A radioactive substance decays at a rate proportional to the amount present at ime t (in hours). Initially, Ao grams of the substance was present, and after 10 hours, the mount has decreased by 20% How long will it take the substance to decay to 40? hat is the half life of this substance? Hint: the half-life is the time required for half of the initial substance to decay)

A certain radioactive substance decays at a rate proportional to its remaining mass M. a. Express this rate of decay as a differential equation. b. When a living organism dies it ceases to replace the carbon isotope C-14, and 48. the C-14 that is present decays with a half-ife of about 5730 years. If archeologists discover a fossilized bone that has 30% of the C-14 of a live bone, approximately how old is it?

A radioactive material decays with a rate proportional to the amount present at any instant. a) Write and solve the differential equation. b) Use the solution of the differential equation to solve the following application problem. Carbon 14 (14C) is a radioactive isotope of the carbon element and has an approximate half-life of 5600 years. The fossil bones of an animal were analyzed and found to contain one-tenth of the radioactive 14C. Determine the approximate age of the bones found.

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 (B) 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 Unstable High Energy+ Atom Neutron Low Energy+...
