a nonmechanical water meter could utilize the hall effect by applying a magnetic field across a metal pipe and measuring the hall voltage produced. what is the average fluid velocity in a 3.00-cm-diameter pipe, if a 0.500-t field across it creates a 60.0-mv hall voltage? (enter the answer in m/s and should be in three significant figures)
