To solve the problem of finding the ratio of the nuclear radii of two nuclei with mass numbers in the ratio 8:125, we can follow these steps:1. Identify the Mass Numbers: Let the mass numbers of the two nuclei be \( A1 \) an
What is the fraction of 8%?Explanation:Percentage means per 100, so to change a percent to a fraction, we write the percent value over 100, in this case, 8/100. Then, we reduce the fraction, if possible, by dividing by a common factor. Both 8 and 100 are divisible by 4, so we...
