A skyrocket explodes 78 m above the ground. Three observers are spaced 70 m apart, with observer A directly under the point of the explosion. A B C 78 m 70 m 70 m Find the ratio of the sound intensity heard by observer A to that heard by observer B. For practical purposes, you may treat each observer as a point on the ground.

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.
