Indlela yokubala ubunzima obuthile

Nayiphi na into eneempawu. Yaye ingundoqo yeempawu zanoma yiphina isisindo somzimba, okanye kunoko-isisindo esithile, umlinganiselo wesisindo somzimba othile kunye nomthamo owenziwa ngumzimba. Esi sibonakaliso silandela kwenkcazelo yomatshini yento. Kungenxa yakhe ukuba senza utshintsho kwimida yeenkcazo zekhwalithi. Umxholo kuthi awusasona bunzima be-amorphous, silwela i-center yayo yendalo. Ewe, umzekelo - isistim somhlaba - onke amathambo ayo ahlukeneyo ngokwemigangatho ethile (indlela yokubala ubunzima obuthile-ngaphantsi), kuba banesisindo sabo kunye nomthamo. Ukuba sithatha umhlaba wethu kunye namaqokebhe ayo (i-lithosphere, i-hydrosphere, umoya) ngokwahlukeneyo, kuvela ukuba nabo banabo ubunzima babo, abahlukeneyo kunye nabo.

Ngokufanayo, izixhobo zamakhemikhali ngamnye zinobunzima bawo, kuphela i-athomu. Oku kukho ukubonakalisa ubunzima obuthile. Ngendlela, zikhona izinto ezimbalwa ezingabonakaliswa kwifomu ecocekileyo, kunye nazo zonke ezinye izixhobo, njengomthetho, zizinzile kwaye ziphethe igama lezinto ezilula. Kwi-lithosphere yeplanethi yethu kunezigidi ezingaphezu kwamahlanu, ngasinye sinomsila. Unokubala njani ubukhulu bendawo? Kwaye kunjalo, ngaba le nto ingenziwa?

Kakade. Okwangoku, siza kujonga indlela yokubala ubunzima obuthile. Kungcono ukwenza oku kumzekelo othile, ukuze kuqondwe ngakumbi.

1. Ngokomzekelo, wena uyiNtloko yevenkile yezakhiwo kwaye ufuna ukwazi ukubala ubunzima obuthile bokuthengisa impahla ethile okanye izinto zokusebenza kulo mzekelo. Kufuneka kwaziwe: ubukhulu bokuthengiswa kwemveliso ethile kunye nenani elipheleleyo. Masithi sinakho: uhlobo lomkhiqizo - ibhodi, ingeniso - 15500 (i-rub), ubunzima-81.6%; Uhlobo lomkhiqizo - umthi, ingeniso - 30000 (uhlabe), ubunzima obuthile 15.8%; Uhlobo lomkhiqizo - i-croaker, ingeniso - 190000 (ibhagi), ubunzima obuthile 2.6%. Iyonke: ingeniso - 190,000, kunye nesisindo esithile (isisonke), ngokulandelanayo, i-100%. Ukubala ubunzima bunjani bhodi? Sizahlula ama-155,000 ngo-190,000 kwaye siyanokuphindaphinda ngekhulu. Sifumana i-81.6%. Lo bunzima bebhodi.

2. Ukubala ngokubaluleka komntu othile?

Isisindo esithile kwisizathu esithile sidideka ngokuxininisa, nangona iingcamango zihluke ngokupheleleyo. Ubunzulu obuthile abubhekiseli kwiimpawu ze-physicochemical kwaye uhluke kwixinzelelo, umzekelo, ubunzima besisindo.

2.1.) Ukunyaniseka - ubungakanani bemilinganiselo ukuya kwivolumu, kunye nobukhulu becala - ubungakanani besisindo somthamo, le fomyula ingamelwa ngale ndlela ilandelayo: γ = mg / V. Yaye ukuba ubuninzi bomyinge womzimba onikezelweyo kumqulu walo mzimba, ngoko sibhala ifom yokufumana ubunzima obucacileyo, kule fomu: γ = ρg.

2.2.) Ukuba unqwenela, unokufumana ubunzima obukhulu ngokuvakala kunye nobunzima, okanye ngeendlela zokulinga, ngokuthelekisa iimpawu zengcinezelo. Apha i-equation hydrostatics iya kusetyenziswa: P = Po + γh. Kodwa le ndlela isebenza kuphela kwimeko apho zonke iinani ezilinganisiweyo ziyaziwa ngaphandle ngaphandle. Kule meko, umgaqo wokufumana ubunzima obuthile uya kuthatha ifom elandelayo: γ = P-Po / h. Esi sihlandlo sisoloko sisetyenziselwa ukuchaza iinqanawa zokuthetha kunye nesenzo sabo. Ngokwe siseko sedatha yokulinga, isiphetho siyilungileyo: yonke into ekhoyo kwimikhumbi yokuthetha iya kuba nokuphakama kwayo kunye nokwenyuka kwayo kwiindonga zesitya apho le nto ikhona khona.

2.3.) Ukuze ubale (ukubala) ubunzima obucacileyo, sinokusebenzisa enye ifomu (i-Archimedes force force). Uyakhumbula izifundo zesikolo kwi-physics? Mhlawumbi, bambalwa kuphela abaza kuphendula kwi-affirmative. Ngoko ke, sihlaziye inkumbulo: amandla ase-Archimedes-sila aphelisa . Masithi sithwele imithwalo enomlinganiselo othile (siya kukhetha lo mthwalo njenge "m"), egcina amanzi. Kulo mzuzwana, umthwalo uthinteka ngamabutho amabini, okokuqala ngumbutho onamandla, kwaye okwesibini yi-Archimedes (ibutho liyaphakamisa, kwaye isalathiso sibuyela kumvini mg). Kule ndlela, amandla ka-Archimedes abonakala ngathi: Fapx = ρgV. Ukwazi ukuba i-ρg ilingana nobunzima bomzimba obuninzi, sifumana ukulingana okulandelayo: Fapx = yV, kwaye ukusuka kulo sifumana: y = Fapx / V.

Ngaba kunzima? Emva koko yenza lula: ukuze ubale ubunzima obucacileyo, hlukanisa ubunzima bubungakanani.
