Question

C-14 is a beta emitter, and is used to estimate the age of archaeological artifacts. It is one of three naturally occurring isotopes of carbon.
What is the natural abundance of C-14?

Answer 1

Answer:

Point B is the midpoint of Line segment A C . Horizontal line with points A, B, and C. A vertical line extends from point B through point D to create two right angles. Which statements about the figure must be true? Select three options. AngleDBC is bisected by ray BD. AngleABC is bisected by ray BD. BC = One-halfAC Line segment D B is-congruent-to Line segment B C 2mAngleDBC = mAngleABC
