1909
Ib yam li ntawd, Rutherford scattering sim yog dab tsi?
Rutherford's alpha particle scattering xyaum sim hloov txoj kev peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog lub nuclei ntawm helium atoms thiab li no zoo them) ntawm nyias cov ntawv ci kub los kuaj cov qauv no thiab sau tseg tias alpha hais li cas tawg tawg los ntawm foil.
Tsis tas li ntawd, vim li cas thiaj li Ernest Rutherford ua cov ntawv nyiaj kub? Rutherford's Gold Foil Experiment Ua pov thawj qhov muaj nyob ntawm qhov chaw me me loj rau atoms, uas tom qab ntawd yuav raug hu ua lub nucleus ntawm atom. Ernest Rutherford , Hans Geiger thiab Ernest Marsden tau ua tiav lawv Kub Foil Experiment los soj ntsuam cov nyhuv ntawm alpha hais txog qhov teeb meem.
Ib yam li ntawd, thaum twg Rutherford ua cov ntawv nyiaj kub?
1908 thiab 1913
Qhov txiaj ntsig ntawm Rutherford sim ua li cas?
Thomson's plum pudding qauv ntawm lub atom muaj qhov tsis zoo-them electrons embedded nyob rau hauv ib tug zoo-them "kua zaub." Rutherford's gold foil xyaum sim qhia tau hais tias lub atom feem ntau yog qhov chaw khoob nrog me me, ntom, zoo-them nucleus. Raws li cov no tshwm sim , Rutherford tau npaj cov qauv nuclear ntawm lub atom.

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
Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo

Rutherford's alpha particle scattering xyaum sim hloov qhov peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog cov nuclei ntawm helium atoms thiab yog li them zoo) ntawm cov ntawv ci kub nyias los kuaj cov qauv no thiab sau tseg tias cov alpha hais li cas tawg los ntawm cov ntawv ci
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
