DESCRIPTION:What is the period of the Earth's rotation around its axis?As 
 a rule\, answer to this question is that that one turn around the axis of 
 the Earth requires\, approximately\, 24 hours and that this period is cold
  the mean solar day. Either\, more precisely\, some four minutes shorter s
 tellar day.In fact\, neither of these days stands for the Earth's full spi
 n period. Earth turns around its axis considerably more slowly. The only f
 rame of reference in which its intrinsic rotation is clearly defined\, whi
 le its orbital motions are excluded\, has to be the one related with the M
 oon. The full spin period of our planet is about 50 minutes longer lunar d
 ay – the time between one lunar zenith to the next. The term tidal day i
 s also in use in oceanography.- - - - - - - - - -Koliko je vremena potrebn
 o da se Zemlja jedanput obrne oko svoje ose?Odgovor na to pitanje je\, po 
 pravilu\, da njena puna rotacija traje\, približno\, 24 časa i da se taj
  period vremena zove srednji solarni dan. Uz to se obično dodaje da je ta
 čno vreme te rotacije nekih četiri minuta kraći stelarni dan.Ni jedan\,
  ni drugi odgovor\, međutim\, nisu ispravni. Zemlja se obrće oko svoje o
 se znatno sporije. Jedini koordinatni sistem u kojem je njena sopstvena ro
 tacija jasno definisana i u kojem su njena orbitalna kretanja isključena\
 , mora biti vezan za Mesec. Period punog spina naše planete je\, otprilik
 e 50 minuta duži lunarni dan\, koji se koristi u okeanografiji i meri od 
 jednog do drugog Mesečevog zenita.\n\nhttps://events.saifa.rs/event/42/
