a student On A Tower 14 and hydrops a stone once again later he throws a second stone after the first .they both hit the ground at the same time .with what speed did he throws the second stone.

magnityde and direction

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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.
