Lub phenomenon uas cia oobleck ua ua qhov nws ua yog hu ua "shear thickening," ib txheej txheem uas tshwm sim nyob rau hauv cov ntaub ntawv uas ua los ntawm microscopic cov khoom uas raug tshem tawm hauv cov kua. Piv txwv li drilling av nkos siv hauv cov roj qhov dej thiab cov kua dej siv rau ob peb lub tsheb kis mus rau lub log.
Ua raws li qhov xav tau, lub hom phiaj ntawm Oobleck yog dab tsi?
Oobleck yog ib qho mis-dawb, ci iab khoom hu ua non-Newtonian kua. Nws ntws zoo li cov xim tuab thaum koj nchuav nws, tab sis txhuam koj txhais tes rau ntawm nws qhov chaw thiab nws ua rau tawv nqaij tawv. Nyem ib co ntawm koj xib teg thiab nws yuav tsim ib tug tawv glob. Tab sis qhov thib ob koj tso nws, oobleck trickles cia tshaj koj cov ntiv tes nyob rau hauv ib tug slurry.
Oobleck science yog dab tsi? Oobleck yog ib qho kev ncua, lossis ib yam khoom uas tuaj yeem ua raws li qhov zoo ntawm cov khoom lossis cov kua. Cov ntaub ntawv no tseem raug cais raws li cov kua dej tsis yog-Newtonian. Cov kua Newtonian muaj qhov viscosity tas li, xws li dej lossis roj av. Raws li koj tuaj yeem twv, viscosity ntawm cov kua uas tsis yog-Newtonian hloov pauv.
Raws li, Oobleck yog ib qho khoom lossis kua?
Oobleck yog cov kua uas tsis yog-Newtonian; nws muaj zog ntawm ob qho tib si kua thiab cov khoom khov. Koj tuaj yeem maj mam muab koj txhais tes rau hauv nws zoo li ib qho ua kua , tab sis yog tias koj nyem lub oobleck ua los yog xuas nrig ntaus nws, nws yuav hnov khov kho . Lub npe oobleck los ntawm Dr.
Vim li cas Oobleck yog ib qho kev ncua?
Siv zog, xws li nyem los yog tapping nws, yuav ua rau oobleck ua kom muaj zog ntau dua, thaum tsuas yog tuav hauv koj txhais tes yuav ua oobleck ua xav zoo li kua. Tus goo no hu ua a kev ncua , txhais tau hais tias cov nplej ntawm starch tsis yaj tab sis theej ncua thiab nthuav tawm hauv dej.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
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 sij hawm scientific rau Oobleck yog dab tsi?
Ib yam khoom uas ua tau zoo li cov kua, thiab tuaj yeem nchuav, tab sis qhov ntawd ua zoo li cov khoom thaum koj siv zog rau nws los ntawm kev thawb nws los yog nyem nws. Nws yog tsim los ntawm kev sib xyaw cornflour (tseem hu ua cornstarch) nrog dej. Oobleck yog cov kua uas tsis yog-Newtonian
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
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
