Karen and Randy are playing with a toy car and track. They set up the track on the floor, where the apparatus on the far left is used to launch the car forward by pressing down on the top portion. After the car is launched, it follows the track and continues upward, leaving the track. If the car has a mass of 211 g and it reaches a maximum vertical height of 2.67 m above the floor, what was the speed of the car while it was moving along the floor? Ignore the effects of friction and air resistance. m/s

their crystal patterns have been disrupted by stress

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
