1. A mummy was recently discovered. It now contains 68.3% of its original Carbon 14. About how old is the mummy? Assume that the half-life of Carbon 14 is 5730 years. 2. Element X has a half-life of 66 days. If we currently have a 23 ounce sample of Element X, how long will it be until only 9 ounces remain? ROUND YOUR ANSWER TO 2 DECIMAL PLACES. After about __________ days, only 9 ounces will remain 3. A body was found in the basement of the Underwater Basket Weaving Building at 12:00 noon today, where the temperature is a steady 65 degrees Fahrenheit. When found, the core temperature was 92 degrees Fahrenheit. Two hours later, at 2:00 PM, the core temperature had fallen to 88. Assuming that the body temperature was 98.6 at the time of death, use Newton’s law of cooling to find the time of death. ROUND TO 2 DECIMAL PLACES. The time of death was about __________ hours before the body was found.
