Homework duo Feb 7', 2023 09:00 CST Backseattering Detective Part I 0,-"I point {graded} Two metal sheets, one made of an isotope of Sc with a nuclear radius of 3.54 n and one made of an isotope of In with a nuclear radius of 4.61 fm, were left unlabeled. Both sheets look identically thin and have an area of 1.50 x 10 2 1112. You have been tasked to use a backscattering experiment to differentiate between the two sheets. You decided to bombard each sheet with 5.00 x 10in alpha particles. Assuming that there are 5.00 X 1021 atoms in each sheet, how many backseattered alpha particles would you observe from the Sc metal sheet? 1.0t10"1\"l particles 3: 1.0-1011 You have 2 errors to correct: Your answer is outside the acceptable bounds. You may have made a calculation or rounding error. Also, your answer does not have the correct number of significant digits. You have used 2 of 'IO attempts 53"" Backseattering Detective Part II \"I point possible {graded} How many backscattered alpha particles would you observe from the In metal sheet? particles
