Half life problems and solutions

WebTo find the half-life of a function describing exponential decay, solve the following equation: [latex]\frac{1}{2}{A}_{0}={A}_{o}{e}^{kt}[/latex] We find that the half-life depends only on the constant k and not on the starting quantity [latex]{A}_{0}[/latex]. The formula is derived as … WebHalf-Life. We now turn to exponential decay.One of the common terms associated with exponential decay, as stated above, is half-life, the length of time it takes an exponentially decaying quantity to decrease to half its …
