Final answer:
Power is divided between the federal government and state governments under the concept of federalism. The federal government has authority over national issues, while state governments have powers that pertain to their own state.
Step-by-step explanation:
Under the concept of federalism, power is divided between the federal government and the state governments. The federal government has authority over issues that affect the entire country, such as foreign relations, national defense, and interstate commerce. On the other hand, state governments have powers that pertain to their own state, such as education, law enforcement, and transportation. This division of power allows for a balance between national and state interests, as outlined in the U.S. Constitution.
