It is estimated that light takes 10,000 years to travel the full distance across our galaxy. if light travels at 3.0 x 10^8m in 1 second then what is the distance across the milky way? give your answer in standard form

If a simple machine reduces the strength of a force, what must be increased?

Place me with this question is my last question

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.
