Qhov no galaxy yog npe Mrk 820 yog cais raws li ib tug lenticular galaxy - hom S0 ntawm lub Hubble Tuning diav rawg . Cov Hubble Tuning Fork yog siv los faib cov galaxies raws li lawv cov morphology. Elliptical galaxies zoo li du blobs saum ntuj thiab pw ntawm tus kov diav rawg.
Cov lus nug tseem yog, Dab tsi yog Hubble tuning diav rawg?
Cov Hubble Cov kab ke yog ib qho kev faib tawm morphological rau galaxies tsim los ntawm Edwin Hubble xyoo 1926. Nws yog feem ntau hu ua colloquially li Hubble tuning diav rawg daim duab vim yog cov duab nyob rau hauv uas nws yog ib txwm sawv cev.
Kuj Paub, vim li cas Hubble fork daim duab tseem ceeb? Cov Hubble kev faib tawm ntawm galaxies, kuj hu ua 'tuning diav rawg ' daim duab vim nws cov duab, cov chav kawm galaxies raws peb txoj kab tseem ceeb rau hauv: Elliptical galaxies. Kauv galaxies. Barred Kauv Galaxies.
Yog li ntawd, Hubble's tuning fork daim duab ntawm galaxies tiag tiag qhia li cas?
Cov Hubble tuning diav rawg - classification ntawm cov galaxies . Cov daim duab yog roughly muab faib ua ob ntu: elliptical cov galaxies (ellipticals) thiab kauv cov galaxies (spirals). Hubble muab tus lej ellipticals los ntawm xoom mus rau xya, uas qhia lub ellipticity ntawm tus galaxy - "E0" yog yuav luag puag ncig, "E7" yog heev elliptical.
Hubble tsis tu ncua txhais li cas?
Cov Hubble Constant yog chav ntsuas ntsuas siv los piav txog kev nthuav dav ntawm lub qab ntuj khwb. Lub cosmos tau loj dua txij li lub Big Bang ncaws tawm-pib qhov kev loj hlob txog 13.82 billion xyoo dhau los. Lub qab ntuj khwb, qhov tseeb, tau nrawm dua thaum nws loj dua.

P2 2pq thiab q2 sawv cev li cas?
Thaum Hardy-Weinberg equilibrium tau ntsib qhov sib npaug hauv qab no yog qhov tseeb: p2 + 2pq + q2 = 1. Qhov twg p2 sawv cev rau qhov zaus ntawm homozygous dominant genotype, q2 sawv cev qhov zaus ntawm cov genotype recessive thiab 2pq yog qhov zaus ntawm heterozygous
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Ib diav ntawm lub hnub hnyav npaum li cas?
Ib teaspoon ntawm lub hnub ci tseem ceeb yuav hnyav txog 1.6 phaus. Ntawm 27 lab Fahrenheit, nws yog qhov chaw kub tshaj plaws hauv lub hnub ci. Lub siab yog 3.84 trillion psi. Ateaspoonful ntawm lub hnub qub neutron yog qhov zoo tshaj plaws, hnyav txog li ib trillion tons
