Ex: Exponential Model - Determine Age Using Carbon-14 Given Half Life

This video explains how to use half like to determine an exponential decay rate and then determine how old an artifact is given a percent of carbon-14 remaining.

I had a similar problem and struggled with it for too long. Thanks for posting this! It allowed me to get some hints, do my own work then check back here to confirm my thinking was correct. Big Thanks!

Got a problem similar to this on my homework and could not figure it out! Thanks!!!

[lolwhy]

U r a god rn ive been on a similar problem for and hr trying to put numbers together

[cayladelorenzo]

Thank you so much for this tutorial! It helped me solve my problem. You are fantastic at explaining it to!

[sarrakitty]

This exact problem in my textbook, I mean the exact same problem verbatim, was one I got assigned for homework. LOL, this sure made things easy for that assignment!

Hi, may I know how do they get the 5, 730 years? Thanks

Can you answer this question pls, really tough I think!!!
The rate of decay of a radioactive source falls from 3000 counts per minute to 2000 counts per minute 5 minutes later. What is the half-life of the radioactive source?

[EndTimeMagi]

So, the carbon 14 half life of 5730 years means it can't be used to date the age of dinosaur fossils older than twice that of the half life, or much less.

thank you good sir, you just saved me 😌✨✨

[hassenalnaib]

can u please explain how did you get 5700 years

[wilddog]

... Where did the 1 gram and the 1/2 gram come from?

[maxcomplexstudio]

I solved it without calculus but with logarithm, ans. 4223 yrs.🎉🎉

Allow me to State some massive problems with radiocarbon dating. The decay rates are affected by solar flares. All kinds of radiations can actually accelerate the aging process of radiocarbons and since we cannot currently quantify all the solar flares and radiation that is affecting each element we cannot presume to date things using this method. dating by layers of Earth is also a mistake given that we have seen meteorites strike the Earth causing megatons of Earth to be ejected into the lower atmosphere only to drop down in hundreds of layers over the period of days. We've seen volcanoes erupt that caused multiple layers in hours. Science is still a baby. It needs to grow up still.
