Inez is making a model of a sugar crystal. She wants her model to show how the sugar molecules move in the crystal. She is using plastic foams balls to represent the sugar molecules. How should she put the plastic foam balls together to make her model

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

found in the nucleus

has mass of one amu

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.
