A planetary nebula yog tsim thaum lub hnub qub tshuab tawm nws cov txheej txheem txheej tom qab nws tau khiav tawm ntawm cov roj los hlawv. Cov txheej txheej ntawm cov roj no nthuav mus rau hauv qhov chaw, ua ib qho nebula uas yog feem ntau cov duab ntawm lub nplhaib los yog npuas.
Ib yam li ntawd, koj tuaj yeem nug, nws yuav siv sijhawm ntev npaum li cas rau lub ntiaj teb nebula tsim?
Lub hnub qub dhau los ua neeg dawb, thiab cov huab cua nthuav dav dhau los ua qhov tsis pom rau peb, xaus lub hnub qub hnub qub ntawm kev hloov pauv. Rau ib tug raug planetary nebula, txog 10,000 xyoo dhau ntawm nws tsim thiab recombination ntawm cov ntshav plasma.
Kuj Paub, nebula yog dab tsi thiab nws tsim li cas? A nebula yog huab cua loj heev ntawm plua plav thiab roj hauv qhov chaw. Ib txhia nebula (ntau tshaj ib nebula ) los ntawm cov pa roj thiab hmoov av pov tseg los ntawm kev tawg ntawm lub hnub qub tuag, xws li supernova. Lwm yam nebula yog thaj chaw uas cov hnub qub tshiab pib daim ntawv . Vim li no, ib txhia nebula hu ua "star nurseries."
Tom qab ntawd, lo lus nug yog, yuav ua li cas lub planetary nebula tsim quizlet?
A planetary nebula yog tsim thaum ib tug liab giant ejects nws sab nraum cua. Cov duab zoo nkauj qhia tau tias a planetary nebula yog ib theem nyob rau hauv lub evolution ntawm ib tug tsawg pawg hnub qub. Ib tug neeg dawb huv yog carbon core ntawm ib tug loj heev liab uas tau ejected nws photosphere raws li ib tug planetary nebula.
Yuav ua li cas ci ib tug planetary nebula?
Planetary nebulae Nws muaj qhov ntom ntom ntau dua li thaj tsam H II, feem ntau muaj 1, 000-10, 000 atoms ib cubic cm nyob rau hauv lawv cov cheeb tsam tuab, thiab muaj qhov ci ntsa iab 1, 000 lub sij hawm loj dua. High-resolution duab ntawm a planetary nebula feem ntau nthuav tawm cov pob me me thiab filaments mus rau qhov kev daws teeb meem.

Lub planetary nebula loj npaum li cas?
Kwv yees li ib lub xyoo kaj
Yuav ua li cas ib tug planetary nebula tsim quizlet?
Lub planetary nebula yog tsim thaum lub loj loj liab ejects nws sab nrauv. Cov duab zoo nkauj qhia tau hais tias lub ntiaj teb nebula yog ib theem hauv kev hloov pauv ntawm lub hnub qub qis. Ib tug dwarf dawb yog cov carbon core ntawm ib tug liab giant uas tau ejected nws photosphere raws li ib tug planetary nebula
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Puas yog planetary nebulae tsim cov ntiaj chaw?
Planetary Nebula: Gas thiab plua plav, thiab tsis muaj ntiaj chaw koom nrog. Nyob rau hauv li 5 billion xyoo, thaum lub hnub shucks tawm nws txheej txheej, nws yuav tsim ib tug zoo nkauj lub plhaub ntawm diffuse gas hu ua ib tug planetary nebula
Niels Bohr nrhiav tau lub planetary qauv li cas?
Bohr Atomic Model: Xyoo 1913 Bohr tau npaj nws lub plhaub qauv ntawm lub atom los piav qhia seb cov hluav taws xob tuaj yeem muaj qhov chaw ruaj khov nyob ib puag ncig lub nucleus. Lub zog ntawm ib qho hluav taws xob nyob ntawm qhov loj ntawm lub orbit thiab qis dua rau cov orbits me. Radiation tuaj yeem tshwm sim tsuas yog thaum lub electron dhia ntawm ib lub orbit mus rau lwm qhov
