Kev sib txhuam them nqi txheej txheem ua rau atransfer ntawm electrons ntawm ob yam khoom uas yog rubbed ua ke. Ob yam khoom tau ua raug them nrog kev sib txawv ntawm cov nqi raws li kev hloov pauv ntawm electron los ntawm cov khoom siv hluav taws xob tsawg tshaj plaws rau cov khoom siv hluav taws xob feem ntau nyiam.
Tsis tas li ntawd, vim li cas cov khoom yuav raug them thaum rubbed?
Cov khoom uas tau txais electrons ua tsis zoo raug them . Cov khoom uas poob electrons isleft nrog ib tug zoo nqi . Thaum ib tug pas nrig polythene rubbed Nrog lub plua plav, kev sib txhuam ua rau cov electrons kom muaj zog. Electrons tau txais lub zog txaus kom tawm ntawm lub atom thiab' rub tawm' rau ntawm tus pas nrig polythene.
Tsis tas li ntawd, nws puas tuaj yeem them tus neeg xyuas pib los ntawm rubbing? Insulators tuaj yeem yooj yim raug them los ntawm kev sib txhuam raws li cov electrons ntxiv tau tsis tau yooj yim khiav. Tus coj : cov ntaub ntawv uas tso cai rau cov electrons ntws los ntawm lawv yooj yim. Tus coj TSIS TAU yooj yim raug them los ntawm kev sib txhuam raws li cov electrons ntxiv tau yooj yim khiav. Thaum tsis zoo raug them pas nrig muab tso ze rau ib hlau ua tau
Nyob rau hauv kev hwm rau qhov no, yuav ua li cas them qhov chaw thaum cov tshuaj yog rubbed?
Thaum koj rub ob qhov sib txawv insulating cov ntaub ntawv tiv thaiv ib leeg lawv ua hluav taws xob raug them . Qhov tsis zoo raug them cov khoom hu ua electrons txav los ntawm ib yam khoom rau lwm tus. Cov khoom uas poob electrons yuav zoo raug them . Cov khoom uas tau txais electrons yuav tsis zoo raug them.
Dab tsi yog them los ntawm rubbing thiab them los ntawm induction?
Them los ntawm Induction . Thaum twg them nqi aconductor los ntawm induction , a raug them yam khoom raug coj los ze tab sis tsis kov tus neeg xyuas pib. Electrons ntws los ntawm av mus rau tus neeg xyuas pib yog tias lub raug them Cov khoom yog qhov zoo, thiab qhov sib txawv yog tias qhov khoom tsis zoo.
Pom zoo:
Dab tsi tshwm sim ntawm Theodor Engelmann qhov kev sim nto moo qhia rau nws uas wavelength S yog tus tsav tsheb zoo tshaj plaws ntawm photosynthesis?
Cov kab mob sib sau ua ke ntau tshaj plaws nyob ze ntawm ib feem ntawm cov alga uas tau nthuav tawm cov xim liab thiab xiav wavelengths. Engelmann qhov kev sim ua kom pom tias lub teeb liab thiab xiav yog lub zog zoo tshaj plaws rau photosynthesis
Dab tsi yog them los ntawm rubbing thiab them los ntawm induction?
Friction charging yog ib txoj hauv kev zoo tshaj plaws ntawm kev them cov khoom. Induction charging yog ib txoj kev siv los them cov khoom yam tsis tau kov cov khoom mus rau lwm yam khoom siv
Koj txhais li cas los ntawm kev them nyiaj ntawm tRNA?
Kev them nyiaj yug tRNA. Ua ntej ib qho amino acid tuaj yeem muab tso rau hauv ib qho kev loj hlob ntawm polypeptide, nws yuav tsum xub muab txuas mus rau lub molecule hu ua hloov RNA, los yog tRNA, nyob rau hauv ib tug txheej txheem hu ua tRNA them. Tus nqi tRNA yuav nqa cov activated amino acid mus rau ribosome
Cov tshuaj tiv thaiv dab tsi tshwm sim thaum cawv tsim los ntawm alkene?
Nplooj ntawv no saib ntawm kev tsim cov cawv los ntawm kev tso dej ncaj qha ntawm alkenes - ntxiv dej ncaj qha rau carbon-carbon ob daim ntawv cog lus. Ethanol yog tsim los ntawm reacting ethene nrog chav. Cov tshuaj tiv thaiv yog thim rov qab. Tsuas yog 5% ntawm ethene hloov mus rau hauv ethanol ntawm txhua qhov dhau los ntawm lub reactor
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
