Cov Tshuab xam zauv ceev siv tus qauv p=m/V, los yog ceev (p) yog sib npaug rau qhov loj (m) faib los ntawm ntim (V). Cov tshuab xam zauv tuaj yeem siv ob qho ntawm qhov tseem ceeb rau xam peb. Qhov ntom txhais tau tias yog huab hwm coj ib unit ntim.
Tsuas yog li ntawd, koj yuav nrhiav tau qhov ceev li cas?
Qhov ntom . Rau nrhiav qhov ntom ntawm txhua yam khoom, koj yuav tsum paub qhov Mass (grams) ntawm cov khoom, thiab nws qhov Volume (ntsuas hauv mL lossis cm³). Faib qhov loj los ntawm lub ntim thiaj li yuav tau ib object Qhov ntom.
Ib yam li ntawd, koj ua li cas xam shipping ceev? Yuav ua li cas xam Freight Density rau Shipping
- Ntsuas qhov siab, dav, thiab qhov tob ntawm cov khoom xa tuaj hauv inches.
- Muab peb qhov ntsuas (qhov siab x dav x qhov tob).
- Faib tag nrho cubic inches los ntawm 1,728 (tus naj npawb ntawm cubic inches hauv ib cubic feet).
- Faib qhov hnyav (hauv phaus) ntawm cov khoom xa tuaj los ntawm tag nrho cov cubic feet.
Ib tug kuj nug, ua li cas koj pom qhov hnyav uas siv qhov ntom ntom?
Koj ua tau txiav txim nws hnyav yooj yim los ntawm kev muab cov ceev los ntawm qhov loj, lossis ntim, ntawm cov khoom. Sau qhov ntim thiab cov ceev ntawm qhov khoom koj ntsuas.
Qhov ntsuas qhov ceev npaum li cas hauv?
Cov mis rau qhov ntom yog d = M / V, qhov twg d yog ntom, M yog loj, thiab V yog ntim. Qhov ceev yog feem ntau qhia nyob rau hauv units ntawm grams rau kub cm . Piv txwv li, qhov ntom ntawm cov dej yog 1 grams rau kub cm , thiab lub ntiaj teb qhov ceev yog 5.51 grams rau kub cm.

Yuav ua li cas koj xam qhov ceev ntawm electromagnetic tawg?
Qhov ceev ntawm txhua lub sijhawm yoj yog qhov khoom ntawm nws qhov wavelength thiab zaus. v = λf. Qhov ceev ntawm ib qho hluav taws xob nthwv dej hauv qhov chaw dawb yog qhov ceev ntawm lub teeb c = 3 * 108 m / s. Electromagnetic nthwv dej tuaj yeem muaj qhov wavelength λ los yog zaus f ntev li λf = c
Kuv yuav nrhiav tau qhov latitude thiab longitude ntawm kuv qhov chaw yug li cas?
Txhawm rau nrhiav koj qhov longitude thiab latitude ntawm koj qhov chaw yug, thov ntaus koj Lub Nroog Yug thiab Lub Tebchaws lossis nws cov ntawv xa / zipcode hauv World Atlas thiab nias Xa. Tom qab ntawd koj yuav tau txais Latitude thiab Longittitude ntawm qhov chaw ntawd. Latitude yog North lossis South (N / S)
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Kuv yuav xam qhov chaw ntawm kuv lub pas dej li cas?
Ntev lub sij hawm dav muab thaj tsam ntawm lub pas dej. Multiplying uas los ntawm qhov nruab nrab qhov tob muab qhov ntim hauv cubic feet. Txij li thaum muaj 7.5 nkas loos hauv txhua qhov cubic taw, muab cov cubic feet ntawm lub pas dej ua ke los ntawm 7.5 kom txog rau qhov ntim ntawm lub pas dej (hais hauv nkas loos)
Kuv yuav ua li cas thiaj paub tseeb tias kuv qhov ntsuas digital yog qhov tseeb?
Ntsuas ob yam khoom ua ke. Muab ib qho khoom tso rau ntawm qhov ntsuas. Nco ntsoov qhov hnyav. Tshem nws tawm thiab cia lub nplai txawm rov qab tawm. Yog tias nws phim, qhov ntsuas yog qhov tseeb. Yog tias nws tsis yog, sim dua thiab saib seb nws puas tawm los ntawm tib tus lej. Yog tias nws yog, nws yuav yog tias koj qhov ntsuas ib txwm tawm ntawm tus nqi ntawd
