6 Siostam Eadar-nàiseanta nan Aonadan Ro-leasachain Aonad – Duilgheadasan agus Fuasglaidhean

Siostam Eadar-nàiseanta nan Aonadan

1. Dè de na h - aonadan a leanas nach eil na aonad faid?

A. Miles

B. Cois

C. Òirch

D. Snaidhm

fuasgladh:

Is e mìltean, troighean, agus òirlich aonadan faid.

'S e aonad astair no luaths a th' anns an snaidhm.

Is e D am freagairt cheart.

2. Obraich a-mach aonad siostam eadar-nàiseanta modúl Young

A. kg.m/ ^s²

B. kg/ ^ms²

C. m/ ^kg.s²

D. kg.s² ^/ m

Aithnichte:

Aonad feachd = kg m/ ^s²

Aonad farsaingeachd = ^m²

Aonad faid = m

A dhìth: Na h-aonadan den t-siostam eadar-nàiseanta de mhodal Young.

fuasgladh:

Is e am freagairt cheart B.

3. Tha aonad kg.m ^-1 .s ^-2 aig meud…

A. Brùthadh

B. Lùth

C. Gluasad

D. Luathachadh

fuasgladh:

Brùthadh = Feachd / Raon

Is e kg m/s² ^an aonad eadar-nàiseanta feachd

^{Is e} m² an aonad eadar-nàiseanta de raon

An aonad eadar-nàiseanta cuideam = kg /ms² ⁼ kg m ^-1 s ^-2

Lùth = Obair

Obair = Feachd x Gluasad

Is e an aonad eadar-nàiseanta feachd cileagram meatair gach diog ceàrnagach (kg m/ ^s² )

Is e meatair (m) an aonad eadar-nàiseanta airson gluasad

Mar sin, an aonad eadar-nàiseanta lùtha = aonad obrach = kg m ² /s ² = kg m ² s ^-2

Momentum = Tomad x astar

Is e kg an aonad eadar-nàiseanta de mhais

Is e m/s an aonad eadar-nàiseanta astair

Mar sin, is e kg m/s = kg ms ^{-1 an aonad eadar-nàiseanta de ghluasad}

Luathachadh = astar / eadar-ama ùine

Is e meatair / diog (m/s) an aonad eadar-nàiseanta astair

Is e an aonad ùine eadar-nàiseanta diog (diog)

Mar sin, is e m/s an aonad luathachaidh eadar-nàiseanta : s = m/sx 1/s = m/ ^s2 = ms ^-2

Is e A am freagairt cheart.

4. Is e an aonad cumhachd eadar-nàiseanta …

A. kg m² ^s - ²

B. kg m² ^s - ³

C. g cm² ^s - ¹

D. g cm s ^-3

fuasgladh:

Cumhachd = Obair / ùine

Is e an aonad obrach eadar-nàiseanta cileagram meatair ceàrnagach gach diog ceàrnagach (kg ^m² / ^s² )

Is e diogan an aonad ùine eadar- nàiseanta

Mar sin, is e an aonad cumhachd kg m ² /s ³ = kg m ² s ^-3

Is e am freagairt cheart B.

Ro-leasachain Aonaid

5. Is e an òrdugh ceart airson ro-leasachan airson aonadan bho mhòr gu beag …

A. Mega, tera, nano, pico

B. Giga, Mega, Micro, nano

C. Pico, Nano, Mega, Tera

D. Mega, Tera, Micro, Pico

fuasgladh:

Is e am freagairt cheart B.

6. Tha meanbh-linn mar an ceudna ri….

A. 1 uair a thìde

B. 90 mionaid

C. 52 mionaid

D. 4000 diogan cond

Aithnichte:

1 latha = 24 uair a thìde

1 uair = 60 mionaid

1 mionaid = 60 diogan

1 latha = 24 x 60 mionaid = 1440 mionaid

1 latha = 1440 x 60 diogan = 86,400 diogan

A dhìth: 1 mìle c ro linn = ….. uairean = ….. mionaidean = ….. diogan

fuasgladh:

1 micron = ^10-6

1 mìle c ro linn = 10 ^-6 linntean = 0.000,001 linntean

1 linn = 100 bliadhna = 100 x 365 bliadhna = 36,500 bliadhna

1 mìle c ro linn = 0.000,001 x 36,500 latha = 0.0365 latha

1 mìle c ro linn = 0.0365 x 24 uairean = 0.876 uairean

1 mìle c ro linn = 0.876 x 60 mionaid = 52.56 mionaid

1 mìle c ro linn = 52.56 x 60 diogan = 3153.6 diogan

Is e C am freagairt cheart .
