Similar in exponential decay 10 grams of a radioactive materials are present after a certain time period it will decayed to 5 grams now from this point the further decaying process will depend upon these 5 grams present currently
examples of natural processes showing exponential growth or decay are<span>·<span> </span></span>Population growth<span>·<span> </span></span>Bacterial growth rate<span>·<span> </span></span>Viruses growth rate<span>·<span> </span></span>Radioactive decay<span>·<span> </span></span><span>Temperature decrease</span>
I think it is 3 but im not 100% sure
