Q#1 Please show full working solution. Thesolutionpresented earlier for this problem wasn't clear sothat is why ire-sent it for more clearification. please helpme.Thank you Initially there are 6*10 power 9 radioactive ofelement w(decay constant 0.173/day or per day) in asample. As a nucleus of wdecays, it converts 2.67 *10power-28 kg of its mass to energy andreleases the energy. How much time(in days) is required for thesample to release a total of7.2*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
