When a current I1=1.3 A passes through a wire of cross-sectional area A1=5 mm2the driftvelocity of the charge carriers is v1=2.7 ×10-5m/s. What is the drift velocity of the charges when acurrent I2=0.5 A passes through a wire, made of the same material of cross-sectional area A2=3mm2?

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?
