Suppose that, while lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears.You then stand, elevating your eyes by a height H = 1.70 metres, and stop the watchwhen the top of the Sun again disappears, If the elapsed time is t=11.1 s, what is the radius r of earth?
