Nā kaapuni uila me nā resistors ma ke kū'ē like a me ke kū'ē kūloko - nā pilikia a me nā hoʻonā
1. Ma muli o ke kiʻi ma lalo nei, inā he 24 Volts ke kumu o ka ikaika electromotive (emf), e hoʻoholo uila uila I.
ʻIke ʻia:
Kumu o ka emf = 24 Volt
Ke kū'ē kūloko (r) = 2 Ohms
Kū'ē 40 ʻOhm, 20 ʻOhm, a me 20 ʻOhm.
Ka helu ʻana o ka hoʻohana ʻana i ka ikehu uila e nā mea hana uila - nā pilikia a me nā hoʻonā
1. I loko o kahi hale, aia he 5 mau kukui 25 Watt i hoʻohana ʻia no 14 mau hola i ka lā, kahi pahu hau 200 Watt i hoʻohana ʻia no 24 mau hola i ka lā, a me kahi pamu wai 125 Watt i hoʻohana ʻia no 8 mau hola i ka lā. ʻEhia ka nui ka ikehu uila hoʻohana ʻia no hoʻokahi mahina (30 mau lā)?
ʻIke ʻia:
Mana o ke kukui = 5(25) = 125 Watt a me ka manawa hoʻohana = 14 hola x 30 = 420 hola
Mana o ka paila = 200 Watts a me ka manawa hoʻohana = 24 mau hola x 30 = 720 mau hola
Ka mana o ka pamu wai = 125 Watts a me ka manawa hoʻohana = 8 hola x 30 = 240 hola
Nā ʻano o nā uku uila - nā pilikia a me nā hoʻonā
1. Ma muli o ke kiʻi o ka nā uku uila ma lalo nei.
Ua hoʻopiʻi maikaʻi ʻole ʻia nā mea A a me D (-), ʻo ka mea A ,ʻo mea B a me kipaku aku mea C, mea D kipaku aku E. E hoʻoholo ʻano o ka hoʻouku uila o nā mea B, C, a me E.
A. Maikaʻi, Maikaʻi, Maikaʻi ʻole
B. Maikaʻi ʻole, Maikaʻi ʻole, Maikaʻi
C. Maikaʻi, Maikaʻi ʻole, Maikaʻi ʻole
D. Maikaʻi, Maikaʻi ʻole, Maikaʻi
6 Mīkini maʻalahi (Lever mokulele inclined) - Nā pilikia a me nā hoʻonā
1.
ʻO wai ka mokulele hilig i loaʻa ka pono mechanical like?
ʻIke kokoke a me ka ʻike mamao - nā pilikia a me nā hoʻonā
1. He keiki me nʻike pepeiao hiki ke heluhelu i kahi puke ma kahi kokoke i 1 mika. I mea e heluhelu ai ma kahi heluhelu maʻamau mamao he 25 kenimika, e hoʻoholo i ka mana o ke aniani e pono ai ke keiki e hoʻohana.
Lōlā:
Ua ʻeha ke keiki ʻike maka, kahi o ke kiko kokoke o kona mau maka he 1 mika a i ʻole 100 kenimika. ʻO ke kiko kokoke o ka maka maʻamau he 25 kenimika. Hiki ke hoʻololi ʻia ka maka e ka aniani ʻōpuʻu.
Ikehu Kinetic - nā pilikia a me nā hoʻonā
1. Ua like nā kaʻa ʻelua nuipa, e neʻe ana me ka ikehu kinetic ʻokoʻa. ikehu kinetic ʻO ka ikehu kinetic o ke kaʻa mua he 9 manawa o ka ikehu kinetic o ke kaʻa ʻelua. ʻO ka hoʻohālikelike wikiwiki o ke kaʻa mua me ke kaʻa ʻelua he…..
ʻIke ʻia:
Ka Mass o ke kaʻa A (mA) = m
Ka nuipa o ke kaʻa B (mB) = m
ʻO ka ikehu kinetic o ke kaʻa B (KEB) = KE
ʻO ka ikehu kinetic o ke kaʻa A (KEA) = 9 KE
Ka wikiwiki o nā nalu transverse - nā pilikia a me nā hoʻonā
1.
Inā he 2 kekona ka manawa e pono ai e hele mai A a i B, e hoʻoholo i ka wikiwiki o nalu transverse.
ʻIke ʻia:
Ka mamao AB = 6 mikas
manawa wā mawaena AB = 2 kekona
Makemake: Ka wikiwiki o ka nalu transverse
Radioactivity - nā pilikia a me nā hoʻonā
1. Ma muli o ke kiʻi ma lalo nei, pāhanahana ka hana ma hope o ka palaho no 13.86 mau hola he ...
ʻIke ʻia:
Hapa-ola (T1/2) = 6.93 hola
Ka manawa holo (t) = 13.86 hola
Makemake: hana radioactive
ʻO ka wili micrometer - nā pilikia a me nā hoʻonā
1. Ke ana ʻana o ke anawaena o ka uea me kahi micrometer ʻo 2.48mm. ʻO ke kiʻi e pili ana i ka hopena ana ʻo…
