Cov equator yog 0 degrees latitude, thiab lub ntsiab meridian yog 0 degrees longitude. Cov equator yog qhov chaw nruab nrab ntawm North Ncej thiab South Ncej. Nws khiav los ntawm sab rau sab nyob rau hauv nruab nrab ntawm lub ntiaj teb los ntawm ib feem ntawm South America, Africa, thiab Asia.
Ib yam li ib tug yuav nug, puas yog txoj kab nruab nrab khiav sab hnub tuaj mus rau sab hnub poob?
Cov kab latitude khiav sab hnub tuaj thiab sab hnub poob thiab ntsuas sab qaum teb thiab sab qab teb; longitude kab khiav sab qaum teb thiab sab qab teb thiab ntsuas sab hnub tuaj thiab sab hnub poob . Cov equator yog 0 degree latitude. Qhov kev xav txog kab no, uas khiav los ntawm thaj chaw ntawm South America, Africa, thiab Asia, yog qhov chaw ib nrab ntawm North Ncej thiab South Ncej.
Ib yam li ntawd, cov kab twg ntsuas sab qaum teb thiab sab qab teb ntawm txoj kab nruab nrab thiab khiav sab hnub tuaj mus rau sab hnub poob? Cov kab kev xav uas ncig lub ntiaj teb nyob rau sab hnub tuaj-sab hnub poob yog hu ua kab ntawm latitude (los yog parallels, raws li lawv yog parallel rau tus kab zauv). Lawv siv los ntsuas qhov deb ntawm sab qaum teb thiab sab qab teb ntawm txoj kab nruab nrab. Cov kab ncig lub ntiaj teb nyob rau sab qaum teb-sab qab teb yog hu ua kab ntawm longitude (los yog meridians ).
Ntxiv mus, yuav ua li cas cov kab latitude khiav nyob rau hauv kev sib raug zoo rau lub equator?
Kab ntawm latitude (parallels) khiav sab hnub tuaj-sab hnub poob thoob plaws ntiaj teb thiab yog siv los ntsuas qhov deb NORTH thiab SOUTH ntawm tus equator . Txij li thaum equator yog 0?, latitude ntawm tus ncej qaum teb, 1/4 ntawm txoj kev ncig lub ntiaj teb mus rau sab qaum teb, yuav ua 90n. Qhov no yog qhov siab tshaj latitude ua tau.
Lub hom phiaj ua haujlwm li cas?
Cov Equator thiab Prime Meridian yog lub voj voog uas ncab thoob plaws ntiaj teb. Cov Equator cais Northern thiab Southern Hemispheres. Cov Equator yog ntawm 0° latitude. Lub Prime Meridian cais sab hnub tuaj thiab sab hnub poob Hemispheres.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Cov kab hluav taws xob hluav taws xob pib thiab xaus qhov twg?
Cov cai hauv qab no siv rau cov kab hluav taws xob: Cov kab pib thiab xaus nkaus xwb (pib ntawm + nqi, xaus ntawm - nqi) lossis ntawm Infinity. Cov kab yog nyob ze ua ke qhov twg lub teb muaj zog dua. Cov nqi loj dua muaj ntau kab kab pib lossis xaus rau lawv
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
