Explain how symbols indicate that shows the a convergent boundary and not a divergent boundary

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

im guessing the west of station b

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
