At a given instant there are25% undecayed radioactive nuclei in a sample. After10 s the number of undecayed nuclei reduces to 12.5%. Calculate(a) mean life of the nuclei,(b) the time in which the number of undecayed nuclei will further reduce to6.25% of the reduced number. πŸ“²PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
