How to have scrolling vertically as well as horizontally inside fragment of fragment activity?

What would you like to ask?A pottery fragment is discovered in an archeological excavation site. Measurements?

  • Answer:

    First find the number of half lives that have elapsed. It will be slightly more than one, since there is slightly less than half left. .4 = 2^ [-HL] where HL is the number of half lives elapsed. Since that is not solvable, take the log of each side Log[.4] = - HL log[2] HL = 1.32 So it has been 1.32 x 5730 = 7575 years Now, it strikes me as very unlikely that anyone was able to separate C14 around 5500 BC....
