A. h – g – i – h – g
B. g – a – g – a – h
C. g – i – h – g – i
D. i – g – h – g – i
Kōrero
Kotahi te wiri o te pōro ina wehe atu i tōna tūranga taketake, kātahi ka hoki anō ki tōna tūranga taketake. Hei tauira, ka tīmata te pōro ki te neke mai i i, kātahi ki g, kātahi ki h, kātahi ka hoki ki g, kātahi ka hoki ki tōna tūranga taketake i i, ko te raupapa o te nekehanga pōro ko i – g – h – g – i. Hei tauira rānei, ka tīmata te pōro ki te neke mai i g, kātahi ki i, kātahi ka hoki ki g, kātahi ki h, kātahi ka hoki ki g, ko te raupapa o te nekehanga pōro ko g – i – g – h – g.
Ko te whakautu tika ko D.

C. 200 N
D. 1000 N
Kōrero
Taumaha kawenga = 100 Newton. Hei hiki i te kawenga, me whakamahi te kaha iti rawa o te 100 Newton.
Ko te whakautu tika ko B.
9 Ngā tauira pātai mō ngā panonitanga o ngā āhua pūngao
1. I roto i te rino hiko, ka puta he panoni...
A. te pūngao wera ki te pūngao hiko
B. te pūngao hiko ki te pūngao wera
C. te pūngao hiko ki te pūngao matū
D. pūngao matū ki te pūngao hiko
Kōrero
Ka taea te whakamahi i te rino hiko mēnā he hiko kei roto. I muri i te hono atu ki tētahi pūtake hiko, ka wera te pereti rino kei raro i te rino. Nō reira, ka taea te whakatau ko te rino hiko ka huri i te kaha hiko hei kaha wera.
6 Ngā tauira pātai mō ngā rahinga me ngā waeine
1. Kei roto i te rōpū o ngā rahinga taketake ngā mea e whai ake nei...
A. tere, papatipu, me te mātotoru
B. te kaha o te au, te roa, me te pāmahana
C. horahanga, tere, me te wā
D. te rōrahi, te roa, me te wā
Kōrero
Ko ngā rahinga taketake ko te roa, te papatipu, te wā, te pāmahana, te iahiko hiko, te kaha kanapa, me te nui o te matū. Haunga ēnei rahinga e whitu, ko ētahi atu rahinga he rahinga whakaputa.
Ko te whakautu tika ko B.
Rauemi kaha hiko (EMF) raupapa me te whakarara
Mena e rua, neke atu rānei i te rua ngā pūtake hiko (emf) e honoa ana pērā i te pikitia i te taha, ka honoa raupapa te emf.
Ko te pūtake ngaohiko whakakapinga ( ε ) ko:
ε = ε 1 + ε 2 + ε n
Ko te ātete i roto i te whakakapinga (r) ko:
E ai ki te Ture Tuarua a Kirchhoff, ko te tapeke o ngā huringa o te pūmanawa hiko huri noa i tētahi ara iahiko kati he kore. Ko te Ture Tuarua a Kirchhoff e ahu mai ana i te ture tiaki pūngao, e kī ana he mea tiaki te pūngao.
Hei mārama ake i tēnei, whakaarohia he hiko e neke ana i roto i tētahi ara iahiko kati, pērā i te ahua kei te taha matau. Ina utu hiko haere mā roto i tētahi ātete hiko (R), ka heke te kaha hiko nā te mea ka pau i roto i te ātete. Mēnā ka haere te utu hiko mā roto i tētahi atu ātete hiko, ka heke anō te kaha hiko nā te mea ka pau anō i roto i taua ātete. Hei tāpiri, ina haere te utu hiko mā roto i tētahi pūtake ngaohiko hiko mai i te kaha iti ki te kaha teitei, ka piki ake te kaha hiko. Ina hoki ki tōna pūwāhi taketake, pūngao pūmanawa hiko pērā anō i mua, arā, ko te huringa o te pūngao pūmanawa hiko he kore. Ina whakamahia te ture tuarua a Kirchhoff ki tētahi ara iahiko hiko, ka whakamahia e tātou te huringa o te ngaohiko hiko, ehara i te huringa o te pūngao pūmanawa hiko.
