Nyob rau hauv kev txiav txim qhia sign ib khoom nqi , koj xav tau lwm tus khoom nrog a paub zoo los tsis zoo nqi . Yog koj rub ib daim iav nrog lo lo ntxhuav, nws yuav muaj qhov zoo nqi (los ntawm convention). Yog koj rub ib daim ntawm amber nrog pluab, nws yuav muaj qhov tsis zoo nqi (tseem los ntawm kev sib tham). Siv txhua yam koj muaj ke.
Ib yam li ntawd, koj yuav nrhiav tau tus nqi ntawm ib yam khoom li cas?
Rau txiav txim tus nqi on ib khoom , txiav txim tus naj npawb ntawm ntau tshaj protons lossis tshaj electrons. Multiply tus tshaj los ntawm nqi ntawm ib tug electron los yog lub nqi proton - 1.6 x 10-19 C. Thaum kawg, kho qhov kos npe ntawm tus khoom mus + or -.
Tsis tas li ntawd, tib neeg lub cev puas zoo lossis tsis zoo? Hluav taws xob muaj nyob txhua qhov chaw, txawm nyob hauv tib neeg lub cev . Peb cov hlwb tau tshwj xeeb los ua cov khoom siv hluav taws xob. Resting cells yog tsis zoo nqi nyob rau sab hauv, thaum sab nraud ib puag ncig yog ntau dua raug nqi zoo . Qhov no yog vim qhov tsis sib xws me ntsis ntawm zoo thiab tsis zoo ions sab hauv thiab sab nraud ntawm tes.
Tsis tas li ntawd, yuav ua li cas ib qho khoom raug them tsis zoo?
Ib khoom raug them Thaum nws yog atoms poob los yog nce electron los ua ib qho ion. Piv txwv li: Hydrogen atom muaj ib qho zoo proton thiab ib qho tsis zoo hluav taws xob. Cov plaub hau zoo raug them vim nws poob electrons thiab tus pas nrig yog tsis zoo nqi vim nws tau txais electrons.
Coulomb txoj cai lij choj yog dab tsi?
Coulomb txoj cai formula Coulomb txoj cai xam qhov hluav taws xob quab yuam F nyob rau hauv newtons (N) ntawm ob tug nqi hluav taws xob q1 thiab q2 hauv coulombs ua (C) nrog qhov deb ntawm r hauv meters (m): F yog lub zog ntawm q1 thiab q2 ntsuas hauv Newton (N). k yog Coulomb cov Luas = 8,988 × 109 N⋅m2/C2.

Yuav ua li cas koj thiaj paub tias ib yam dab tsi muaj nuj nqi los yog tsis?
LUS TEB: Cov lus teb piv txwv: Koj tuaj yeem txiav txim siab seb txhua lub ntsiab lus ntawm lub npe yog ua ke nrog ib qho ntawm qhov ntau. Piv txwv li, yog tias muab ib daim duab, koj tuaj yeem siv qhov ntsuas kab ntsug; Yog hais tias ib txoj kab ntsug hla cov duab ntau dua ib zaug, ces qhov kev sib raug zoo uas cov duab sawv cev tsis yog ib qho haujlwm
Yuav ua li cas koj thiaj paub yog tias tus nqi sib npaug tsis muaj kev daws teeb meem?
Tus nqi tiag tiag ntawm tus lej yog nws qhov kev ncua deb ntawm xoom. Tus lej ntawd yuav yog qhov zoo, vim koj tsis tuaj yeem ua tsis zoo ob txhais taw deb ntawm ib yam dab tsi. Yog li txhua tus nqi sib npaug sib npaug sib npaug rau tus lej tsis zoo yog tsis muaj kev daws teeb meem, txawm tias tus lej ntawd yog dab tsi
Yuav ua li cas koj thiaj paub tias ib yam dab tsi yog ib yam khoom dawb huv los yog sib tov?
1. Cov tshuaj dawb huv tsis tuaj yeem muab cais ua lwm yam teeb meem, thaum sib xyaw yog sib xyaw ntawm ob lossis ntau dua cov khoom ntshiab. 2. Cov khoom ntshiab muaj lub cev tsis tu ncua thiab tshuaj lom neeg, thaum cov khoom sib xyaw muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (piv txwv li, qhov kub thiab txias)
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
