p = principle
r = rate
t = time
A half-life is the time it takes for half of the substance to decay, becoming something else. You can find a list of half-lives in the Wikipedia article "List_of_isotopes_by_half-life".
The half-life directly affects how quickly something decays. It is the amount of time for a substance to lose half of its material, so the lower the half-life time, the faster something decays.
"In learning and going through challenges rather than living."
A Half-Life is half the time it takes for a radioactive element or a drug to lose its How_do_you_use_half_life_in_a_sentenceor change into something else.
i think you divide the whole number of lives by halves. Im not sure were gonna begin that next week.
A half life means the time required for something to fall to half its initial value. The original term was used by Ernest Rutherford's discovery of the principle in 1907 as "half life period," but was shortened to "half life," in the 1950's.
there are alot of ways to find hacks for half life i used to have a it cheat book but i lost,to find cheats use the internet
The half-life of 238U is 4,468x109 years.
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
All elements have a certain "life-span," until they degrade into either sub-atomic particles, or react with something else. Half-Life is literally the half-point in their life-span.
