4 mau laʻana o nā paipu ʻano U i hoʻopili ʻia i nā ipu
1. Ua hoʻopiha ʻia nā ipu ʻelua ʻo A a me B me nā wai o nā ʻano like ʻole, e like me ka mea i hōʻike ʻia ma ke kiʻi. Inā like ke kaomi ma lalo o A me 4/5 o ke kaomi ma lalo o B a ʻo ka nui o ka wai A = 1000 kg m –3 , a laila ʻo ka nui o ka wai ma B he …
A. 1250 kg m-3
B. 2500 kg m –3
C. 3000 kg m –3
D. 4000 kg m –3
E. 5000 kg m –3
Pahana
Ua ʻike ʻia:
Kaomi ma ke kumu o A ( PA ) = 4/5 manawa o ke kaomi ma ke kumu o B (4/5 P B )
Ka nui o ka wai A ( ρ A ) = 1000 kg m –3
Nīnau: Ka nui o ka wai B ( ρ B )
Pane:
ʻO ke ʻano hana no ke kaomi hydrostatic o ka wai A ʻo P A = ρ A gh A
ʻO ke ʻano hana no ke kaomi hydrostatic o ka wai B ʻo P B = ρ B gh B
Kaomi ma ke kumu o A = 4/5 manawa o ke kaomi ma ke kumu o B:
ʻO ke kiʻekiʻe o ka wai ma A = ke kiʻekiʻe o ka wai ma B i hoʻopau ʻia ai ʻo h A a me h B mai ka hoohalike.
Ua like ka wikiwiki ma muli o ke koʻikoʻi g no laila ua hoʻopau ʻia ia mai ka hoohalike.
5 (ρ A ) = 4 (ρ B )
5 (1000) = 4 (ρ B )
ρ B = 5000/4
ρ B = 1250
ʻO ka nui o ka wai ma B he 1250 kg m –3
ʻO A ka pane pololei.
2. Ua piha kahi ʻōmole U meme ʻelua mau wai like ʻole e like me ka mea i hōʻike ʻia ma ke kiʻi aʻe! Inā ʻo ka nui o ka nui ρ1 = 0,8 g.cm-3, ρ2 = 1 g.cm-3, a me h1 = 10 kenimika, a laila ke kiʻekiʻe h2 ʻo ia….
A. 5 kenimika
B. 6 kenimika
C. 7 kenimika
D. 8 kenimika
E. 10 kenimika
Pahana
Ua ʻike ʻia:
Ka nui o ka paʻa 1 = 0,8 g.cm -3
Ka nui o ka paʻa 2 = 1 g.cm -3
Kiʻekiʻe 1 = 10 kenimika
Nīnau ʻia: Kiʻekiʻe 2
Pane:
ʻO D ka pane pololei.
3.
Ua hoʻopiha ʻia kahi ʻōmole U me ʻelua mau wai like ʻole e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei! Inā ʻo ka nui o ka nui p1 = 0,8 g.cm-3, p2 = 1 g.cm-3, a me h1 = 10 kenimika, a laila ke kiʻekiʻe h2 ʻo ia….
A. 5 kenimika
B. 6 kenimika
C. 7 kenimika
D. 8 kenimika
E. 10 kenimika
Pahana
Ua ʻike ʻia:
Ka nui o ka paʻa 1 = 0,8 g.cm-3
Ka nui o ka paʻa 2 = 1 g.cm-3
Kiʻekiʻe 1 = 10 kenimika
Nīnau ʻia: Kiʻekiʻe 2
Pane:
ʻO D ka pane pololei.
4. 
E hoʻolohe i ke kiʻi aʻe:
Ua hoʻopiha mua ʻia kahi ʻōmole U me ka wai me ka nui o 1000 kg.m-3 A laila, ninini ʻia ka ʻaila kuke i loko o kekahi o nā paipu i mea e like ai ke kūlana paʻa me ke kiʻi. Inā he 8 kenimika ke kiʻekiʻe o ke kolamu ʻaila a he 5 kenimika ke kolamu wai, ʻo ka nui o ka ʻaila kuke….
A. 520 kg.m-3
B. 525 kg.m-3
C. 600 kg.m-3
D. 625 kg.m-3
E. 720 kg.m-3
Pahana
Ua ʻike ʻia:
Ka nui o ka wai = 1000 kg.m-3
Ke kiʻekiʻe o ka wai = 5 kenimika
Ke kiʻekiʻe o ka ʻaila kuke = 8 kenimika
Nīnau: Ka nui o ka ʻaila kuke
Pane:
ʻO D ka pane pololei.
