A sample of spruce wood taken from Two Creeks forest bed near Milwaukee, Wisconsin, is believed to date from the time of one of the last advances of the continental ice sheet into the United States. The ratio of 14C to 12C in the sample was found to be 0.2446 of the atmospheric value of this ratio. What is the daughter-to-parent ratio for the decay process in the sample? What is the estimated age of the spruce wood sample? Show calculations that support your answer.

A wooden artifact is found in an ancient tomb. Its carbon-14 (14/6C) activity is measured to be 60.0% of that in a fresh sample of wood from the same region. Assuming the same amount of 14C was initially present in the artifact as is now contained in the fresh sample, determine the age of the artifact.

= U is for Uranium. Natural uranium consists of 235U (percent abundance P₁ = 0.7300%, A₁ = 3.12 x 10-¹7 [s-¹]) and 233U (percent abundance P₂ = 99.27%, 2₂ = 4.92 × 10-¹8 [s-¹]). Consider the time when Earth was formed 4.5 billion years ago. Setup the time dependence of percent abundance of the two uranium isotopes. Use №₁ and N₂ as current particle count of the isotopes (use №₁,0 and N₂,0 for the initial particle count back when Earth was formed) Then, Compute for the initial percent abundance of each uranium isotopes when the Earth was formed.
