QUESTION #1

Initially there are 6*10 power 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*10 power -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
