1 Carbon-14 is an element that loses about 10% of its mass every millennium (i. e., 1000 years). A sample of Carbon-14 has 600 grams.
How much will the sample weigh after 8,000 years? (Round to the nearest gram)

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
