" A biconditional yog muaj tseeb yog tias thiab tsuas yog ob qho tib si xwm txheej muaj tseeb. Bi- xwm txheej yog sawv cev los ntawm lub cim ↔ lossis ⇔.
Tsis tas li ntawd, thaum twg koj tuaj yeem sau Daim Ntawv Qhia Biconditional?
Thaum twg koj muab ib tug conditional nqe lus thiab nws txoj kev sib tham, koj tsim ib biconditional nqe lus . A biconditional nqe lus yog a nqe lus uas ua tau sau rau hauv daim ntawv "p yog thiab tsuas yog q." Qhov no txhais tau tias "yog p, ces q" thiab "yog q, ces p." Cov biconditional "p yog thiab tsuas yog q" ua tau kuj sau ua "p iff q" lossis p? q.
Tsis tas li ntawd, puas tsuas yog Biconditional? IF THIAB YOG YOG , yog a biconditional lus, txhais tau hais tias ob nqe lus muaj tseeb los yog ob qho tib si yog cuav. Yog li nws yog qhov tseem ceeb thiab IF ” nqe lus uas ua haujlwm ob txoj hauv kev.
Kuj tseem yuav paub, cov nqe lus raws cai thiab Biconditional yog dab tsi?
Thaum peb sib tov ob cov lus qhia txoj kev no, peb muaj ib biconditional . Lus txhais: A biconditional nqe lus txhais tau tias muaj tseeb thaum twg ob qho tib si muaj qhov tseeb qhov tseeb. Hauv cov lus tseeb saum toj no, p q yog qhov tseeb thaum p thiab q muaj qhov tseeb qhov tseeb, (piv txwv li, thaum ob qho tib si muaj tseeb lossis ob qho tib si tsis tseeb.)
Ib qho piv txwv ntawm Biconditional nqe lus yog dab tsi?
Biconditional Nqe Lus piv txwv Cov biconditional nqe lus rau ob pawg no yuav yog: Lub polygon tsuas muaj plaub sab yog thiab tsuas yog tias lub polygon yog plaub fab. Lub polygon yog quadrilateral yog thiab tsuas yog tias lub polygon tsuas muaj plaub sab.

Vim li cas Dalton txoj cai yog ib txoj cai txwv?
Kev txwv ntawm Dalton Txoj Cai Txoj cai lij choj tuav tau zoo rau cov pa roj tiag tiag ntawm qhov tsis tshua muaj siab, tab sis ntawm qhov siab, nws deviates loj. Qhov sib xyaw ntawm cov pa roj carbon monoxide yog non-reactive nyob rau hauv cov xwm. Nws kuj tseem xav tias kev sib cuam tshuam ntawm cov molecules ntawm txhua tus neeg cov pa roj yog tib yam li cov molecules hauv qhov sib xyaw
Yuav ua li cas koj hloov txoj cai quotient rau cov cai khoom?
Txoj cai quotient tuaj yeem pom raws li kev siv ntawm cov khoom thiab cov kev cai saw hlau. Yog Q(x) = f(x)/g(x), ces Q(x) = f(x) * 1/(g(x)). Koj tuaj yeem siv txoj cai khoom kom sib txawv Q(x), thiab 1/(g(x)) tuaj yeem sib txawv siv txoj cai saw nrog u = g(x), thiab 1/(g(x)) = 1/u
Vim li cas Lenz txoj cai ua raws li txoj cai ntawm kev txuag hluav taws xob?
Lenz txoj cai yog ua raws li Txoj Cai ntawm Kev txuag hluav taws xob vim tias thaum lub hlau nplaum nrog N-ncej tig lub kauj raug thawb mus rau (los yog rub tawm ntawm) lub kauj, muaj qhov nce (lossis txo) hauv kev sib nqus flux, uas ua rau muaj kev cuam tshuam. tam sim no ntws nyob rau hauv lub cell, raws li Faraday txoj cai
