I am lost on how to find this. I was multiplying the resistance by the current? I am assuming that is not the formula

I wrote down the equations and did them one by one on a scrap piece of paper. And thank you for the help :)

Well there has to be a way to figure it out. It is the text and is required to be answered, so there has to be an answer. I can't just put can't find

I was assuming because R3 and R4 are parallel that the values would be the same.

No there is no value for R3

I made a chart and this is my attempt. I am not sure that I am doing the calculations right thou

Thank you so much for helping me. I understand now!

So the iceman has gone through approx 1 full stage of half life carbon cycle. So he was alive approx 6000 years before 1991? and then using that thinking if he had only 25 % percent carbon 14 than he would have lived 2 half life cycles which would mean he was alive 12000 years? am i getting it now?

what about if I did it this way. If you lose 50% every 6000 years that means you would lose 1% every 120 years. So if he lost 48% as there is 52% remaining does that mean I can take 48 %* 120 years which then means he died 5760 years ago in 1991 when he was found?

So he died approx 3000 years before 1991? Thats it? I was thinking i needed more a technical answer

.5

48/6000 ? he was alive 2880 years before 1991?

48%

It means that you can use this method of radiocarbon dating to approx time an organism died. So every 6000 years half of the carbon is gone.

I had tried to come up with a formula that would help me figure it out, but I honestly am not sure where to begin. In my book it states that the carbon-14 half life is 6000 years. ( I have read somewhere else that it is 5730 but I am using 6000 as that is what was supplied) so the only thing i...
