Two free vortices of equal strength, but opposite direction of rotation, are superimposed with a uniform flow (v~ = uˆi). the first vortex, of clock-wise rotation, is located at (0,h) and the second is located at (0,-h). the stream function for a vortex of positive strength is given by

the plateau is likely to turn into a desert do to corrosion.

newton's first law of motion

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.
