When introduced into a region where an electric field is present, an electron with initial velocity V will eventually move:. a) along an electric field line, in the positive direction of the line
b) along an elecetric field line, in the negative direction of the line
c) to a point of decreased potential
d) to a point of increased potential
e) as described in both (b) and (d)

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?
