Muaj teeb meem ntau dhau ua rau lub hnub qub tawg, ua rau a supernova . Raws li lub hnub qub khiav tawm ntawm cov roj nuclear, qee qhov ntawm nws cov huab cua ntws mus rau hauv nws cov tub ntxhais. Thaum kawg, qhov tseem ceeb yog hnyav heev uas nws tsis tuaj yeem tiv taus nws tus kheej gravitationalforce. Cov tub ntxhais hluas tawg, uas ua rau muaj qhov tawg loj heev supernova.

Ib yam li ntawd, tib neeg nug, ua li cas thaum lub sijhawm supernova?

Qhov no tawg tshwm sim vim qhov chaw, orcore, ntawm lub hnub qub poob qis dua ib pliag. Cov txheej txheej sab nrauv ntawm lub hnub qub tau tawg tawm hauv qhov tawg, tawm hauv ib qho kev cog lus ntawm lub hnub qub tom qab lub supernova . Cov shocks thiab cov khoom uas ya tawm ntawm lub supernova tuaj yeem ua rau lub hnub qub tshiab.

Yuav ua li cas supernovae tshwm sim? Qhov nruab nrab, a supernova yuav tshwm sim txog ib zaug txhua 50 xyoo hauv lub galaxy qhov loj ntawm Milky Way. Lwm txoj hauv kev, lub hnub qub tawg txhua ob lossis ntau qhov chaw hauv lub qab ntuj khwb, thiab qee qhov ntawm lub ntiaj teb tsis deb dhau.

Hauv qhov no, qhov kev piav qhia yooj yim supernova yog dab tsi?

A supernova yog thaum lub hnub qub loj heev tawg. Nws tshwm sim thaum nws cov fusion nuclear tsis tuaj yeem tuav lub coreaginst nws tus kheej lub ntiajteb txawj nqus. Lub hauv paus tawg, thiab tawg. Lawv muab lub zog sib npaug rau tag nrho lub neej ntawm lub hnub ci zoo li hnub ci.

Lub supernova loj npaum li cas?

Cov hnub qub no xaus lawv cov evolution nyob rau hauv loj heev cosmicexplosions hu ua supernovae . Thaum twg supernovae tawg, lawv jettison teeb meem rau hauv qhov chaw ntawm qee qhov 9,000 txog 25,000miles (15,000 txog 40,000 kilometers) ib ob.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?

Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration

Dab tsi yog qhov nro ntawm qhov chaw thiab dab tsi ua rau nws?

Nto nro yog qhov nyiam ntawm cov dej ntws mus rau hauv qhov tsawg kawg nkaus qhov chaw ua tau. Ntawm cov kua-cua sib cuam tshuam, qhov nro ntawm qhov chaw tshwm sim los ntawm kev nyiam ntawm cov kua molecules ntau dua rau ib leeg (vim kev sib koom ua ke) dua li cov molecules hauv huab cua (vim adhesion)

Lub pulsar yog dab tsi thiab dab tsi ua rau nws mem tes?

Pulsars yog rotating neutron hnub qub pom tias muaj pulses ntawm hluav taws xob ntawm lub sijhawm tsis tu ncua uas feem ntau yog li ntawm milliseconds mus rau vib nas this. Pulsars muaj cov hlau nplaum muaj zog heev uas funnels dav hlau ntawm cov khoom tawm raws li ob tus ncej sib nqus. Cov khoom nrawm no tsim cov kab teeb muaj zog heev

Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?

Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
