Answer:
When an aircraft is flying at high speeds, the airflow around the wings undergoes various changes. One of these changes is the formation of shock waves, which occur when the airflow reaches or exceeds the speed of sound (Mach 1). These shock waves are caused by the compression of air molecules and can have an impact on the aircraft's performance.
In the case of a swept wing aircraft, the wings are designed with a backward angle (sweep) relative to the fuselage. This sweep helps delay the onset of shock waves and reduces the drag caused by airflow reaching Mach 1. However, at some point along the wing's leading edge, the airflow will reach Mach 1, forming a shock wave.
The exact location where airflow first reaches Mach 1 on a swept wing aircraft can vary depending on factors such as the wing's sweep angle, the aircraft's speed, and its specific design. Therefore, it is important to consider these factors when determining where the airflow first reaches Mach 1 on a specific aircraft.

Answer:
The correct answer is: over urbanization
Explanation:
Overurbanized countries are characterized by the inability to maintain their populations in terms of employment and resources. The term is intentionally comparative and has been used to differentiate between developed and developing countries. Several causes have suggested, but the most common is rural and urban-push-pull factors, in addition to population growth.
This phenomenon has two aspects: the first is the process by which the population increases radically in the cities - urbanization process - compared to the rural population; the second is produced by the preeminence of cities or metropolises - generally considered primate cities that absorb the population of a whole country or territory since they constitute attractive economic centers in front of a rural periphery, deindustrialized and generally impoverished and aged.
