Te Hiko Pūmau me te Utu Hiko: Te Ariā Taketake me ngā Whakamahinga
Pendahuluan
Ko te hiko pūmau me te utu hiko he ariā matua o te ahupūngao e whai wāhi nui ana ki ngā momo āhuatanga taiao me ngā āhuatanga hangarau. Ahakoa he maha ngā wā kāore e kitea, ka kitea ngā pānga o te hiko pūmau i roto i te oranga o ia rā, mai i ngā ru hiko iti e pā ana ki te konganuku tae atu ki ngā mātāpono mahi a ngā mīhini tārua. Ka whakaratohia e tēnei tuhinga he tirohanga whānui mō te hiko pūmau me te utu hiko, e kapi ana i ō rātou whakamāramatanga, ngā mātāpono taketake, me ngā tono.
Te Whakamāramatanga o te Hiko Pūmau
Ko te hiko pūmau te kohikohinga o te utu hiko i runga i te mata o tētahi mea. Ka puta tēnei ina kore e taurite te utu pai me te utu kino i roto i tētahi mea. He rerekē te hiko pūmau i te hiko hihiri (iahiko hiko), arā, ko te rere o te utu hiko mā roto i tētahi kaiārahi hiko.
Utu Hiko
Ko te utu hiko he āhuatanga taketake o ngā matūriki iti-atomika, pērā i ngā porotana me ngā irahiko, e meinga ai rātou kia pāngia e ngā kaha hikohiko. E rua ngā āhua o te utu hiko: he pai me te kino. He utu pai tō ngā porotana, ko ngā irahiko ia he utu kino. Kāore he utu hiko o ngā neutron, arā, ngā matūriki iti-atomika, (koretake).
Ngā Mātāpono Taketake o te Hiko Pūmau
Te Ture a Coulomb
E whakaahua ana te ture a Coulomb i te kaha i waenganui i ngā utu hiko e rua. E ai ki tēnei ture, ko te kaha i waenganui i ngā utu hiko e rua he rite ki te hua o ā rāua utu, ā, he rite whakamuri ki te tapawhā o te tawhiti i waenganui i a rāua. Mā te pāngarau, ko te ture a Coulomb te kī:
\[ F = k_e \frac{|q_1 q_2|}{r^2} \]
kāore i te mana:
– Ko te kaha i waenganui i ngā utu e rua ko \( F \)
– Ko te pūmau Coulomb te \( k_e \) (\(8.987 \times 10^9 \, \text{N m}^2/\text{C}^2\))
– Ko \( q_1 \) me \( q_2 \) ngā rahi o ngā utu
– Ko te \( r \) te tawhiti i waenganui i ngā utu e rua
Te Mātāpono Tiaki Utu
Ko te mātāpono o te tiaki i te utu e kī ana ko te utu hiko katoa i roto i tētahi pūnaha kati ka noho pūmau. Kāore e taea te waihanga, te whakangaro rānei i te utu; ka taea anake te whakawhiti mai i tētahi mea ki tētahi atu. Ko te tikanga o tēnei, ina whakawhitia te utu mai i tētahi mea ki tētahi atu, ka noho tonu te nui o te utu i roto i te pūnaha.
Te Whakaoho Hikohiko
Ko te whakapūngao hikohiko te tukanga e taea ai e te mea kūpapa te whakakahangia me te kore e pā tika ki te mea whakakahangia. Ina whakatatahia te mea whakakahangia ki te mea kūpapa, ka rerekē te tohatoha utu i roto i te mea kūpapa, ka rerekē te utu o te taha e tata ana ki te mea whakakahangia, ā, ka ōrite te utu o te taha kē.
Ngā Āhuatanga Hiko Pūmau i te Oranga o Ia Rā
Ru Hiko
He āhuatanga noa te ru hiko e puta mai ana i te hiko pateko. Hei tauira, ina mirimiri koe i tō waewae ki runga i te whāriki, kātahi ka pā ki te kakau tatau whakarewa, tera pea ka pāngia koe e te ru hiko. Ka puta tēnei nā te mea ka neke ngā irahiko mai i tō tinana ki te kakau tatau, ka hangaia he iahiko hiko rangitahi.
