6 ʻO ka ʻōnaehana honua o nā ʻāpana Nā prefix ʻāpana - Nā pilikia a me nā hoʻonā
ʻO ka ʻōnaehana honua o nā anakahi
1. ʻO wai o kēia mau anakahi ʻaʻole ia he anakahi o ka lōʻihi
A. Miles
B. Ka wāwae
C. ʻĪniha
D. Knot
Lōlā:
ʻO nā mile, kapuaʻi, a me nā ʻīniha nā anakahi o ka lōʻihi.
ʻO ke knot kahi anakahi o ka wikiwiki a i ʻole ka wikiwiki.
ʻO D ka pane pololei.
2. E hoʻoholo i ke anakahi o ka ʻōnaehana honua o ka modulus o Young
A. kg.m/s 2
B. kg/ms 2
C. m/kg.s 2
D. kg.s 2 /m
ʻIke ʻia:
Anakahi o ka ikaika = kg m/s 2
ʻĀpana o ka ʻāpana = m2
Anakahi o ka lōʻihi = m
Makemake ʻia: Nā ʻāpana o ka ʻōnaehana honua o ka modulus o Young.
Lōlā:
ʻO ka pane pololei ʻo B.
3. ʻO ka nui he anakahi kg.m -1 .s -2 ʻo ia…
A. Kaomi
B. Ikehu
C. Ka ikaika
D. Hoʻolalelale
Lōlā:
Kaomi = Ikaika / ʻĀpana
ʻO ke anakahi honua o ka ikaika he kg m/s 2
ʻO ka ʻāpana honua o ka wahi he m2
ʻO ke anakahi honua o ke kaomi = kg /ms2 = kg m -1 s -2
Ikehu = Hana
Hana = Ikaika x Neʻe ʻana
ʻO ke anakahi honua o ka ikaika he kilokani mika i kekona kuea (kg m/s 2 )
ʻO ka anakahi honua o ka neʻe ʻana he mika (m)
No laila, ʻo ke anakahi ikehu honua = anakahi hana = kg m² / s² = kg m² s -2
Momentum = Mass x velocity
ʻO kg ke anakahi honua o ka nuipa
ʻO m/s ke anakahi honua o ka wikiwiki
No laila, ʻo ke anakahi honua o ka momentum ʻo kg m/s = kg ms -1
Hoʻolalelale = wikiwiki / wā manawa
ʻO ke anakahi honua o ka wikiwiki he mika / kekona (m/s)
ʻO ke anakahi manawa honua he kekona (s)
No laila, ʻo ke anakahi honua o ka wikiwiki ʻo m/s: s = m/sx 1/s = m/s 2 = ms -2
ʻO ka pane pololei ʻo A.
4. ʻO ke anakahi mana honua …
A. kg m 2 s -2
B. kg m 2 s -3
C. g cm 2 s -1
D. g cm s -3
Lōlā:
Mana = Hana / manawa
ʻO ke anakahi hana honua he kilokani mika huinahā per se cond huinahā (kg m² / s² )
ʻO ke anakahi manawa honua he lua ( s)
No laila, ʻo ke anakahi o ka mana he kg m 2 /s 3 = kg m 2 s -3
ʻO ka pane pololei ʻo B.
Nā Prefix Unit
5. ʻO ke kaʻina o ka prefix no nā anakahi mai ka nui a i ka liʻiliʻi i pololei ʻo ia…
A. Mega, tera, nano, pico
B. Giga, Mega, Micro, nano
C. Pico, Nano, Mega, Tera
D. Mega, Tera, Micro, Pico
Lōlā:
ʻO ka pane pololei ʻo B.
6. Ua like ke kenekulia liʻiliʻi me….
A. 1 hola
B. 90 mau minuke
C. 52 minuke
D. 4000 mau kūlana
ʻIke ʻia:
1 lā = 24 hola
1 hola = 60 minuke
1 minuke = 60 kekona
1 lā = 24 x 60 minuke = 1440 mika minuke
1 lā = 1440 x 60 kekona = 86,400 kekona
Makemake ʻia: 1 mi c ro kenekulia = ….. hola = ….. minuke = ….. kekona
Lōlā:
1 maikonona = 10 -6
1 mi c ro kenekulia = 10 -6 kenekulia = 0.000,001 kenekulia
1 kenekulia = 100 makahiki = 100 x 365 makahiki = 36,500 makahiki
1 mi c ro kenekulia = 0.000,001 x 36,500 lā = 0.0365 lā
1 mi c ro kenekulia = 0.0365 x 24 hola = 0.876 hola
1 mi c ro kenekulia = 0.876 x 60 minuke = 52.56 minuke
1 mi c ro kenekulia = 52.56 x 60 kekona = 3153.6 kekona
ʻO C ka pane pololei .
