Final answer:
The subject of this question is Physics, as it deals with the regulations governing the flight paths of commercial airliners.
Step-by-step explanation:
The subject of this question is Physics as it deals with the rules and regulations governing the flight paths of commercial airliners.
According to the Federal Aviation Administration, each airplane must maintain a specific distance from other planes and adhere to certain altitude restrictions. These restrictions are similar to the restrictions that electrons have on their locations in quantum mechanics.
By understanding the laws of physics, we can ensure safe and organized air traffic, just as the regulations govern the flight paths of commercial airliners.
