During moderate physical activity a m = 70 kg man may consume 260 Cal/hr. Of this amount, at least Q = 208Cal is converted to heat. Find increase in body temperature AT if the heat would remain within the body. Specific heat of the average human body is c=3.5*10^ 3 J/kg^ .0 C

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.
