The activity of an old piece of wood is just 1/4 of the fresh piece of wood. If `t_(1//2)` of C-14 is 6000 years, the age of the piece of wood is

The activity of an old piece of wood is just one fourth of a fresh piece of wood. If half life period of ""^(14)C is about 6000 years, the age of old piece of wood is:

The activity of carbon-14 in a piece of ancient wood is only 12.5 % . If the half life period of carbon-14 is 5760 years, the age of the piece of wood will be

The amount of ._(6)^(14)C isotope in a piece of wood is found to one fourth (1/4) of that present in a fresh piece of wood. Calculate the age of the piece of wood (t_(12) "of "_(6)^(14)C=5770 "years") a) 7999 year b) 11543 year c) 16320 year d) 23080 year

The amount of C-14 in a piece of wood is found to be 1/6 of the amount present in a fresh piece of wood. What is the age of the wood ? (t_(1//2) for C-14 =5770 years)

A piece of wood floats on water.
