Textbook Question
Chapter 32, Problem 29PCE
Suppose we were to discover that the ratio of carbon-14 to carbon-12 in the atmosphere was significantly smaller 10,000 years ago than it is today. How would this affect the ages we have assigned to objects on the basis of carbon-14 dating? In particular, would the true age of an object be greater than or less than the age we had previously assigned to it? Explain.

Charan is at NASA analyzing Moon rocks. In one of the rocks from the lunar highlands, he discovered 37 % of the original uranium-238 remains, while remaining amount of uranium-238 had decayed into lead. The half life of uranium-238 is 4.5 × 109 years. Assume the only decay product is lead. How old is the lunar maria rock in billions of years (109 years)?
Xavier is at NASA analyzing Moon rocks. In one of the rocks from the lunar Maria, he discovered 80% of the original uranium-238 remains, while remaining amount of uranium-238 had decayed into lead. The half life of uranium-238 is 4.5 x 109 years. Assume the only decay product is lead. How old is the lunar Maria rock in billions of years (109 years) ?
