An archaeologist digs up a piece of wood believed to be an ax handle from a dig. The wood is from an ash tree. The beta emission from the old piece of wood is 4 beta/min. A similar piece of wood that is freshly cut registers beta emission at 16 beta/min. The half-life of carbon-14 is 5,370 yrs. How old is the piece of wood from the dig? Is it 5370yrs./2? Thanks.
