An electric point charge of q1 = 7.85 nc is placed at the origin of the real axis. another point charge of q2 = 3.67 nc is placed at a position of p = 2.88 m on the real axis. at which position can a third point charge of q = -3.47 nc be placed so that the net electrostatic force on it is zero? let the sign of q2 be changed from positive to negative. at which position can the point charge q be placed now so that the net electrostatic force on it is zero?

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?
