Why is it important to hold the plunger in position for 15 seconds prior to measuring the pressure? (hint: consider what can happen if you rapidly and significantly change the gas pressure of an ideal gas. is it possible that other variables in the ideal gas law might change to compensate for the change in pressure? ) (2-5 sentences)

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.
