Qee qhov kev qhuab qhia siv tus nqi-rau-ntau qhov piv (Q / m) hloov, uas yog qhov sib txawv ntawm qhov sib txawv ntawm qhov loj-rau-tus nqi. CODATA pom zoo tus nqi rau ib qho hluav taws xob yog Qm=−1.75882001076(53) × 1011 C⋅kg− 1.

tus qauv ntawm tus nqi tshwj xeeb yog dab tsi?

Tus nqi tshwj xeeb ntawm ib qho yog qhov piv ntawm nws cov nqi rau nws qhov hnyav, muab hauv coulombs ib kilogram (C kg–1). Txhawm rau xam cov nqi tshwj xeeb, koj tsuas yog faib tus nqi hauv C los ntawm qhov hnyav hauv kg.

Answer: 1.75882001076(53)×1011 C⋅kg−1.

SI unit ntawm tus nqi tshwj xeeb yog dab tsi?

The Coulomb (C) yog SI chav them nqi; Txawm li cas los xij, lwm cov units tuaj yeem siv tau, xws li qhia txog tus nqi ntawm cov nqi qis (e). Chav tsev SI ntawm lub cev muaj nuj nqis m/Q yog kilogram ib coulomb.

Qhov twg yog tus nqi tshwj xeeb tshaj plaws?

Ib qho hluav taws xob muaj qhov tshwj xeeb tshaj plaws ntawm cov khoom. Txhawm rau tuav nws koj yuav xav tau ntau dua rau tib qhov loj lossis lwm qhov qis dua thiab tus nqi tib yam.
