3 Te EMF Whakaoho Aukume – Ngā Raru me ngā Otinga

1. Kua whakakapia tētahi koiri ki tētahi atu koiri he rua ngā koropiko he nui ake i ngā koropiko tīmatanga, ā, he pumau tonu te tere o te huringa o te rerenga aukume. Whakatauhia te ōwehenga o te emf whakaoho tīmatanga me te emf whakamutunga.

Mōhiotia:

Ngā koropiko tīmatanga (N) = 1

Ngā koropiko whakamutunga (N) = 2

Ko te tere o te huringa o te rerenga aukume tīmatanga (ΔØ _B / Δt) = te tere o te huringa o te rerenga aukume whakamutunga (ΔØ _B / Δt)

3 Ngā ngaru miihini (Auau Wā Roangaru Te tere o te ngaru) – Ngā Raru me ngā Otinga

1. E rua ngā kōka kei runga i ngā tihi o ngā ngaru . E 20 ngā nekehanga o ngā kōka ki runga, ki raro i runga i te mata o te moana i roto i te 4 hēkona. Mena he 100 cm te tawhiti o ngā kōka e rua, ā, e rua ngā awaawa me te tihi kotahi i waenganui i a rāua, tātaihia te auau o te ngaru me te tere o te ngaru.

Mōhiotia:

Kei ngā tihi o ngā ngaru ngā kōka e rua, ā, kei waenganui i ngā kōka e rua, e rua ngā awaawa me te kotahi te tihi (tirohia te pikitia). Nō reira, e rua ngā roanga ngaru i waenganui i ngā kōka e rua.

Te whakamātautau rua-kōhao a Young – ngā raruraru me ngā otinga

1. ko d te tawhiti i waenganui i ngā kōhao e 2, ko L te tawhiti i waenganui i te kōhao me te mata tirotiro, ko P ₂ te tawhiti i waenganui i te taniko tuarua me te pokapū o te mata. Tātaihia te roanga ngaru o te mārama (1 Å = 10 ^-10 m).

Mōhiotia:

Te tawhiti i waenganui i ngā kōhao e rua (d) = 1 mm = 1 x 10 ^-3 m

Te tawhiti i waenganui i te āputa me te mata tirotiro (L) = 1 m

Te tawhiti i waenganui i te taniko tuarua me te taniko waenga (P ₂ ) = 1 mm = 1 x 10 ^-3 m

1. Ka neke tetahi mea porotaka tuwhera (I = m R ² ) ki te hurihuri me te kore e paheke i runga i te papa piko taratara me te tere tīmatanga o te 10 m/s. Ko te koki teitei o te papa piko he θ me te tan θ = 0.75. Mena ko te whakaterenga ā-papa g = 10 ms ^-2 , ka whakaitihia te tere o te mea ki te 5 ms ^-1 , ko te tawhiti i runga i te papa piko o te mea ko…

Mōhiotia:

Te wā o te korekore o te rango kau (I) = m R ²

Koki teitei = θ , ko te tan θ = 0.75 = 75/100 = opp / adj

Hara θ = opp / hyp = 75/125 = 3/5 = 0.6

Te whakaterenga nā te kaha ā-papa (g) = 10 m/s ²

Te tere tīmatanga (v _o ) = 10 m/s

Te tere whakamutunga (vt ₎ = 5 m/s
