Step-by-step explanation:
In social studies, authority customs refer to the entity or person holding legitimate power in a specific realm based on long-standing customs. Power legitimacy, on the other hand, is the belief that those who have authority should have it. In the context of government, power and authority are granted by the people and are based on the consent of the people, known as popular sovereignty. The highest form of political power is legitimacy, as it reflects a government's ability to maintain trust and support from its citizens.
A constitution, in social studies, is a set of fundamental principles or established precedents according to which a state or other organization is governed. It outlines the structure, powers, and limitations of the government and protects the rights and freedoms of its citizens. Constitutions can exist at the national, state, or local level and provide a framework for a country's political system. The United States Constitution, for example, is the supreme law of the land and sets the foundation for the American government.
