Kekahi kaumaha

Paha i nā haumāna, ka poe i ike ole i lohe i ka i kēia pilikia: "O na kanawai hea ka hiki - he nā kilo o fluff paha kilogram pōhaku lepo?". Ka loa 'ike mea mea mea, hoʻowahāwahā i ka waha' nonsense, he nui ka poe e hoʻomau ana ma ka lapuwale loulou. A i loaʻa i ke kaʻana like i loko o ka nohona hana - mea ike ole ia, akā, e hiki ke ea i ka auhau o ke kau paona anaʻikepili o ka a puni mea me ka nānā 'ana ma ka hoʻohālike o ko lākou bulk ano ua, ua hoikeia mai ka manawa o Archimedes. i maopopo i Kekahi Mau ano e ia i ka heluia, o kekahi o ka i ana ai i nā loina, no ka mea hoike, i ke kaumaha a me ka leo. E huli i ka like ana o G ma ka lākiō.

G = P / V, a me ke ana o ka mokuna ma Si - N / cubic mika.

Weight - he ana o ka Honua ka umekaumaha, a me ka hana i ho'ākāka 'umekaumaha no ia kumu i kekahi physical ano o ka waiwai, no ka mea, hilinaʻi nui ma luna o ka wahi o ana. He aha ka mea e e? Hoole i ke kaumaha P - o ka gravitational ikaika ano ke kahua, a ua pili i inertial ano waiwai nuipa a ka m, ma ka hoʻonui o ka noa haule g. Ma ka kekahi lima, g. - vacillates a me ka hilinaʻi nui, me ke komo pu, a me ka mai Leeuwerikplein. No ka Newton ka mua kānāwai P = ka m * g. Mea mau i pololei ia, he mea hiki ke manao nei makou i ka variability o ke kaupaonaʻana i ka mea ia manawa me ka loli ma ka gravitational hoʻonui.

Ka Classic ka wehewehena o: "ke kaʻana like 'ana - o ka lākiō o ke kino ke kaupaona ana i kona leo." Naʻe, i kēia pono io e waiho nō lula 'ka manaʻo pohihihi - pololei ole noi huahelu alakai aku ai i ka huikau o ka manaÿo e pili ana i ke kaumaha a me ke kino ke kaumaha. E like me ua ikeia, nenoaiu nuipa a pa alima (Si) ua like ia 1 kg, a me ka ikaika i loko o kēia 'oihana, e like me Newton ka kānāwai, ka mea, ua ana i loko o newtons, a me ka 1H = 0,102 kg * 9,8 m / kek.. sq.

No ka mea, he nui oaoieei-noi Newton max pa alima o kekahi kaʻao ka, no laila, i hele aku ia i hana i ka hou ana'ōnaehana - gravitational metric kahua. Ua Ua haku o ka poʻe'ē he naehana ana: mika - kgf - kekona. He aha e hāʻawi mai ai? Ua simplifies ka hoʻohana o nā huahelu o ka mana i loko o maoli ke ola no i ka mea laulā olelo o ka papa kaumaha a me kekahi umekaumaha, oa nuʻa i loko o kekahi 'oihana, aka i ka hoʻonui g. mea he ikaika paha negligible.

Ka pono e hoʻohana 'ilepili kaumaha koi i ka mea' ike enehana, ka manao paa o ka impurities i loko o kā lākou 'ole paha porosity.

Ua pono-ike hana no ka hoomaopopo ana i ka hāpana o ke gula, nuʻa gems hale, etc. Ka walaʻauʻana hana o ana i ka hana i ho'ākāka 'umekaumaha ma muli o ka pohupani hale o likeʻole nā kinolau: ke kino kaumaha ua anaia mai ka manawa, a, ma ke kaiapuni i loko o ka wai, kona leo, a ua olelo mai ke koena - pāʻoihana lako a pan. Pakahi aku la ia ka hoʻokō i ka hana o kaʻikepili i loaa i loko o keia ano, ma ka study o ke hooheheeia, a me ko lakou oka. Nō kāu, he priori ike nui ma ke kaupaonaʻana o ka mea hiki ke hooheheeia me ka maikaʻi-? Anoee waiwai. Lākou paha, ka 'me ka hou ana hoʻohālike i loko o na mea he nui i ka mahalo, akā, hoʻomaka i ke ao ana i ka hana i ho'ākāka' umekaumaha.

ʻO ka wai hoʻohana Ua nui ka wai, akā, no ka ana o ka kiʻekiʻe pololei ia 'oi aku ke kiʻekiʻe kumupaʻa o ka mawaho kiko'î - ka mahana a me ka puʻe. I kekahi manawa, no ka mea hoike, ma ka study o Amber no ka hoʻopunipuni hoʻohana kūikawā wai a me kekahi mau 'kaumaha o ka oi ma mua o 2 g. / CC.

I Kekahi Mau umekaumaha ua walaʻauʻanaʻanoʻenehana hehee ai i loko o ka hanalima noi o ʻume mākenēki fluids. Me ka ie-kerosene slurry me ferroporoshkom e leie aku kaʻume mākenēki ke kahua, e hiki wawe ka hana i ka wai a me ka ee iaaanu aey lāʻau a preassigned kekahi umekaumaha. No ka mea, i kekahi kaʻina hana ma luna o ka poʻohiwi enrichment o polymetallic i eliia , a he nui loa nā mea i ka hailona o impurities, a papa i hookaawale ia e ke kiekie o ka flotation bata ma ka ikaika e like me ko lakou poe kanaka kekahi umekaumaha. He hiki ia ia no e like me ka mea e hoohehee environmentally beneficiation enehana - he kukui wā e hiki mai.
