  7. Pretvarjanje enot 1000 m = 1·103 m = 1 km = 1 kilometer 0,23 m = 2,3·10-1 m = 2,3 dm = 2,3 decimetra 10a10b = 10a+b 10a/10b = 10a-b 10-a = 1/10a 10a = 1/10-a Fizika OTM, 2009/2010

  8. S  r Kot s = pr/2  = p/2 s = 2pr  = 2p s = pr  = p r r r Fizika OTM, 2009/2010

  9. Napake pri merjenju vrednost merjene količine xdoločamo iz izmerkov xi, i = 1,2,… N efektivna napaka relativna napaka povprečna vrednost dolžina je med 7,21 m in 7,25 m; povprečna vrednost je 7,23 m; efektivna napaka je 0,02 m; relativna napaka je 0,003 = 0,3 % Fizika OTM, 2009/2010
