Kuj hu ua permittivity ntawm qhov chaw dawb, nws yog ib qho zoo tagnrho lub cev tas li uas sawv cev rau qhov tseeb dielectric permittivity ntawm lub tshuab nqus tsev. Hauv lwm lo lus, epsilon tsis quantifies lub peev xwm ntawm lub tshuab nqus tsev tso cai rau hluav taws xob teb cov kab khiav los ntawm. Nws yog kwv yees li 8.854 × 10^-12 farads ib 'meter'.
Tib neeg kuj nug, dab tsi yog ε0 hauv physics?
Lub permittivity ntawm qhov chaw dawb, ε0 , yog lub cev tas li siv feem ntau hauv electromagnetism. Nws sawv cev rau lub peev xwm ntawm lub tshuab nqus tsev tso cai rau hluav taws xob teb. Nws tseem txuas nrog lub zog khaws cia hauv qhov chaw hluav taws xob thiab lub peev xwm. Tej zaum qhov xav tsis thoob, nws yog qhov tseem ceeb cuam tshuam nrog kev ceev ntawm lub teeb.
Tsis tas li ntawd, tus nqi ntawm mu tsis yog dab tsi? tsis muaj nuj nqis : µ0 luas = 4 x 10-7 H/m.
Ntawm no, dab tsi yog SI unit ntawm Epsilon tsis?
Tus nqi ntawm Epsilon Naught Cov kev tso cai ntawm qhov chaw dawb (ε0) yog lub peev xwm ntawm lub tshuab nqus tsev classical tso cai rau hluav taws xob teb. Nws raws li tus nqi txhais tau tias yuav kwv yees li. ε0 = 8.854187817 × 10-12 F.m-1 (Hauv SI Unit ) Sau. ε0 = 8.854187817 × 10-12 C2/N.m2 (In CGS units )
Tus nqi ntawm 1 rau 4 pi epsilon yog dab tsi?
Cov tus nqi ntawm PI yog 3.1415926 los yog 22/7 tab sis cov lus teb ntawm 22/7 yog 3.142857…

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
Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Yuav ua li cas koj thiaj paub yog tias tus nqi tsis sib xws tsis muaj kev daws teeb meem?
Okay, yog tias qhov tseem ceeb tshaj plaws yeej ib txwm zoo lossis xoom tsis muaj txoj hauv kev uas lawv tuaj yeem tsawg dua lossis sib npaug rau tus lej tsis zoo. Yog li ntawd, tsis muaj kev daws teeb meem rau ob qho no. Hauv qhov no yog tias tus nqi tiag tiag yog qhov zoo lossis xoom ces nws yuav nco ntsoov ntau dua lossis sib npaug rau tus lej tsis zoo
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 .
