An infinite line of charge (positive linear charge density o) along the z-axis is surrounded by a hollow, infinitely long charged cylindrical shell (radius r, negative surface charge distribution o(s = r) = -ao) centered on the z-axis a. use coulomb's law to write an integral expression for the electric field at an arbitrary point (s, 4, z) b. use gauss's law to find expressions for the electric field in all regions of space graph the x-component of the electric field as a function of position along the x- axis c.

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?
