6 Dongosolo Lapadziko Lonse la Mayunitsi Ma Prefixes a Mayunitsi - Mavuto ndi Mayankho

Dongosolo Lapadziko Lonse la Mayunitsi

1. Ndi iti mwa mayunitsi otsatirawa yomwe si yautali?

A. Makilomita

B. Phazi

C. Inchi

D. Mfundo

Yankho:

Makilomita, mapazi, ndi mainchesi ndi mayunitsi a kutalika.

Fundo ndi gawo la liwiro kapena liwiro.

Yankho lolondola ndi D.

2. Dziwani gawo la dongosolo lapadziko lonse la Young's modulus

A. kg.m/s ²

B. kg/ms ²

C. m/kg.s ²

D. kg.s ² /m

Zodziwika:

Chigawo cha mphamvu = kg m/s ²

Chigawo cha dera = m ²

Chigawo cha kutalika = m

Kufunidwa: Magawo a dongosolo lapadziko lonse la Young 's modulus.

Yankho:

Yankho lolondola ndi B.

3. Kuchuluka kwake kuli ndi gawo kg.m ^-1 .s ^-2 ndi…

A. Kupanikizika

B. Mphamvu

C. Mphamvu

D. Kuthamanga

Yankho:

Kupanikizika = Mphamvu / Malo

Chigawo cha mphamvu yapadziko lonse lapansi ndi kg m/s ²

Gawo lapadziko lonse lapansi la dera ^ndi m2

Gawo la mayiko la kupanikizika = kg /ms ² = kg m ^-1 s ^-2

Mphamvu = Ntchito

Ntchito = Mphamvu x Kusamutsidwa

Chigawo cha mphamvu yapadziko lonse lapansi ndi kilogalamu mita pa sekondi imodzi, sikweya (kg m/s ² )

Gawo lapadziko lonse lapansi la kusamuka ndi mita (m)

Kotero, gawo la mphamvu lapadziko lonse lapansi = gawo la ntchito = kg m ² /s ² = kg m ² s ^-2

Momentum = Kulemera x liwiro

Chigawo cha kulemera chapadziko lonse lapansi ndi kg

Chigawo cha liwiro lapadziko lonse lapansi ndi m/s

Kotero, gawo la mayiko lonse la mphamvu ndi kg m/s = kg ms ^-1

Kuthamanga = liwiro / nthawi yopuma

Chigawo cha liwiro lapadziko lonse lapansi ndi mita / sekondi (m/s)

Gawo la nthawi yapadziko lonse lapansi ndi lachiwiri (s)

Chifukwa chake, gawo lapadziko lonse la kufulumizitsa ndi m/s : s = m/sx 1/s = m/s ² = ms ^-2

Yankho lolondola ndi A.

4. Gawo la mphamvu padziko lonse lapansi ndi…

A. kg m ² s ^-2

B. kg m ² s ^-3

C. g cm ² s ^-1

D. g cm s ^-3

Yankho:

Mphamvu = Ntchito / nthawi

Gawo la ntchito yapadziko lonse lapansi ndi kilogalamu mita imodzi yozungulira pa se cond yozungulira (kg m ² /s ² )

Gawo la nthawi yapadziko lonse lapansi ndi se cond (s)

Kotero, gawo la mphamvu ndi kg m ² /s ³ = kg m ² s ^-3

Yankho lolondola ndi B.

Ma Prefixes a Unit

5. Ndondomeko yolondola ya mayunitsi kuyambira akulu mpaka ang'onoang'ono ndi …

A. Mega, tera, nano, pico

B. Giga, Mega, Micro, nano

C. Pico, Nano, Mega, Tera

D. Mega, Tera, Micro, Pico

Yankho:

Yankho lolondola ndi B.

6. Zaka zana zazing'ono ndi zofanana ndi….

A. Ola limodzi

B. Mphindi 90

C. 52 m inutes

D. 4000 se conds

Zodziwika:

Tsiku limodzi = maola 24

Ola limodzi = mphindi 60

Mphindi imodzi = masekondi 60

Tsiku limodzi = mphindi 24 x 60 = mphindi 1440

Tsiku limodzi = masekondi 1440 x 60 = masekondi 86,400

Ankafuna: 1 mi c ro century = ….. maola = ….. mphindi = ….. masekondi

Yankho:

Mikroni imodzi = 10 ^-6

1 mi c ro century = 10 ^-6 century = 0.000,001 century

Zaka zana limodzi = zaka 100 = zaka 100 x 365 = zaka 36,500

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

1 mi c ro century = 0.0365 x maola 24 = maola 0.876

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

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

Yankho lolondola ndi C.
