Arrange the examples in order, starting with the object that has the least amount of energy. In each case, assume there’s no friction. Use g = 9.8 m/s2, PE = m × g × h, and . a book with a mass of
0.75 kilograms resting
on a shelf at a height
of 1.5 meters
a brick with a mass of
2.5 kilograms falling
with a velocity of
10 meters/second
when it’s 4 meters
above ground
a ball with a mass of
0.25 kilograms rolling
on flat ground with a
velocity of 10 meters/
second
a stone with a mass of
0.7 kilograms being
held still at a height
of 7 meters

What is the scientific definition of energy that relates to work

Give an example in which the electrical energy changes to light energy

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.
