What is the relationship between half-life (radiometric dating) ad the absolute age of an object?

The radiometric dating is used to determine the absolute age of rocks. There are  unstable isotope elements that decay over time into stable elements. For those whose half-life is known it can be used to calculate the age based on the ration of the amount of the unstable elements and the number of stable atoms (that are products of the radioactivity) in the rocks.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
