La opción que mejor describe un vuelo que se está acercando a la velocidad del sonido es:<br /><br />A. Se crea más resistencia porque las moléculas de aire no se están moviendo fuera del camino del avión.<br /><br />Cuando un avión se acerca a la velocidad del sonido, experimenta un aumento significativo en la resistencia aerodinámica debido a la compresión de las ondas de choque y la acumulación de presión delante del avión. Esto hace que las moléculas de aire no puedan moverse rápidamente fuera del camino del avión, creando una mayor resistencia o drag.
