When an organism dies, the ratio of carbon-12 to carbon-14 in its body is the same as in every other living thing. however, the amount of carbon-14 is reduced by half every 5,700 years, while the amount of carbon-12 remains constant. if 25% of the carbon-14 present at the time of the organism’s death remains in its fossil, approximately how old is the fossil?

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
