Cov tus nqi kiag muaj nuj nqi | | yog txhais los ntawm. Cov tus nqi kiag ntawm x muab qhov kev ncua deb ntawm x thiab 0. Nws yeej ib txwm zoo los yog xoom. Piv txwv li, |3| = 3, |-3| = 3, | 0 | = 0.
Kuj kom paub yog, dab tsi yog qhov kev sib npaug ntawm tus nqi?
Ib tus nqi sib npaug yog ib kev sib npaug uas muaj ib tus nqi kiag kev qhia. Cov kev sib npaug . |x|=a. Muaj ob txoj kev daws teeb meem x = a thiab x = -a vim tias ob tus lej nyob ntawm qhov deb ntawm 0. Los daws qhov tus nqi sib npaug raws li.
Tsis tas li ntawd, cov kev cai rau tus nqi tiag yog dab tsi? Thaum peb muab lub tus nqi kiag ntawm tus lej, peb ib txwm xaus nrog tus lej zoo (lossis xoom). Txawm hais tias qhov kev tawm tswv yim yog qhov zoo lossis tsis zoo (lossis xoom), cov zis yog ib txwm zoo (lossis xoom). Piv txwv li, | 3 | = 3, thiab | –3 | = 3 too.
Hais txog qhov no, dab tsi yog tus nqi tiag tiag siv rau?
Thaum koj pom ib tus nqi kiag nyob rau hauv ib qho teeb meem los yog sib npaug, nws txhais tau hais tias txawm nyob rau hauv lub tus nqi kiag yog ib txwm zoo. Qhov tseem ceeb feem ntau siv hauv teeb meem cuam tshuam nrog kev deb thiab qee zaum siv nrog kev tsis sib xws.
Yuav ua li cas koj sau ib qho kev sib npaug tag nrho?
SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)
- Kauj Ruam 1: Tshem tawm qhov kev qhia tus nqi tiag.
- Kauj ruam 2: Teem kom muaj nuj nqis nyob rau hauv qhov tseeb tus nqi notation sib npaug rau + thiab - kom muaj nuj nqis nyob rau sab nraud ntawm qhov sib npaug.
- Kauj Ruam 3: daws qhov tsis paub hauv ob qho tib si sib npaug.
- Kauj Ruam 4: Tshawb xyuas koj cov lus teb analytically lossis graphically.

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 nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
