Q #1 Please show step by step to the solution Initially there are 6*10power 9 radioactive ofelement w (decayconstant 0.173/day) in a sample. As anucleus of w decays, it converts 2.67*10power -28 kg of its massto energy and releases the energy. Howmuch time (in days) isrequired for the samplwe to release a totalof 7.2*10 power -4j? (a) 0 (b) 0.000290 (c) 0.00571 (d) 0.0137 (e)0.00943 (a,b) 0.0290 (a,c) 0.0571 (a,d) 0.290 (a,e) 0.571 (b,c) 3.29
