Ron Torell, former University of Nevada Extension livestock specialist now retired, wrote a few years back that most cows pay for themselves by age six. âThus, the longer a cow stays in the herd, the more profitable she becomes.
Naturally, these hours, minutes, and seconds are shorter than the solar hours, minutes, and seconds you are familiar with. One solar day is 24 solar hours long, and one sidereal day is 24 sidereal hours long, but one sidereal day is 23 solar hours and 56 solar minutes long. This exercise was based on a help section of CyberSky. A shareware version of CyberSky is available from http://www.cybersky.com .
There are 86,400 seconds in one 24-hour day.86,400 because there are 24 hours in one day and each hour has 60 minutes and each minute has 60 seconds so 24 hours times 60 minutes equals 1440 times 60 seconds equals 86,400.However, a sidereal day (Earth's rotational period) is slightly shorter. The sidereal day is 86164.0916 seconds long.
