Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
If radioactive decay rates were not constant, the passage of time inferred from radiometric dating would be inaccurate. Changes in decay rates would affect the ratio of parent to daughter isotopes used in dating, leading to flawed age calculations. The fundamental assumption of radiometric dating is that decay rates remain constant over time.
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
Radiocarbon dating measures the decay of carbon-14 to determine the age of organic materials up to about 50,000 years old, while thermoluminescence dating measures the trapped electrons in soil or pottery to date inorganic materials up to hundreds of thousands of years old. Radiocarbon dating is limited by the availability of organic material, while thermoluminescence dating is limited by the environment in which the artifacts were buried.
Yes, the Philippines is an archipelago because it is composed of about 7,641 islands. An archipelago is a group of islands clustered together, which is why the Philippines fits this definition.
Someone who studies history is called a historian. Historians research, analyze, and interpret historical events, people, and societies to understand and explain the past.
A person who studies events and the past is called a historian. Historians analyze and interpret historical evidence to understand and explain past events, societies, and cultures.

To fully explain radioactive decay you need quantum mechanics.
To be accurate, a theory must continue to explain what
To be accurate, a theory must continue to explain what

In contrast, for an ellipse it is the ''sum'' of these distances that is a constant
You need to explain what transformation you refer to. The transformation of the empire in the west relation to what? You also need to explain why it would need to be accurate/inaccurate.
The amount of the remaining radioactive isotopes it contains.
227Ac----- alpha decay---- 223Fr
yes
It is a 2 dimensional map
because your going downhill
