Final answer:
Power is distributed in the federal government through a system of federalism, where power is divided between the federal government and state governments. The federal government has enumerated powers, while state governments have reserved powers.
Step-by-step explanation:
In the government established by the U.S. Constitution, power is distributed through a system of federalism, where power is divided between the federal government and the state governments. The federal government has enumerated powers, which are explicitly listed in the Constitution, such as declaring war, imposing taxes, regulating commerce, and maintaining an army and navy. On the other hand, state governments have reserved powers, which are not delegated to the federal government and are instead retained by the states.
