Teb. Qhov chaw ntawm cov ncej ntawm li hlau nplaum tuaj yeem txiav txim siab los ntawm kev ncua nws dawb. Ib qho yooj yim tshem tawm bar hlau nplaum ib txwm taw rau hauv sab qaum teb − sab qab teb kev taw qhia. Qhov kawg uas taw tes rau sab qaum teb kev taw qhia yog tus ncej qaum teb ntawm tus hlau nplaum thaum kawg uas taw tes rau sab qab teb kev taw qhia yog sab qab teb ncej ntawm tus hlau nplaum.
Hauv qhov no, lub compass siv los nrhiav kev taw qhia li cas?
A compass yog ib qho instrument uas yog siv los nrhiav tus kev taw qhia ntawm ib tug magnetic teb. A compass muaj ib tug me me hlau koob uas yog magnetized nws tus kheej thiab uas yog dawb los tig rau hauv ib qho twg kev taw qhia . Cov compass koob dlhos nrog lub ntiaj teb magnetic teb kev taw qhia thiab taw tes rau sab qaum teb-sab qab teb.
Ib tug kuj nug, koj yuav nrhiav tau tus ncej ntawm horseshoe hlau nplaum li cas? Coj ib lub bar hlau nplaum thiab coj nws N ncej nyob ze ib ncej ntawm nees khau hlau nplaum . Yog tias muaj kev tawm tsam ntawm A thiab N ces A yog North ncej thiab B yog South ncej ntawm nees khau hlau nplaum . Yog tias B thiab N tawm tsam ib leeg, B yog sab qaum teb thiab A yog sab qab teb nees khau hlau nplaum.
Tsis tas li ntawd, bar hlau nplaum nyob qhov twg?
SOLUTION: Ncej ntawm a bar hlau nplaum yog nyob ntawm ob qhov kawg ntawm bar hlau nplaum . Sab qaum teb (N) thiab Sab Qab Teb (S) ntawm a bar hlau nplaum muaj nyob rau hauv daim duab. A bar hlau nplaum tsis muaj cov cim qhia txog nws cov ncej.
Koj txiav txim siab li cas?
Yog li, yog tias koj paub lub sijhawm ntawm hnub, koj tuaj yeem paub koj li kev taw qhia . Yog hais tias nws yog yav tsaus ntuj, piv txwv li, thiab lub hnub yog teem, lub kev taw qhia ntawm qhov twg lub hnub yog West, thiab opposite ntawm lub kev taw qhia Lub hnub yog East. Nyob ntawm qhov koj tab tom ntsib, koj tuaj yeem ua tau txiav txim North thiab South los ntawm cov ntaub ntawv no.

Vim li cas kev taw qhia ntawm cov kab hlau nplaum yog los ntawm sab qaum teb mus rau sab qab teb?
Thaum nws los txog rau hlau nplaum, opposites nyiam. Qhov tseeb no txhais tau hais tias sab qaum teb kawg ntawm cov hlau nplaum nyob rau hauv ib lub compass yog attracted rau sab qab teb magnetic ncej, uas nyob ze rau thaj tsam qaum teb ncej. Cov kab hlau nplaum sab nraud ntawm cov hlau nplaum ruaj khov ib txwm khiav ntawm sab qaum teb sib nqus ncej mus rau sab qab teb magnetic ncej
Lub teb chaws twg nyob ntawm latitude 10 degrees sab qaum teb?

Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Kuv yuav nrhiav tau cov ncej teeb nyob qhov twg?