Uira me te Whatitiri
He tauira whakamiharo o te hiko pūmau i roto i te taiao te uira me te whatitiri. Kei roto i ngā kapua tupuhi ngā matūriki hukapapa me te wai e neke ana e tukinga ana tetahi ki tetahi, ka wehea ngā utu. Ka kohia ngā utu kino ki te turanga o te kapua, ko ngā utu pai ia ka kohia ki te tihi. Ina nui te rerekētanga pūmanawa i waenga i te kapua me te whenua, ka peke ngā utu kino i roto i te kapua ki te whenua hei uira, ka whakataurite i te rerekētanga utu.
Ngā Whakamahinga Hiko Pūmau
Kaitārua
Ka whakamahia e ngā mīhini tārua te kaupapa o te hiko pateko hei tārua i ngā tuhinga. Ka utaina te hiko ki te pahu whakaahua i roto i te mīhini tārua. Ina pā te mārama ki te pahu, ka memeha te utu i ngā wāhi e kitea ana, ka waiho he tauira utu e rite ana ki te ahua taketake. Kātahi ka piri te toner utu kino ki ngā wāhi utu pai i runga i te pahu, ka whakawhitia ki te pepa ka whakamahanahia hei hanga i tētahi tārua tuturu.
Whakahaere Parahanga
Ka whakamahia te hiko pūmau hei whakahaere i te parahanga hau mā roto i ngā taputapu e kiia nei ko ngā kaiwhakaoho hiko pūmau. Ka tangohia e ēnei taputapu ngā matūriki parahanga mai i ngā hau putanga ahumahi mā te whakamahi i te utu hiko ki ngā matūriki. Kātahi ka kukumea ngā matūriki kua utua ki ngā pereti kohikohi he utu rerekē, ka tukuna te hau ma ki te āhuarangi.
Te Ārai i ngā Tūponotanga Hiko Pūmau
Te whenua
Ko te whakawhenua he tikanga hei ārai i te kohikohinga o te hiko pateko mā te whakarato i tētahi ara hei rere ai te utu ki te whenua. He mea nui tēnei i roto i ngā taiao ahumahi e taea ai e te hiko pateko te whakaputa i ngā mura kino, inā koa i ngā wāhi he rauemi mura.
Whakamakuku o te Hau
Ka piki ake te tūponotanga o te hanga hiko pateko i te hau maroke. Nō reira, mā te pupuri i ngā taumata haumākū e tika ana ka āwhina i te whakaiti i te hiko pateko. He maha ngā wā ka mahia tēnei i roto i ngā rūma tūmau rorohiko me ngā whare hanga hiko hei ārai i te kino o te hiko pateko.
Te Ine i te Utu me te Hiko Pūmau
Karu hiko
He taputapu māmā noa te karu hiko e whakamahia ana hei kimi i te utu hiko. He tokotoko whakarewa kei runga i te tokotoko ārai me ngā rau koura e rua e iri ana i raro. Ina pāngia te whakarewa e te utu hiko, ka panaia e ngā rau koura tetahi ki tetahi nā te mea ka panaia e ngā utu ōrite tetahi ki tetahi.
Ine hiko
He taputapu matatau ake te ine hikohiko. Ka taea e ia te ine i te hikohiko i runga i te tauine whānui ake, me te tika ake i te karu hikohiko. He maha ngā wā ka whakamahia tēnei taputapu i roto i ngā taiwhanga mō ngā whakamātautau e hiahia ana kia ine tika i te hikohiko.
Whakamutunga
He ariā taketake te hiko pūmau me te utu hiko, ā, he maha ngā whakamahinga o ia rā me te ahumahi. Mai i ngā ru hiko māmā ki ngā āhuatanga taiao whakaharahara pērā i te uira, he mea nui te hiko pūmau i roto i ngā āhuatanga maha o ō tātou oranga. Mā te mārama ki ngā mātāpono taketake me te mahi a te hiko pūmau, ka taea e tātou te whakamahi pai ake i ngā hangarau e whakamahi ana i te hiko pūmau me te ārai i ngā tūponotanga ka pā mai. I te haere tonu o te whanaketanga o te pūtaiao me te hangarau, ka whānui haere, ka auaha ake hoki ngā whakamahinga o te hiko pūmau ā muri ake nei.
