Qhov chaw khoom nyob rau hauv lub cylinder kawm tiav, thiab sau cov txiaj ntsig dej ntim as "b." Tshem tawm cov ntim ntawm dej ib leeg los ntawm ntim ntawm dej ntxiv rau khoom . Piv txwv li, yog tias "b" yog 50 milliliters thiab "a" yog 25 milliliters, ntim ntawm irregularly zoo li tus kwv yuav yog 25 milliliters.
Yog li ntawd, koj yuav ntsuas qhov ntim ntawm cov khoom tsis sib xws uas ntab saum dej ntawm ib daim ntoo?
Ib txoj kev mus ntsuas qhov ntim ntawm ib yam khoom ntawd ntab hauv dej yog los luj nws nrog ib yam khoom hnyav. Qhov tseem ceeb yog ua ntej ntsuas tus dej theem nrog cov khoom hnyav submerged nyob rau hauv nws, ces ntsuas tus dej theem nrog cov khoom hnyav tuav cov khoom ntab hauv qab dej.
Ib yam li ntawd, koj ntsuas qhov ntim ntawm ib yam khoom li cas? Yuav nrhiav tau ntim ntawm ib daim duab plaub khoom , ntsuas qhov ntev, dav thiab qhov siab. Muab qhov ntev ntawm qhov dav thiab muab qhov tshwm sim los ntawm qhov siab. Qhov tshwm sim yog qhov ntim . Muab qhov tshwm sim hauv cubic units, xws li cubic centimeters.
Ib yam li ntawd, cov mis hloov dej yog dab tsi?
Siv cov qauv qhov kawg ntim rho tawm pib ntim (vf -vi) yields lub ntim ntawm cov khoom. Yog thawj qhov ntim ntawm dej yog 900 ml dej thiab qhov kawg ntim ntawm dej sib npaug 1, 250 ml, qhov ntim ntawm cov khoom yog 1250 - 900 = 350 ml, txhais tau tias qhov ntim ntawm cov khoom sib npaug 350 cm3.
Koj pom qhov kev hloov pauv li cas?
Rau xam kev khiav tawm , tsuas yog kos ib vector los ntawm koj qhov chaw pib mus rau koj txoj haujlwm kawg thiab daws qhov ntev ntawm kab no. Yog tias koj txoj haujlwm pib thiab xaus yog tib yam, zoo li koj txoj kev ncig 5K, ces koj hloov chaw yog 0. Nyob rau hauv physics, hloov chaw yog sawv cev los ntawm Δs.

Dab tsi yog qhov hloov pauv kev sib raug zoo ntawm ntim thiab thaj chaw saum npoo raws li qhov khoom loj dua?
Raws li lub voos xwmfab loj zuj zus los yog lub xov tooj ntawm tes tau loj dua, ces thaj tsam ntawm qhov ntim rau qhov sib piv - SA: V piv txo. Thaum ib yam khoom / cell me me, nws muaj thaj tsam loj rau qhov ntim piv, thaum lub khoom loj / cell muaj thaj tsam me me rau qhov ntim piv
Yuav siv txoj hauv kev twg los txiav txim qhov purity ntawm txhua yam ntawm koj cov khoom uas tau rov qab los?
Cov txheej txheem tshuaj yooj yim tshaj plaws suav nrog gravimetry thiab titration. Kuj tseem muaj ntau txoj kev teeb pom kev zoo los yog spectroscopic, xws li UV-VIS spectroscopy, nuclear magnetic resonance thiab infrared spectroscopy. Cov txheej txheem chromatographic, xws li roj chromatography thiab kua chromatography, kuj tseem siv tau
Albert Einstein txoj kev xav ntawm kev sib raug zoo hloov txoj cai ntawm kev txuag hluav taws xob li cas?
Albert Einstein txoj kev xav ntawm kev txheeb ze hloov txoj cai ntawm kev txuag hluav taws xob li cas? Thaum ib yam khoom lossis lub cev ua haujlwm rau lwm yam khoom, qee qhov ntawm nws lub zog raug xa mus rau qhov khoom ntawd
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?
