Do not answer unless you actually now how to do
a 0.20-kg stone is thrown vertically upward with an initial velocity of 7.5 m/s from a starting point 1.2 m above the ground.
(a) what is the potential energy of the stone at its maximum height relative to the ground?
(b) what is the change in the potential energy of the stone between its launch point and its maximum height?

Which property of fossils allow scientists to determine the relative rock ages..

Which of the following are guidelines to follow for obtaining accurate observations

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.
