Cov kev cai hauv paus yog dab tsi rau ntsuas qhov ntsuas ? Thaum koj nrog qhov ntev , koj nyob nraum nrog kev taw qhia. Dav, ntev, qhov siab thiab linear lub sij hawm tag nrho muaj ib qho kev taw qhia vector ua rau lawv qhov ntev . Yog tias koj tsis tuaj yeem txheeb xyuas qhov kev taw qhia, koj tsis tau txheeb xyuas qhov loj me, ib yam nkaus.
Kuj nug, dab tsi yog cov kauj ruam ntawm kev tsom xam?
Cov ntsiab lus hauv cov teeb no (7)
- Txheeb xyuas qhov pib qhov tseem ceeb.
- Txheeb xyuas cov ntsiab lus teb.
- Txiav txim siab hloov pauv yam xav tau.
- Xyuas kom tseeb tias cov kev hloov pauv hloov nyob rau hauv cov hom ntawv raug.
- Tso tseg cov chav uas tshwm sim hauv ob qho tib si tus lej thiab tus lej.
- Simplify cov feem.
- daws.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov tseem ceeb ntawm kev tsom xam qhov ntev? Dimensional Analysis yog ib qho tseem ceeb heev ntawm kev ntsuas thiab muaj ntau yam kev siv hauv lub neej tiag tiag physics. Peb siv ntsuas qhov ntsuas rau peb lub laj thawj tseem ceeb, lawv yog: Consistency of a qhov seem kev sib npaug. Muab kev sib raug zoo ntawm lub cev kom muaj nuj nqis hauv lub cev phenomena.
Kuj Paub, dab tsi yog qhov kev txwv ntawm qhov ntsuas qhov ntev?
Nws tsis tuaj yeem muab kev sib raug zoo lossis cov qauv yog tias lub cev muaj nuj nqis nyob ntawm ntau tshaj peb yam uas muaj qhov ntev. Nws tsis tuaj yeem muab cov qauv uas muaj trigonometric muaj nuj nqi, exponential muaj nuj nqi, thiab logarithmic muaj nuj nqi. Nws tsis tuaj yeem muab qhov kev sib raug zoo uas muaj ntau tshaj ib feem hauv qhov sib npaug.
Thawj kauj ruam hauv kev tsom xam yog dab tsi?
Koj yuav txheeb xyuas 3.41 grams raws li muab. Cov thawj kauj ruam yog ib txwm muab qhov muab tso rau pem hauv ntej ntawm koj qhov sib npaug. Tom qab ntawd nrhiav tus piv uas yuav pab koj hloov cov units ntawm grams rau atoms. Raws li tej zaum koj twb tau twv lawm, koj yuav tsum siv ob peb qhov sib piv los pab koj hauv qhov teeb meem no.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Dab tsi yog cov kev siv ntawm gravimetric tsom xam?
Kev siv Gravimetric tsom xam. Gravimetric tsom xam yog cov txheej txheem uas yog siv los ntsuas tus nqi ntawm cov tshuaj analytes lossis theej cov ion raug tshuaj xyuas. Cov txheej txheem siv qhov loj ntawm cov tshuaj ntsuam xyuas los ua tus nqi. Tsis tas li ntawd, cov txheej txheem yog nyob ntawm qhov loj ntawm ob lub tebchaw uas muaj cov tshuaj ntsuam xyuas
Newton txoj cai thib ob hauv cov ntsiab lus yooj yim yog dab tsi?
Newton txoj cai thib ob hais tias kev nrawm ntawm ib qho yog nyob ntawm lub zog ua raws li cov khoom thiab cov khoom loj. Rau ib tug muab particle, yog hais tias lub net quab yuam yog nce, lub acceleration yog nce. Rau ib tug muab net quab yuam, qhov ntau npaum li cas ib tug particle muaj, qhov tsawg acceleration nws muaj
Dab tsi yog kev tsom xam zaus hauv cryptography?
Hauv cryptanalysis, kev txheeb xyuas zaus (tseem hu ua suav cov ntawv) yog kev kawm txog qhov zaus ntawm cov ntawv lossis pawg ntawm cov ntawv hauv cov ntawv ciphertext. Cov txheej txheem yog siv los ua ib qho kev pab cuam rau kev rhuav tshem classical ciphers
Dab tsi yog morphological tsom xam hauv kev tsim?
Morphological tsom xam yog ib txoj kev siv heev thaum koj yuav tsum txheeb xyuas lossis decompose cov qauv lossis cov qauv ntawm cov khoom rau hauv lawv cov duab sib txawv. Cov duab zoo li no tuaj yeem cuam tshuam rau ib lossis ntau qhov tshwj xeeb ntawm cov khoom
