Chikamu cheInternational chakarurama chakaratidzwa nemudzidzi …
A. R naS
B. P naR
C. P na Q
D. Q na S
mhinduro
Mudzidzi P:
Chiyero chehurefu chepasi rose imita (m), kwete masendimita (cm)
Chishandiso chekuyera hurefu ndicho chinotonga.
Mubvunzo weMudzidzi:
Chiyero chepasi rose chemagetsi emagetsi chinonzi Ampere (A)
Chishandiso chekuyera magetsi emagetsi iAmpere meter.
Mudzidzi R:
Chikamu chetembiricha chepasi rose ndiKelvin (K)
Chishandiso chekuyera tembiricha ithermometer, kwete hydrometer.
Hydrometer chishandiso chinoshandiswa kuyera huwandu hwemvura zvichibva papfungwa yekuti mvura inoyerera sei.
Mudzidzi S:
Chiyero chepasi rose (SI) chehuremu ikirogiramu (Kg)
Chishandiso chekuyera huremu chiyereso chekuenzanisa
Ruzivo rwakarurama uye rwakavakirwa pachikamu cheSI (Chikamu Chenyika Dzose) chinoratidzwa nemudzidzi Q na S.
Mhinduro chaiyo ndiD.
2. Tsvaga hukama hwakakodzera pakati pehuwandu nemayuniti.
mhinduro
Simba = Kurema x Kukurumidzisa
Chiyero chehuremu hwepasi rose chinonzi kilogram (kg)
Chikamu chepasi rose chekumhanyisa (acceleration unit) i square metres pa sekondi (m/s 2 )
Chikamu chesimba = kg m/s 2 = kg ms -2
Kumanikidzwa = simba / nzvimbo
Chikamu chesimba repasi rose i kg m/s 2
Chikamu chepasi rose chenzvimbo iyi m2
Chikamu chekumanikidzwa = kg /ms 2 = kg m -1 s -2
Simba = Basa
Basa = simba x kusuduruka
Chikamu chesimba chepasi rose ikirogiramu mita pasekondi yakaenzana nesikweya (kg m/s 2 )
Chikamu chepasi rose chekutama imita (m)
Chikamu chesimba = chikamu chebasa= kg m 2 /s 2 = kg m 2 s -2
Simba = Basa / nguva
Chikamu chebasa chepasi rose chinonzi kilogram mita yakaenzana nesekondi imwe neimwe yakaenzana nesekondi imwe neimwe (kg m 2 /s 2 )
Chikamu chenguva chepasi rose ndechechipiri (s)
Chikamu chesimba i kg m 2 /s 3 = kg m 2 s -3
Mhinduro chaiyo ndiD.
3.
Zvichibva patafura iri pamusoro, tsvaga A, B, C, D, naE.
A. Vhoriyamu, kilogiramu, tembiricha, nzvimbo, mita
B. Kureba, kilogiramu, nguva, nzvimbo, Newton
C. Kureba, kilogiramu, vhoriyamu, nzvimbo, Joule
D. Kureba, Newton, nguva, vhoriyamu, mita
Solution:
A = Kureba
B = Kilogiramu
C = Nguva
D = Nzvimbo
E = Kg m/s 2 = Newton
Mhinduro chaiyo ndeiyi B.
4. Sarudza peya yehuwandu hwekutanga nemayuniti muInternational System.
A. Kureba– mita, huremu – kg uye chaji yemagetsi—coulomb
B. Nguva – yechipiri, tembiricha – Kelvin, kupenya kwakasimba—Candela
C. Chechipiri - nguva, mita - kureba, kg - huremu
D. huremu – kg, nguva – sekondi, Kelvin – tembiricha
mhinduro
Huwandu hwepakutanga uye mayuniti epasi rose (SI):
Kureba - mita (m)
Misa - kilogiramu (kg)
Nguva - yechipiri (s)
Tembiricha - Kelvin (K)
Kupenya kwakasimba—Candela
Mhinduro chaiyo ndeiyi B.
5.
Huwandu hwakakodzera uye mayuniti zvichibva paInternational System of Units (SI) inoratidzwa nenhamba…
A. 1 ne3
B. 1 na4
C. 1, 2, uye 3
D. 1, 3, uye 4
mhinduro
Huwandu uye mayuniti eInternational System (SI):
(1) Tembiricha - Kelvin
(2) Huremu - Kilogiramu
(3) Nguva - Yechipiri
(4) Kureba - Meta
Mhinduro chaiyo ndiD.
