Physicist Ernest Rutherford tau tsim lub tswv yim nuclear ntawm lub atom nrog nws kub - foil kev sim . Thaum nws tua ib tug beam ntawm alpha hais ntawm ib daim ntawv ntawm ntawv ci , ib co ntawm cov hais tau deflected. Nws xaus lus tias ib tug me me, ntom nucleus ua rau deflections.
Tsis tas li ntawd, qhov kev sim ntawm cov ntawv ci kub yog dab tsi thiab nws tau ua pov thawj li cas?
Rutherford tus Kub Foil Kev sim ua pov thawj Lub hav zoov ntawm qhov chaw me me loj rau atoms, uas tom qab ntawd yuav raug hu ua lub nucleus ntawm lub atom. Ernest Rutherford, Hans Geiger thiab Ernest Marsden tau ua lawv Kub Foil Experiment los soj ntsuam cov nyhuv ntawm alpha hais txog qhov teeb meem.
Ib sab saum toj no, thaum twg cov ntawv nyiaj kub tau tshwm sim? Lawv txiav txim siab qhov no los ntawm kev ntsuas li cas ib qho alpha particle beam tawg tawg thaum nws ntaus cov hlau nyias. ntawv ci . Cov kev sim tau ua nyob nruab nrab ntawm 1908 thiab 1913 los ntawm Hans Geiger thiab Ernest Marsden nyob rau hauv kev coj ntawm Ernest Rutherford ntawm lub cev Laboratories ntawm University of Manchester.
Tsis tas li ntawd, Rutherford sim ua dab tsi thiab nws nrhiav tau dab tsi?
Rutherford overturned Thomson tus qauv xyoo 1911 nrog nws cov neeg paub zoo kub foil sim hauv qhov twg nws qhia tau hais tias lub atom muaj ib tug me me thiab hnyav nucleus. Rutherford tsim ib kev sim siv cov alpha hais tawm los ntawm cov khoom siv hluav taws xob raws li kev sojntsuam mus rau lub ntiaj teb tsis pom ntawm cov qauv atomic.
Vim li cas Rutherford siv ib daim ntawv nyias nyias?
Rutherford siv kub rau nws qhov kev sim tawg vim kub yog cov hlau malleable tshaj plaws thiab nws xav tau txheej thinnest li sai tau. Lub goldsheet siv yog nyob ib ncig ntawm 1000 atoms tuab. Yog li ntawd, Rutherford xaiv a Ntawv nyiaj kub hauv nws qhov kev sim alpha scattering. Heev heev nyias kub ntawv ci.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Yuav ua li cas tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
Thaum lub ntiaj teb lub hnub thiab lub hli nyob rau hauv txoj kab ncaj nraim, hom tides tshwm sim li cas?
Lub hnub lub ntiajteb txawj nqus rub lub ntiaj teb, thiab. Ob zaug ib xyoos, lub hnub, lub hli, thiab lub ntiaj teb nyob rau hauv ib txoj kab ncaj nraim, thiab tshwj xeeb tshaj yog cov dej ntws. Cov tides caij nplooj ntoos hlav no tshwm sim vim lub hnub thiab lub hli lub ntiajteb txawj nqus ua ke. Tsis muaj zog, lossis tsis muaj zog, dej ntws tshwm sim thaum lub hnub, Lub hli, thiab lub ntiaj teb tsim L-zoo li
Yuav ua li cas tshwm sim rau resistors nyob rau hauv parallel?
Resistors nyob rau hauv parallel - Thaum cov resistors txuas nrog nyob rau hauv parallel, cov khoom tam sim no sib npaug rau cov sum ntawm cov tam sim no los ntawm txhua tus resistor. Thaum cov resistors txuas nrog nyob rau hauv parallel, lawv muaj peev xwm sib txawv ntawm lawv
