10. Ўлчов воситалари мўлжалланишига қараб қандай тизимларига бўлинади?
II. Амалий топшириқ
Мисол:
СИ тизимининг асосий бирликлари орқали тезлик бирлигини қандай ифодалаш мумкин?
Мисолни ечилиши:
Қўйидаги тенгламадан фойдаланамиз:
а = V/t = S/t2.
бу ерда S – йўл (L деб белгилаб оламиз).
t – вақт (Т деб белгилаб оламиз).
Жавоб: демак, dim a = LT-2.
Мисол:
Х физик катталик миқдорининг ўлчами халқаро стандартга мувофиқ L, M, T, I бош ҳарфлар билан dimХ = LMT-3I-1 ўлчов формуласи шаклида ёзилади. СИ тизимининг асосий бирликлари орқали ушбу миқдор бирликларининг ифодасини ёзинг, унда ўлчанадиган номини ва физик катталигини кўрсатинг?
