Siab txhais tau tias yog quab yuam ib unit cheeb tsam . Siab yog inversely proportional rau cheeb tsam , i.e.,ua cheeb tsam nce siab nce.
Ua li no, vim li cas lub siab yog inversely proportional rau cheeb tsam?
Siab yog inversely proportional rau cheeb tsam , yog tias txhua yam nyob twj ywm tib yam. Hauv qhov no, lub zog uas ua rau siab hloov dua siab tshiab rau lwm hom zog, yog li ob leeg siab thiab cheeb tsam txo.
Ib tug kuj yuav nug, yog ntws ncaj qha proportional rau siab? Qhov no yog qhov zoo tshaj plaws qhia tau hais tias nyob rau hauv turbulent ntws , cov ntws tus nqi yog proportional mus rau lub square root ntawm lub siab gradient, hos nyob rau hauv laminar ntws , ntws tus nqi yog ncaj qha proportional mus rau siab gradient. Qhov no txhais tau tias kom muab ob npaug rau ntws , cov siab hla lub raj yuav tsum tau quadrupled.
Dhau li ntawm no, kev sib raug zoo ntawm lub zog siab thiab cheeb tsam yog dab tsi?
Yog muab ib qho tsis tu ncua cheeb tsam tus zog thov yog ncaj qha proportional rau cov siab . Yog tias zog yog nyob tas li tus siab yog inversely proportional rau cov cheeb tsam . Yog tias cheeb tsam yog ob npaug rau siab yog halved. Yog tias siab yog nyob tas li ces tus zog yog ncaj qha proportional rau cov cheeb tsam.
Yuav ua li cas ntws thiab siab sib xws?
Ntws yog ib qho kev ntsuas ntawm cov pa tawm raws li qhov ntim ntawm ib chav tsev ntawm lub sijhawm. Cov chav nyob feem ntau yog taw ib ob, meters ib ob, thiab lwm yam? Siab yog qhov ntsuas ntawm lub zog siv rau ntawm thaj chaw. Common units rau siab yog phaus ib square inch (PSI), Pascals (Newtons ib square meter), thiab lwm yam.

Lub siab puas nce nrog cheeb tsam?
Yog tias koj siv tib lub zog ntawm thaj tsam ntawm 1 sqaure meter, lub siab yog 10 N ib square meter. Yog li, rau tib lub zog, yog tias thaj chaw txo qis, lub siab nce
Lub cheeb tsam twg ntawm Virginia yog lub npe hu rau nws cov coal deposits?
Txoj Kev Appalachian Trail, National Scenic Trail, spans 554 mais ntawm Virginia ridges (van der Leeden). Coal deposits yog tam sim no nyob rau hauv ntau abundance nyob rau hauv Southwest Virginia Coal Field, uas muaj xws li 1,520 square mais nyob rau hauv Buchanan, Dickenson, Wise, Russell, Tazewell, Lee, thiab Scott counties
Yuav ua li cas cov ntaub ntawv nyob rau hauv cov cheeb tsam uas oceanic daim hlau diverge thiab tshiab seafloor yog tsim abyssal plains continental txee continental txoj kab nqes mid hiav txwv ridge?
Lub continental txoj kab nqes thiab nce yog hloov pauv ntawm crustal hom, thiab lub abyssal plain yog underlain los ntawm mafic oceanic crust. Oceanic ridges yog diverging phaj ciam teb qhov twg dej hiav txwv lithosphere tshiab tsim thiab dej hiav txwv trenches yog converging phaj ciam teb uas dej hiav txwv lithosphere yog subducted
Dab tsi yog cheeb tsam hauv lej rau cov menyuam yaus?
Tus nqi ntawm qhov chaw nyob rau hauv ciam teb ntawm ib tug ca (2-dimensional) khoom xws li daim duab peb sab los yog lub voj voog, los yog nto ntawm ib tug khoom (3-dimensional) khoom
Kev nyab xeeb nyob rau hauv cheeb tsam tropical yog dab tsi?
Ib cheeb tsam uas muaj huab cua sov yog ib qho nrog qhov nruab nrab kub siab tshaj 18 degrees Celsius (64 degrees Fahrenheit) thiab nag lossis daus loj heev thaum tsawg kawg ib feem ntawm lub xyoo. Cov cheeb tsam no yog nonnarid thiab feem ntau zoo ib yam nrog equatorial huab cua puag ncig lub ntiaj teb no
