The distance from the inner core to the surface of the earth is about 5,200 kilometers. the large amount of material surrounding the inner core places tremendous pressure on it. this pressure is one factor that causes the inner core to be in what state of matter?

does anyone know or what?

truck y has a greater velocity than truck x.

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.
