The half-life of a radioactive element which has only 1 of its original mass leftafter elapsed of 60 days is:A. 30 days ⃝ B. 20 days ⃝C. 15 days ⃝ D. 12 days
Question
Solution 1
The half-life of a radioactive element is the time it takes for half of the element to decay.
In this case, we know that only 1/4 of the original mass is left after 60 days. This means that the element has gone through two half-lives.
To find the length of one half-life, we simply divide the tot Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
