Question

which information can be determined using half - life?
age of material
type of particle released
percentage of rock that has aged

Explanation:

Half - life is used in radioactive dating to find the age of a material. It is based on the decay of radioactive isotopes. The type of particle released is related to the type of radioactive decay and not directly determined by half - life. While the percentage of a rock that has aged can be related to half - life calculations, the most fundamental use is to find the age of the material.

Answer:

age of material
