Radiometric dating is the workhorse of absolute dating. if you had a sample with a radioactive component with a half-life of 5000 years and an initial concentration of one part per million, how much would be present after 5000 years? after 10,000 years? after 50,000 years? when does the radioactive material completely disappear?

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
