What type of reaction occurs initially with sodium azide when airbags initially deploy.
Luden [163]

The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.

1. Girona y Castellón están separadas 360 km. Un tren sale de Girona hacia Castellón con
Vlad [161]

Answer:

Ambos trenes tardarán 2 horas y 24 minutos en cruzarse.

Explanation:

Dado que el tren que sale de Girona lo hace una hora antes que el que sale de Castellón, y que circula a 108 km/h, al momento en que el tren que parte de Castellón inicia su recorrido la distancia entre ambos trenes, que en principio es de 360 km, se ha reducido a 252 km (360 - 108).

Así, luego de la primer hora de recorrido, ambos trenes se separan por 252 km. A la segunda hora, el tren de Girona ha recorrido otros 108 km, mientras el tren de Castellón ha recorrido 72 km, es decir, en total han acortado otros 180 km, con lo cual la distancia entre ambos ahora es de 72 km (252 - 180).

Ahora, para la última parte del recorrido, se debe dividir el horario. Así, el tren de Girona recorre 108 km en una hora, con lo cual, en 20 minutos, puede recorrer 36 km. A su vez, el tren de Castellón puede recorrer en el mismo tiempo 24 km, con lo cual, tras 2 horas y 20 minutos, la distancia entre ambos es de 12 km (72 - 60).

Para los últimos 12 km, debe dividirse el horario por un número menor. Así, en 4 minutos (60 / 15 = 4), el tren de Girona recorre 7.2 km (108 / 15 = 7.2), mientras que el tren de Castellón recorre 4.8 km (72 / 15 = 4.8). Así, dado que 7.2 + 4.8 es igual a 12, es decir, los km que faltaban para que ambos trenes se cruzaran, el tiempo en el cual ambos trenes tardarán en cruzarse es de 2:24 horas.
