 0, (b) 0.000290, (c) 0.00571, (d) 0.00943 ,(e) 0.0137, (a,b)0.0290,
(a,c) 0.0571, (a,d) 0.290, (a,e) 0.571, (b,c) 3.29
