Kab rov tav kab tiag tiag yog hu ua lub x- axis , txoj kab tiag tiag yog hu ua y- axis thiab cov taw tes ntawm kev sib tshuam yog hu ua lub hauv paus. Yog ib lus dag pe x- axis ces nws y-coordinate yog 0. Ib yam li ntawd, a taw tes pe y- axis muaj nws x-coordinate 0. Lub hauv paus chiv keeb muaj coordinates (0, 0).
Ua li no, lub quadrant lossis axis yog dab tsi?
Cov cov axes ntawm ob-dimensional Cartesian system faib lub dav hlau mus rau hauv plaub cheeb tsam infinite, hu ua quadrants , txhua bounded los ntawm ob ib nrab- cov axes . Cov no feem ntau suav los ntawm 1st mus rau 4th thiab qhia los ntawm Roman tus lej: Kuv (qhov twg cov cim ntawm (x; y) kev tswj hwm yog kuv (+; +), II (−; +), III (−; −), thiab IV (+; −).
Tom qab ntawd, lo lus nug yog, yog Quadrant 1 zoo lossis tsis zoo? Hauv Quadrant I, ob qho tib si x- thiab y-coordinates yog qhov zoo; hauv Quadrant II , x-coordinate yog qhov tsis zoo, tab sis y-coordinate yog qhov zoo; hauv Quadrant III ob leeg tsis zoo; thiab hauv Quadrant IV, x yog qhov zoo tab sis y yog qhov tsis zoo.
Ntawm no, ntawm qhov axis twg yog qhov point 0 3 dag?
Yog li, cov lus teb rau koj cov lus nug yog tias ( 0 , 3 ) lus dag pe y- axis.
Lub ntsiab lus twg tsis dag nyob rau hauv ib qho quadrant?
Nco ntsoov tias cov ntsiab lus uas dag ntawm ib axis tsis txhob dag nyob rau hauv tej quadrant . Yog ib lus dag ntawm x-axis ces nws y-coordinate yog 0. Ib yam li ntawd, a taw tes ntawm y-axis muaj nws x-coordinate 0. Lub hauv paus chiv keeb muaj kev tswj hwm (0, 0).

Dab tsi yog lub ntsiab lus ntawm ib pab pawg ntawm cov lus teev sijhawm?
Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
