Kat is creating a model to show how plate movements are linked to the formation of new rocks, and she is trying to place the steps in the correct order. which step comes first? the tectonic plates move apart from one another lava flows onto earth's surface magma forms beneath the plates and rises up through the cracks lava cools and hardens to form igneous rock

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?
