a uniform solid cube 0.5 m on each side and with a mass of 100 kg floats in water. what percent of the cube’s volume is above the surface of the water?

compass can be used day and night, cloudy or sunny

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.
