1) Suppose that while lying on a beach near the equator of afar-off planet watching the sun set over a calm ocean you start astopwatch just as the top of the sun disappears. You then standelevating your eyes by a height /H/ = 1.65 m and stop the watchwhen the top of the sun again disappears. If the elapsed time is/t/ = 11.6 s what is the radius /r/ of the planet to twosignificant figures? Notice that duration of a solar day at thefar-off planet is the same that is on Earth
