Super-loj heev qhov dub nyob rau hauv cov chaw ntawm ib co active galaxies tsim muaj zog dav hlau ntawm hluav taws xob thiab hais mus ze rau qhov ceev ntawm lub teeb. Attracted los ntawm lub ntiajteb txawj nqus muaj zog, teeb meem ntog mus rau hauv nruab nrab qhov dub raws li nws pub rau ib puag ncig cov pa roj thiab hmoov av.
Hauv qhov no, lub dav hlau ntawm lub qhov dub yog dab tsi?
Relativistic dav hlau yog kab teeb ntawm ionised teeb meem nrawm ze rau qhov ceev ntawm lub teeb. Feem ntau tau soj ntsuam nrog rau hauv nruab nrab qhov dub Ntawm qee lub galaxies nquag, xov tooj cua galaxies lossis quasars, thiab tseem los ntawm galactic stellar qhov dub , neutron hnub qub los yog pulsars.
Tom qab ntawd, lo lus nug yog, nws hu ua dab tsi thaum lub qhov dub tso tawm lub zog? Hawking hluav taws xob yog dub - lub cev hluav taws xob uas tau kwv yees ua tso tawm los ntawm qhov dub , vim quantum cuam tshuam ze ntawm qhov dub xwm txheej qab ntug. Hawking hluav taws xob txo qhov loj thiab kev sib hloov zog ntawm qhov dub thiab yog li ntawd kuj hu ua qhov dub evaporation.
Hais txog qhov no, yuav ua li cas cov dav hlau khiav dim qhov dub?
Raws li qhov dub gobble txog qhov teeb meem nyob rau hauv lawv ib puag ncig, lawv kuj nti tawm muaj zog dav hlau ntawm cov ntshav kub uas muaj electrons thiab positrons, antimatter sib npaug ntawm electrons. Tsuas yog ua ntej cov khoom muaj hmoo tuaj mus txog qhov xwm txheej ntawm lub qab ntug, lossis qhov tsis muaj rov qab los, lawv pib nrawm.
Muaj pes tsawg qhov dub nyob hauv peb lub galaxy?
Judging los ntawm tus cov hnub qub loj txaus los tsim xws li qhov dub Txawm li cas los xij, cov kws tshawb fawb kwv yees tias muaj li ntau raws li kaum lab rau ib billion xws li Cov qhov dub nyob hauv Milky Way ib leeg.

Peb tus yam ntxwv dav dav ntawm cov hlau yog dab tsi?
Peb yam ntxwv ntawm cov hlau yog lawv cov conductivity zoo, malleability, thiab ci iab tsos. Cov hlau yog cov zoo conductors ntawm tshav kub thiab hluav taws xob
Dab tsi yog qhov khiav tawm ntawm lub qhov dub?
Txhawm rau ua qhov no, koj lub pob zeb yuav tsum tau nrawm heev - ntau dua 11 km ib ob. Qhov nrawm no yog hu ua kev khiav tawm nrawm, qhov nrawm ntawm qhov khoom yuav tsum ua tiav txhawm rau txhawm rau kov yeej lub gravitational attraction ntawm lub cev ntuj ceeb tsheej (xws li lub ntiaj teb, lub hnub qub, lossis lub galaxy) thiab khiav mus rau qhov chaw
Dab tsi yog qhov kev teeb tsa hluav taws xob dav dav ntawm SPD thiab F thaiv cov ntsiab lus?
Sau cov txheej txheem hluav taws xob sab nraud ntawm s-, p-, d- thiab f-block ntsiab. Element General sab nrauv hluav taws xob configuration p–block(metals & non metals) ns2np1–6, where n = 2 – 6 d–block(transition elements) (n–1) d1–10 ns0–2, where n = 4 – 7 f -block(internal transition elements) (n–2)f1–14(n–1)d0–10ns2, where n=6–7
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
