9 hours ago 17Calculus Precalculus - Half-Life. Half-life is closely related to exponential decay. Half-life is the time it takes for half the substance to decay and, therefore, is related only to exponential decay, not growth. The idea is to take the equation , set the left side to and solve for . Notice that you don't have to know the initial amount

What is the half life formula?  Socratic
Preview

Just Now The general equation with half life=. N (t) = N (0) ⋅ 0.5 t T. In which N (0) is the number of atoms you start with, and N (t) the number of atoms left after a certain time t for a nuclide with a half life of T. You can replace the N with the activity (Becquerel) or a dose rate of a substance, as long as you use the same units for N (t) and N

7 hours ago Half life equation. Every decaying substance has its own half life, because half life is the amount of time required for exactly half of our original substance to decay, leaving exactly half of what we started with. Because every substance decays at a different rate, each substance will have a different half life.
