One end of a copper rod 30 cm long is held at 200C, and the other end is held at 93C. The heat transfer coefficient in between is 17 W/m squared K (including both convection and radiation). if T infinity = 38C and the diameter of the rod is 1.25 cm, what is the net heat removed by the air around the rod?

the answer is 3.1 his answer is wrong mines is right

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.
