Edward recorded the height of an oak tree in his yard and graphed the results. He did not measure the height in 2006 or 2009

a) Using interpolation, what was the approximate height of the tree in 2006? (

b) Interpolate to find the approximate height in 2009.

c) Using extrapolation, what would you predict the height to be in 2011? (1 point)

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.
