6 Sisitimu Yenyika Yose yeZvikamu Mavambo eZvikamu - Matambudziko neMhinduro
The Sisitimu Yenyika Dzese of Units
1. Ndeipi yemayuniti anotevera isiri yuniti yehurefu
A. Makiromita
B. Tsoka
C. Inch
D. Pfundo
Solution:
Makiromita, tsoka, uye mainji mayuniti ekureba.
Pfundo iri iyuniti yekumhanya kana kumhanya.
Mhinduro chaiyo ndiD.
2. Sarudza chikamu chehurongwa hwepasi rose hwe Modulus wechidiki
A. kg.m/s2
B. kg/ms2
C. m/kg.s2
D. kg.s2/m
Zvinozivikanwa:
Chikamu chesimba = kg m/s2
Chikamu chenzvimbo = m2
Chikamu chehurefu = m
Kuda: Chikamu chehurongwa hwepasi rose hwe dikimodulus.
Solution:
Mhinduro chaiyo ndeiyi B.
3. Huwandu hune chikamu kg.m-1.s-2 iri ...
A. Pressure
B. simba
C. tichimhanya
D. kumhanyisa
Solution:
Pressure = simba / nharaunda
Chikamu chesimba repasi rose ndicho kg m/s2
Chikamu chepasi rose chenzvimbo iyi m2
Chikamu chepasi rose chekumanikidzwa = kg / ms2 = kg m-1 s-2
simba = basa
basa = simba x Displacement
Chikamu chesimba repasi rose ndicho mita yekirogiramu pa chikamu chechipiri chakaenzana (kg m/s2)
Chikamu chepasi rose che kudzingiswa is mita (m)
Saka, chikamu chepasi rose chesimba = chikamu chebasa = kg m2/s2 = kg m2 s-2
Kukurumidza = Kurema kumhanya kwa x
Chikamu chepasi rose chehukuru ndeche kg
Chikamu chepasi rose chekukurumidza ndicho m / s
Saka, chikamu chepasi rose che momentum ndicho kg m/s = kg ms-1
kumhanyisa = velocity / nguva yenguva
Chikamu chepasi rose chekukurumidza i meter/chepiri (m / s)
Chikamu chenguva chepasi rose ndechechipiri (S)
Saka, chikamu chepasi rose chekukurumidza chiri m/s : s = m/s x 1/s = m/s2 = ms-2
Mhinduro chaiyo ndeinoti A.
4. Chikamu chepasi rose che simba iri ...
A. kg m2 s-2
B. kg m2 s-3
C. g cm2 s-1
D. g cm s-3
Solution:
simba = basa / nguva
Chikamu chebasa chepasi rose ndeche mita yekirogiramu akaenzana per second yakapetwa kaviri (kg m2/s2)
Chikamu chenguva chepasi rose ndicho semamiriro (S)
Saka, chikamu chesimba ndicho kg m2/s3 = kg m2 s-3
Mhinduro chaiyo ndeiyi B.
Mavambo ekutanga eyuniti
5. Kurongeka kwechivakashure chemayuniti kubva pakukura kusvika kudiki kuti chokwadi ndechekuti…
A. Mega, tera, nano, pico
B. Giga, Mega, Micro, nano
C. Pico, Nano, Mega, Tera
D. Mega, Tera, Micro, Pico
Solution:
Mhinduro chaiyo ndeiyi B.
6. Makore mashoma ekuberekwa akafanana ne….
A. awa imwe chete
B. Maminetsi makumi mapfumbamwe
C. 52 minutes
D. 4000 semamiriro ezvinhu
Zvinozivikanwa:
1 zuva = 24 maawa
1 awa = 60 XNUMX minutes
1 Minutes = 60 masekondi
1 zuva = 24 x gumi maminitsi = 1440 XNUMX minutes
1 zuva= 1440 x gumi masekondi = 86,400 masekondi
Zvaidiwa: 1 micro zana remakore = ….. maawa = ….. maminitsi = ….. masekondi
Solution:
1 micro = 10-6
1 micro zana remakore = 10-6 zana remakore = 0.000,001 emakore
1 zana remakore = 100 makore = 100 x gumi makore= 36,500 makore
1 micro zana remakore = 0.000,001 x gumi mazuva = 0.0365 mazuva
1 micro zana remakore = 0.0365 x gumi maawa = 0.876 maawa
1 micro zana remakore = 0.876 x gumi maminitsi = 52.56 maminitsi
1 micro zana remakore = 52.56 x gumi masekondi = 3153.6 masekondi
Mhinduro chaiyo ndeiyi C.
