Consider a line of thunderstorms 30 miles wide and suppose (for simplicity) that the rainfall rate everywhere within this band of thunderstorms is 1.5 inches per hour. assume that the line of thunderstorms is oriented in a north-south direction and that it moves due east. how much rain will fall at a location over which the storms pass if the storms move at 30 mph?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
