Final answer:

Step-by-step explanation:
The tenet of airpower described in the question is unity of effort. Unity of effort is a concept in military strategy that emphasizes cooperation and coordination between different branches of the armed forces to achieve a common objective.
During World War I, airpower emerged as a new dimension of warfare. The ability to employ aircraft effectively required coordination between ground forces, navy, and air forces. By combining forces across multiple domains, such as land, sea, and air, the military could produce effects that exceeded the contributions of forces employed individually.
Unity of effort allows for synergy, where the combined capabilities of different forces can be coordinated to achieve greater impact and effectiveness. By utilizing diverse capabilities and expertise, a coordinated force can take advantage of different strengths and overcome individual limitations, resulting in a more comprehensive and powerful military operation.
