WebMar 10, 2016 · If it is 6,250 miles from the North Pole to the Equator and the radius of the Earth is 4,000 miles, then the curvature of the Earth should be on average about .64 miles, per mile, because 4,000 divided by 6,250 equals .64 or 3,379.2 feet of drop per mile. THAT'S INSANE! NOBODY SEES THAT! Web0. Showing a picture of the earth from space seems like the simplest way to prove that the earth is round, but first of all you would need to convince this tribesman that this photograph is taken from far up in the sky.

The equations for the relation between the differential distances and … WebUnless specified otherwise, the radius of the earth for the calculations below is: = 6,371.009 kilometers = 3,958.761 statute miles = 3,440.069 nautical miles. = Distance between the two points, as measured along the surface of the earth and in the same units as the value used for radius unless specified otherwise. Intuitively, the curvature describes for any part of a curve how much the curve direction changes over a small distance travelled (e.g. angle in rad/m), so it is a measure of the instantaneous rate of change of direction of a point that moves on the curve: the larger the curvature, the larger this rate of change. In other words, the curvature measures how fast the unit tangent vector to the curve rotates (f… how to start car with automatic starter
