You are on a seashore in the tropics, watching sunset. If the bending of light in the atmosphere is neglected, and the visual size of the suns disk is half a degree in diameter, how much time (approximately) passes from the moment the disk just touches the horizon to when the disk disappears completely? Is sunrise any faster in the tropics--or actually slower--or else, latitude really makes no difference? Explain.
