Show that from heisenberg's equation of motion in ihe(7.0)= we can obtain the schrödinger equation (this demonstrates the connection between the second quantization and elementary quantum mechanics)

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?

Arrange the images in order to show how lake-effect snow occurs.
