Feem ntau meteoroids yog ua ntawm silicon thiab oxygen (minerals hu ua silicates) thiab hnyav hlau xws li nickel thiab hlau. Hlau thiab npib tsib xee-hlau meteoroids yog loj thiab ntom, thaum stony meteoroids yog sib dua thiab yooj yim dua.
Tsuas yog li ntawd, dab tsi yog meteors ua los ntawm?
Meteors tsis muaj ntau tshaj li hmoov av thiab dej khov los ntawm txoj kev ntawm comets. Meteorites tuaj yeem yog "stony", ua li ntawm cov zaub mov nplua nuj nyob rau hauv silicon thiab oxygen, "hlau", uas yog feem ntau ntawm hlau thiab npib tsib xee, los yog "stony-hlau", ib tug ua ke ntawm ob.
Ib tug kuj yuav nug, dab tsi yog meteors meteorites thiab meteoroids ua los ntawm? Raws li lub npe implies, hlau meteorites yog muaj li ntawm txog 90 feem pua ntawm hlau; pob zeb meteorites yog ua nce ntawm oxygen, hlau, silicon, magnesium thiab lwm yam khoom. Thiab meteoroids ? Qhov ntawd yog ib lo lus dav dav piav txog cov me me ntawm comets lossis asteroids uas nyob hauv orbit ncig lub hnub.
Kuj paub, qhov twg meteoroids tuaj?
Nyob rau hauv Solar System Feem ntau meteoroids los ntawm lub asteroid txoj siv, tau raug perturbed los ntawm gravitational influences ntawm lub ntiaj chaw, tab sis lwm tus yog hais los ntawm comets, ua rau cov meteor nag. Ib txhia meteoroids yog cov tawg ntawm lub cev xws li Mars lossis peb lub hli, uas tau muab pov rau hauv qhov chaw los ntawm kev cuam tshuam.
3 hom meteoroids yog dab tsi?
Peb Main Hom Meteorites Txawm hais tias muaj ntau cov chav kawm sub, meteorites muab faib ua peb Cov pab pawg tseem ceeb: hlau, pob zeb thiab pob zeb-hlau.

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 txawv ntawm meteors meteorites thiab meteoroids?
Meteoroid: Ib qho me me los ntawm lub hnub qub lossis lub hnub qub ci ntsa iab orbiting lub hnub. Meteor: Lub teeb tshwm sim uas tshwm sim thaum lub meteoroid nkag mus rau hauv lub ntiaj teb huab cua thiab vaporizes; lub hnub qub shooting. Meteorite: Ib lub meteoroid uas muaj sia nyob nws txoj kev hla lub ntiaj teb huab cua thiab tsaws rau ntawm lub ntiaj teb nto
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 hu ua meteoroids?
Ib lub meteoroid (/ˈmiːti?r??d/) yog ib lub pob zeb me me los yog lub cev hlau nyob rau sab nraud. Meteoroids yog qhov me dua li lub hnub qub, thiab qhov loj me los ntawm cov nplej me me mus rau ib-meter-dav khoom. Qhov tshwm sim no hu ua meteor lossis 'shooting star'
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
