Los materiales de aluminio para construcción tienen un recubrimiento duro, protector, transparente de óxido de aluminio, Al2O3, que se forma al reaccionar con O2. El ácido sulfúrico, H2SO4, de la lluvia ácida disuelve este recubrimiento protector y forma sulfato de aluminio, Al2(SO4)3, y agua. ¿Cuál sería la ecuación para esto?

Natural forces that can alter ecosystems include seasons and climate changes. t or f

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

If state law mandates that elevators cannot accelerate more than 2.40 m/s2 or travel faster than 14.8 m/s , what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor? ?
