Nrog rau kwv yees ob lub ntiaj teb nyob rau nruab nrab rau txhua lub hnub qub hauv qhov no galaxy , yielding kwv yees li 400 billion planets, lub muaj peev xwm nrhiav tau ib lub hnub qub qhov system uas yog analogous rau peb yog heev ze 100%.
Yog li ntawd, yuav ua li cas thiaj nrhiav tau cov kab ke zoo sib xws hauv Milky Way galaxy?
Tam sim no, cov lus teb: Cov muaj peev xwm yog 100%. Ntxiv dua thiab, saib qhov FACTS. Tus naj npawb ntawm infinite cov galaxies thiab pawg ua cov muaj peev xwm ntawm lub ntiaj teb zoo li lub ntiaj teb thiab a zoo li Milky Way Galaxy loj dua.
Ib tug kuj yuav nug, pes tsawg lub hnub ci nyob hauv Milky Way galaxy? Txog tam sim no, astronomers tau pom ntau dua 500 hnub ci tshuab thiab nrhiav tau cov tshiab txhua xyoo. Muab ntau npaum li cas lawv tau pom nyob rau hauv peb lub zej zog ntawm cov Milky Way galaxy, cov kws tshawb fawb kwv yees tias tej zaum yuav muaj kaum tawm billions ntawm hnub ci tshuab nyob rau hauv peb galaxy, tej zaum txawm li ntau li 100 billion.
Hais txog qhov no, puas yog lub hnub ci tshwj xeeb lossis tsis tshua muaj peev xwm nrhiav tau qhov zoo sib xws hauv Milky Way galaxy?
Teb cov lus nug: Yog, lub hnub ci system yog tshwj xeeb hauv nws tus kheej txoj kev , tab sis peb ua tau nrhiav 'yuav luag' zoo sib xws systems nyob hauv lub qab ntuj khwb.
Hnub ci system nyob qhov twg hauv Milky Way?
Cov Hnub Ci System : Cov Hnub Ci System (thiab Lub Ntiaj Teb) nyob li ntawm 25,000 lub teeb xyoo mus rau qhov chaw galactic thiab 25,000 lub teeb xyoo deb ntawm ntug. Yog li qhov yooj yim, yog tias koj xav txog qhov Milky Way Raws li cov ntaub ntawv loj, peb yuav yog qhov chaw uas kwv yees ib nrab ntawm qhov nruab nrab thiab ntug.

Peb lub hnub nyob qhov twg hauv Milky Way galaxy quizlet?
Nyob rau hauv lub Milky Way Galaxy, peb lub hnub nyob: nyob rau hauv lub Galactic halo
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Puas muaj peev xwm equilibrium zoo ib yam li so muaj peev xwm?
Qhov sib txawv ntawm daim nyias nyias muaj peev xwm thiab qhov muaj peev xwm sib npaug (-142 mV) sawv cev rau lub zog hluav taws xob hluav taws xob uas tsav Na + mus rau hauv lub xovtooj ntawm lub peev xwm so membrane. Thaum so, txawm li cas los xij, qhov permeability ntawm daim nyias nyias mus rau Na + tsawg heev kom tsuas yog me me Na + xau rau hauv lub cell
