Ib (geographic) meridian (los yog kab longitude ) yog ib nrab ntawm lub voj voog zoo nkauj ntawm lub ntiaj teb saum npoo, txiav los ntawm North Ncej thiab South Ncej, txuas cov ntsiab lus sib npaug longitude , raws li ntsuas hauv angular degrees sab hnub tuaj lossis sab hnub poob ntawm Prime Meridian.
Ib yam li ntawd ib tug yuav nug, dab tsi yog meridians ntawm longitude thiab latitude?
Cov voj voog sib npaug mus rau Equator (kab khiav sab hnub tuaj thiab sab hnub poob) yog qhov sib npaug ntawm latitude . Lawv yog siv los ntsuas cov degrees latitude sab qaum teb los yog sab qab teb ntawm Equator. Meridians ntawm longitude yog kos los ntawm North Ncej mus rau South Ncej thiab yog nyob rau ntawm txoj cai kaum mus rau lub Equator.
Ib tug kuj yuav nug, muaj pes tsawg meridians ntawm longitude? Longitude yog IMAGINARY LINE khiav North Ncej mus rau South Ncej. Txij li thaum lub ntiaj teb yog puag ncig thiab txhua lub voj voog yog 360 degrees, thiab txhua kab ntawm longitude yog 15 degrees deb ntawm Prime Meridian, faib 360 los ntawm 15 thiab saib pes tsawg txoj kab ntawm longitude muaj… 24.
Hais txog qhov no, puas yog meridians thiab longitude tib yam?
Latitude yog ib qho kev ntsuas ntawm qhov deb ntawm sab qaum teb lossis sab qab teb qhov twg yog los ntawm Equator; longitude yog ib qho kev ntsuas ntawm qhov deb ntawm sab hnub tuaj lossis sab hnub poob los ntawm Prime Meridian . Whilst kab (los yog parallels) ntawm latitude tag nrho cov khiav parallel mus rau Equator, kab (los yog meridians ) ntawm longitude tag nrho cov converge ntawm lub ntiaj teb sab qaum teb thiab South Ncej.
Dab tsi yog meridians ntawm lub ntiaj teb?
Meridians Yog Kab ntawm Longitude Meridians yog cov kab uas khiav ntawm North Ncej mus rau South Ncej. Meridians tsis parallel. Lawv sib sau ua ke los yog tuaj ua ke ntawm Cov Nceeg Vaj. Lawv suav los ntawm Prime Meridian (kab 0) rau 180W thiab los ntawm Prime Meridian rau 180e.

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 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
