Raws li cov roj teeb yog tso tawm cov electrolyte concentration yog txo, ua dej ntshiab thaum lub roj teeb raug tso tawm tag nrho. Yog vim li cas qhov kev hloov pauv hauv electrolyte concentration roj teeb kuj nce thaum tso tawm. Kev poob ntawm electrolyte kuj yog ib txwm ua rau nce electrolyte tsis kam.
Tom qab ntawd, dab tsi ua rau kev tiv thaiv sab hauv hauv lub roj teeb?
Sulfation thiab daim phiaj corrosion yog lub ntsiab contributors rau qhov nce ntawm lub sab hauv tsis kam nrog lead acid. Kub kuj cuam tshuam rau tsis kam ; cua sov txo nws thiab txias tsa nws. Cua sov lub roj teeb yuav txo qis lub sijhawm sab hauv tsis kam los muab lub sijhawm ua haujlwm ntxiv.
Ib yam li ntawd, puas muaj kev tiv thaiv sab hauv ntawm lub roj teeb hloov? Cov tsis kam lead acid mus nrog tawm. Cov tsis kam hloov nruab nrab ntawm tag nrho cov nqi thiab tawm yog hais txog 40%. Txias kub tsub kom sab hauv tsis kam ntawm tag nrho roj teeb thiab ntxiv txog 50% ntawm +30 ° C thiab -18 ° C rau cov kua qaub roj teeb.
Ib yam li ntawd ib tug yuav nug, yuav ua li cas tshwm sim thaum lub zog sab hauv nce?
Raws li cov tsis kam ntawm qhov sib txawv resistor yog nce , tam sim no los ntawm Circuit Court poob. (Raws li siv E = I (R + r), rau emf E kom nyob twj ywm, yog R nce , tam sim no kuv yuav tsum txo). Yog li ntawd, voltage nyob rau hauv lub terminals nce (raws li tsawg yog nkim thoob lub sab hauv resistor ).
Puas muaj qhov muaj peev xwm nce ntxiv hauv kev tawm tsam ntawm lub cell Vim li cas?
Cov tshuaj tiv thaiv uas tshwm sim hauv a roj teeb yog lub qhov tseem ceeb ntawm nce kev tiv thaiv sab hauv ntawm lub roj teeb los ntawm nce ntawm lub sijhawm. Vim li ntawd lub internal voltage poob thiab nce uas ua rau txo qis tus Terminal voltage ntawm lub roj teeb …

Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Lub zog thauj mus sab nraud li cas hauv lub hnub sab hauv quizlet?
Lub zog txav mus los ntawm cov txheej txheej tob tshaj plaws ntawm lub hnub - lub hauv paus thiab thaj chaw tawg - nyob rau hauv daim ntawv ntawm randomly bouncing photons. Tom qab lub zog tawm ntawm qhov chaw hluav taws xob, convection nqa nws txoj kev mus rau photosphere, qhov twg nws tau tawg mus rau hauv qhov chaw raws li lub hnub ci
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
Yuav ua li cas koj pom lub sab hauv ntawm lub kaum sab xis?
