The manufacturer of a 6 v dry-cell flashlight battery says that the battery will deliver 15 ma for 60 continuous hours. during that time the voltage will drop from 6 v to 4 v. assume the drop in voltage is linear with time. how much energy does the battery deliver in this 60 h interval? express your answer to three significant figures and include the appropriate units. ?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
