Tsis tas li ntawd, vim li cas nws tseem ceeb heev uas yuav tsum siv lub khob dov es tsis txhob siv hlau?
stirring rods yog tseem ceeb vim nplawm ib qho kev daws teeb meem, uas tseem hu ua kev ntxhov siab, ua rau muaj kev tshwm sim sai dua. iav rods kuj yog siv kom kis tau cov khoom ua kua rau ntawm qhov chaw. Nws yog qhov zoo dua rau a hlau rod vim iav tsis yog ib tug zoo conductor ntawm tshav kub thiab hlau yog. Hlau muaj dawb electrons.
Vim li cas nws thiaj li yuav tsum tau ntxuav cov tshuaj tawm ntawm tus pas nrig nplawm rau hauv lub beaker? Txhawm rau kom nrawm nrawm ntawm sodium carbonate, thiab tiv thaiv kev tsim cov pob txha ntawm cov khoom. (iii) Yog vim li cas thiaj li yuav tsum tau ntxuav cov tshuaj tawm ntawm tus pas nrig nplawm rau hauv lub beaker ? Kom paub meej tias tag nrho cov sodium carbonate daws yog pauv mus rau lub hwj chim volumetric.
Ua li no, ntau npaum li cas yog ib khob nplawm pas nrig?

Vim li cas daim iav convex siv los ua daim iav saib tom qab?
Convex mirrors feem ntau yog siv los ua rear-saib (tis) iav hauv tsheb vim hais tias lawv muab ib qho erect, virtual, tag nrho cov duab ploj zuj zus ntawm cov khoom nyob deb nrog kev pom dav dua. Yog li, daim iav convex ua rau tus neeg tsav tsheb pom thaj tsam loj dua li qhov yuav ua tau nrog daim iav dav hlau
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Lub lens twg yog siv rau hauv tsom iav raj?
Hom telescope no hu ua refracting telescope.Feem ntau refracting telescopes siv ob lub ntsiab lo ntsiab muag. Qhov loj tshaj plaws yog hu ua lub hom phiaj lens, thiab lub lens me dua siv rau kev saib yog hu ua eyepiece lens
Ob hom iav iav yog dab tsi?
Thaum lub reflecting nto yog hloov nkhaus, peb hu nws lub iav nkhaus. Muaj ob hom iav nkhaus; concave thiab convex daim iav. Cov iav nkhaus uas muaj qhov cuam tshuam ntawm qhov chaw nkhaus sab hauv yog hu ua concave mirrors thaum cov uas nws xav txog qhov chaw tawm sab nraud yog hu ua convex mirrors
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
