Sisitimu yepasi rose yemayuniti Zvikamu zveUnit - Matambudziko neMhinduro

6 Sisitimu Yenyika Yose yeZvikamu Mavambo eZvikamu - Matambudziko neMhinduro

Sisitimu Yenyika Yose yeZvikamu

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 hweYoung's modulus

A. kg.m/s ²

B. kg/ms ²

C. m/kg.s ²

D. kg.s ² /m

Zvinozivikanwa:

Chikamu chesimba = kg m/s ²

Chikamu chenzvimbo = ^m2

Chikamu chehurefu = m

Zvinodiwa: Zvikamu zvehurongwa hwepasi rose hweYoung 's modulus.

Solution:

Mhinduro chaiyo ndeiyi B.

3. Huwandu hune yuniti kg.m ^-1 .s ^-2 iri…

A. Kumanikidzwa

B. Simba

C. Kufambira mberi

D. Kukurumidzisa

Solution:

Kumanikidzwa = Simba / Nzvimbo

Chikamu chesimba repasi rose i kg m/s ²

Chikamu chepasi rose chenzvimbo ^iyi m2

Chikamu chepasi rose chekumanikidzwa = kg /ms ² = kg m ^-1 s ^-2

Simba = Basa

Basa = Simba x Kudzingwa

Chikamu chesimba chepasi rose ikirogiramu mita pasekondi yakaenzana nesikweya (kg m/s ² )

Chikamu chepasi rose chekutama imita (m)

Saka, chikamu chepasi rose chesimba = chikamu chebasa = kg m ² /s ² = kg m ² s ^-2

Kumhanya = Kurema x kumhanya

Chikamu chehuremu hwepasi rose i kg

Chiyero chepasi rose chekukurumidza i m/s

Saka, chikamu chepasi rose che momentum i kg m/s = kg ms ^-1

Kukurumidzisa = kumhanya / nguva pakati

Chiyero chepasi rose chekukurumidza imita / sekondi (m/s)

Chikamu chenguva chepasi rose ndechechipiri (s)

Saka, chikamu chepasi rose chekumhanyisa ndeche m/s : s = m/sx 1/s = m/s ² = ms ^-2

Mhinduro chaiyo ndeinoti A.

4. Chikamu chepasi rose chesimba ndicho…

A. kg m ² s ^-2

B. kg m ² s ^-3

C. g cm ² s ^-1

D. g cm s ^-3

Solution:

Simba = Basa / nguva

Chikamu chebasa chepasi rose ikirogiramu mita yakaenzana nemativi mana ( kg m ² /s ² )

Chikamu chenguva chepasi rose chinonzi se cond (s)

Saka, chikamu chesimba i kg m ² /s ³ = kg m ² s ^-3

Mhinduro chaiyo ndeiyi B.

Mavambo ekutanga eyuniti

5. Kurongeka kwe prefix yemayuniti kubva pahombe kusvika padiki ndiko kwakarurama ndekwekuti …

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 madiki ekuberekwa akafanana ne….

A. awa imwe chete

B. Maminetsi makumi mapfumbamwe

C. 52 m maminiti

D. 4000 se conds

Zvinozivikanwa:

Zuva rimwe = maawa makumi maviri nemana

Awa imwe = maminetsi makumi matanhatu

Miniti imwe = masekondi makumi matanhatu

Zuva rimwe = maminetsi makumi maviri nemana x makumi matanhatu = maminetsi zana nemakumi mana nemakumi mana

Zuva rimwe = 1440 x 60 masekondi = 86,400 masekondi

Zvaidiwa: 1 mi c ro century = …….. maawa = …….. maminitsi = …….. masekondi

Solution:

1 maikironi = 10 ^-6

1 mi c ro zana remakore = 10 ^-6 mazana emakore = 0.000,001 mazana emakore

Zana remakore rekutanga = makore zana = makore zana x makumi matanhatu nemashanu = makore zviuru makumi matatu nezvitanhatu nemazana mashanu

1 mi c ro century = 0.000,001 x mazuva 36,500 = mazuva 0.0365

1 mi c ro century = 0.0365 x maawa makumi maviri nemana = maawa 0.876

1 mi c ro century = 0.876 x 60 maminitsi = 52.56 maminitsi

1 mi c ro century = 52.56 x 60 seconds = 3153.6 seconds

Mhinduro chaiyo ndiC.
