which information can be determined using half - life?\no age of material\no type of particle released\no…

Brief Explanations:

Half - life is the time required for half of the radioactive atoms in a sample to decay. Using the concept of half - life and decay equations, we can calculate the number of radioactive particles left after a certain time. While half - life can help estimate the age of a material in some cases (radiometric dating), it is not the most direct information it determines. The type of particle released is related to the type of radioactive decay (alpha, beta, gamma) and not directly to half - life. The percentage of rock that has aged is also related to age calculations which are more complex than just half - life alone.

Answer:

D. number of radioactive particles left
