Homework: Prueba extempornea Encue ntro Question 16, '3.2.25-26 Hw Score: 71.33%, 14 27 of 20 points lntermedio Part 5 m 5 3 Points: 0.6 on Assume that. the rate oi decay of a radioactive substance is proportional to the amount of the substance present. The half-life of a radioactive substance is the time ittakes for one-half of the substance to disintegrate Carbon dating is oen used to determine the age of a Iossii For example, a humanoid skull was found in a cave in South Africa along with the remains ofa campre. Archaeologists believe the age of the skull to be the same age as the campre. It. is determined that only 2% of the original amount oi carboneid remains in the burnt wood of the campre. Complete parts [a] through (e) below. (Round to the nearest whole number as needed.) - [b] Estimate the age of the skull itthe halfelite of carboneill is about 5600 years The skull is about 31606 years old. (Round to the nearest whole number as needed.) [c] Compare the answers to parts (a) and (b). Choose the coned answer below i The answer to part b) is less than the answer to part (a). Decreasing the half-tile decreases the age of the skull. The change in the age of the skull here is much less than the change in the half-life. . The answer to part b) is greater than the answer to part (a) Decreasing the half-life increases the age ofthe skull. The change in the age of the skull here is much greater than the change in the half-lite ( l The answer to part (b) is less than the answer to part [a]. Decreasing the half-tile decreases the age of the skull. The change in the age of the skull here is much greaterthan the change in the half-life. l l . The answer to part b) is greater than the answer to part (a) Decreasing the half-life increases the age ofthe skull. The change in the age of the skull here is much less than the change in the half-life [d] Estimate the age of the skull itthe half-life of carbon-14 is about 5T0!) years and 3% of the original amount of carbon-14 remains in the burnt wood ofthe campre The skull is about 28336 years old. (Round to the nearest whole number as needed.) [9] Compare the results of the previous parLs. Choose the coned answer below 0 A. The answer to part (d) is greater than the answer to part (a) Increasing the percent remaining by one percent greatly increases the age of the skull. O B. The answer to part (d) is less than the answer to part (a). Increasing the percent remaining by one percent decreases the age of the skull by a minimal 6) C. The answer to part (d) is greater than the answer to part (a) Increasing the percent remaining by one percent increases the age of the skull by a minimal ( C) D The answer to part d) is less than the answer to part (a). Increasing the percent remaining by one percent greatly decreases the age of the skull
