Latitude exact relationship of parallels and meridians with horizontal and vertical: both are complicated curves. On the sphere the normal passes through the centre and the latitude () is therefore equal to the angle subtended at the centre by the meridian arc from the equator to the point concerned. If the meridian distance is denoted by then where denotes the mean radius of the Earth. is equal to . No higher accuracy is appropriate for since higher-precision results necessitate an ellipsoid model. With this value for the meridian length of 1 degree of latitude on the sphere is (60.0 nautical miles).
What on Earth! habits and funeral rites of this "species." The film shows the earth from the view of the Martian flying machines which did not land but used cameras to film earth society. It then follows one average (what it believes to be) earthling and its civilization, by in effect showing a "day in the life" and how they live it. First, it shows one going through dinner with a precisely regulated feeding (vehicle refueling from a gas pump), then it must take its rest (pulling into an attached garage next to a house), because it will have a busy day the
