An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 163 g (HINT: Assume all the carbon is ¹²C and determine the number of atoms) and careful measurements show that the remaining ¹⁴C has a current decay rate of 21 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of ¹⁴C to ¹²C when the animal died was 1.3×10^-12 & the half-life of ¹⁴C is 5730 y.
age of bone =

A geologist finds an old rock and wants to determine its age using rubidium-strontium dating. This is possible because ⁸⁷Rb, which has a half-life of 4.75×10¹⁰ y, undergoes β ⁻ decay and becomes ⁸⁷Sr. The geologist determines that the ratio of ⁸⁷Sr to ⁸⁷Rb is 0.289. Assuming there was no ⁸⁷Sr in the rock when it was formed, determine the age of the rock.
age of rock =

A penny, which has a mass 2.5 grams and is made of zinc, is released from rest just beneath the surface of some 80 proof vodka. (80 proof means 40% ethyl alcohol and 60% water, by volume). If the height of the vodka in the bottle is 25cm, how long will it take for the penny to reach the bottom? (Ignore drag and other frictional effects. Assume the only effect of the fluid is buoyancy.)
