Which of the following is an accurate statement? a. ac generators produce current that is pulsating, but always remains positive. b. step-up voltage transformers have a lower number of turns in the primary than in the secondary winding. c. dc generators produce current with a voltage that changes from positive to negative. d. step-down voltage transformers have a different number of turns in the primary than in the secondary winding, so they change the incoming voltage to a higher voltage.

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
