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)

  3. Txiav txim siab hloov pauv yam xav tau.
  4. Xyuas kom tseeb tias cov kev hloov pauv hloov nyob rau hauv cov hom ntawv raug.
  5. Tso tseg cov chav uas tshwm sim hauv ob qho tib si tus lej thiab tus lej.
  6. Simplify cov feem.
  7. 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.
