Please answer 2 3 and 4. thanks .
1. In this activity, we will be exploring the relationship between the amount of a radioactive substance and the rate of decay. There are many forms of radioactive decay. For this activity we will be using beta (8) decay, when a neutron decays into an electron and proton, and gamma (7) decay, when an atom emits energy through a gamma photon. B- Decay y Decay High Energy+ Unstable Atom Neutron Low Energy+...

Question 75 5 pts Determine the age of the zircon mineral grain from a granite in the Sierra Nevada using the 14C to 14N method. The mineral has 5678814C atoms and 87655 14N atoms. The half life (T1/2) of this system is 5730 years. What is the age? Use the curve equation T = -1.4431n(f) 1. Determine Pi, initial parent amount (add Parent Daughter) 2.f P/Pi 3. Use the curve equation to solve for T (number of half lives elapsed)...
