Carbon-14 has a half-life of 5,730 years. If scientists discover a mummified Cro-Magnon specimen, they will first want to determine its age. When examining a sample from the bone remains, the scientists discover the specimen is composed of 12.5% carbon-14 and 87.5% nitrogen-14. How old is this mummy? A. 5730 yrs old
B. 22920 yrs old
C. 11460 yrs old
D. 17190 yrs old

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear
