This means that we need a pipe that is 10.3 feet long in order for the pollutants to be reduced to 10% of their starting amount.

Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts.

Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.

Note that the purpose of this task is algebraic in nature -- closely related tasks exist which approach similar problems from numerical or graphical stances.

The standards do not prescribe that students use or know with log identities, which form the basis for the "take the logarithm of both sides" approach.

The two solutions provided differ slightly in their approach in this regard.

This is why it is such a big concern when a nuclear submarine sinks... (By the way, you are mostly Carbon-12, which is not radioactive.

Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.

After 5600 years, if we start with a gram, we end up with half a gram.
