Question
The rate at which a quantity of a radioactive substance decays is proportional to the quantity of the substance. The constant of proportionality is called the decay constant or decay rate (λ, like most physical constants, is conventionally represented by a positive number. That's why we call it a decay rate. If a quantity were increasing, we would use the words "growth rate" and also represent that by a positive number). Write the initial value problem that describes the amount N(t) of the radioactive substance remaining after time t, if the initial quantity N(0) is 2. dN dt N(0) What is the solution to the initial value problem? The half life of the substance is the time thalf at which exactly half of the substance remains. What is the half life in terms of λ? thalf
