The irruption of mount Saint Helens in the 1980s resulted in the movement of volcanic ash across the northwestern United States. The movement of ash at 1.5 km above sea level is shown as a shaded path on the map the time is marked on the path indicate the length of the time the leading edge of the hash cloud talk to travel from mount Saint Helens to each location. Substitute values into the equation

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

it doesn't. it was imagined up in the middle ages.
