Cov ntsiab lus hauv cov teeb no (10)

A protostar dhau los ua ib lub hnub qub tseem ceeb thaum nws tseem kub. Tshaj kaum lab K. Lub sijhawm ntev nyob ntawm qhov loj ntawm lub hnub qub. Lub hauv paus yog qhov tseem ceeb ntawm lub hnub qub. Nws yog dab tsi pib fusion los ua lub hnub qub tsis tu ncua tom qab ncav cuag qhov kub thiab txias.

Tom qab ntawd, ib tug kuj yuav nug, nyob rau hauv dab tsi point yog lub hnub qub yug?

A hnub qub yog yug ib zaug nws dhau los ua kub txaus rau fusion cov tshuaj tiv thaiv rau qhov chaw ntawm nws cov tub ntxhais. Cov hnub qub siv feem ntau ntawm lawv lub neej raws li cov hnub qub tseem ceeb sib xyaw ua ke hydrogen rau helium hauv lawv qhov chaw. Lub hnub yog ib nrab ntawm nws lub neej raws li ib feem tseem ceeb hnub qub thiab yuav o mus ua ib tug liab giant hnub qub nyob ib ncig ntawm 4.5 billion xyoo.

Tsis tas li ntawd, qhov txawv ntawm protostar thiab lub hnub qub quizlet yog dab tsi? Qhov tseem ceeb qhov sib txawv ntawm ib tug protostar thiab lub hnub qub yog hais tias tom kawg muaj nuclear fusion raws li nws lub zog qhov chaw thiab lub qub tsis. Kev yug ntawm hnub qub yog kev sib ntaus sib tua nruab nrab Lub ntiajteb txawj nqus thiab hluav taws xob siab. Sib nqus teb txhim khu lub cev qhuav dej ntawm huab cua hauv lub hnub qub tsim nrog bipolar ntws.

Tsuas yog li ntawd, ntawm qhov taw tes yog lub hnub qub yug quizlet?

Thaum twg lub hauv paus ntawm ib tug protostar tau mus txog 10 lab K, lub siab nyob rau hauv yog zoo heev uas nuclear fusion ntawm hydrogen pib, thiab ib tug hnub qub yog yug.

Cov huab cua zoo li cas feem ntau yuav yug tau cov hnub qub?

CO and H₂ yog tus feem ntau cov molecules nyob rau hauv interstellar huab cua . Qhov txias txias kuj ua rau gas mus clump rau high densities. Thaum qhov ceev mus txog ib qho chaw, hnub qub daim ntawv. Txij li cov cheeb tsam yog ntom, lawv yog opaque kom pom lub teeb thiab yog hu ua dark nebula.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?

Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?

Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim

Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?

Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%

Qhov txawv ntawm ib tug protostar thiab Nebula yog dab tsi?

Qhov txawv tseem ceeb: Nebula yog huab cua hauv qhov chaw sib sib zog nqus uas muaj roj lossis av / plua plav (xws li huab tsim tom qab lub hnub qub tawg). Ua ntej qhov kawg ua ntu zus, lub hnub qub muaj huab cua ntau ntawm hydrogen, helium thiab hmoov av, uas yog hu ua protostar. Nebula tsim ib tug protostar. Protostar yog qhov ntxov tshaj plaws ntawm lub hnub qub
