The idea that states are unitary actors acting under anarchy and the structure of the system shapes their behavior is associated with which theory?

Neorealism

Explanation:

Neorealism is a theory of international relations that emphasizes that power is the most important tool.

It further argues that in neorealism or structural realism, the anarchic ordering principle of the international structure is decentralized, meaning there is no formal central authority; every sovereign state is formally equal in this system. These states act according to the logic of egoism, meaning states seek their own interest and will not subordinate their interest to the interests of other states.

explanation:

the masses of the objects and the distance between them

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
