Tus qauv ntsuas hluav taws xob (E-field) lub zog yog qhov volt ib 'meter' ( V / m ). Lub volt ib meter, los yog ib co fractional unit raws li nws, yog siv raws li ib tug txhais tau tias ntawm kev qhia qhov siv ntawm electromagnetic teb (EM field) tsim los ntawm lub xov tooj cua transmitter.
Ua li no, VM txhais li cas slang?
VM txhais tau tias "Voice Mail" Yog li tam sim no koj paub - VM txhais tau tias "Voice Mail" - tsis txhob ua tsaug rau peb. YW! VM txhais li cas ? VM yog ib tug acronym, abbreviation los yog lus lo lus uas tau piav saum toj no qhov twg VM txhais yog muab.
Puas yog volts ib meter tib yam li Newtons rau Coulomb? Hloov newton / coulomb [N/C] hluav taws xob / meter [V/ m ] A Newton per coulomb (N/C) yog SI muab tau los ntawm lub zog ntawm hluav taws xob teb. Lub zog ntawm 1 N / C yog ua tiav yog tias a hluav taws xob ntawm 1 V yog siv los ntawm ob lub dav hlau uas tsis muaj qhov sib npaug sib npaug 1 m sib nrug.
Tseem yuav paub yog, V m zoo ib yam li N C?
Tab sis ib tug "Joule per Coulomb" (J / C ) kuj tseem hu ua volt ( V ), thiab lub peev xwm hluav taws xob yog li feem ntau hu ua qhov voltage. Yog li ntawd, hluav taws xob teb kuj tuaj yeem hais nyob rau hauv units ntawm volts ib 'meter', txij li thaum V / m = N / C . Li no ib tug electron volt sib npaug 1.602E-19 J.
Qhov twg hauv qab no muaj chav ntsuas Volt los ntawm Metre?
Lub cev muaj nuj nqis uas nws chav tsev SI yog VOLT PER METER yog " hluav taws xob teb " Ib qho E teb ntawm 1 V / m yog sawv cev los ntawm qhov sib txawv ntawm 1 Volt uas twb muaj lawm ntawm ob lub ntsiab lus uas yog 1 m sib nrug. Thiab nws cov vector kom muaj nuj nqis.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
