A. R da S

B. P da R

C. P da Q

D. Q da S

Magani

Ɗalibi P:

Naúrar tsayi ta duniya ita ce mita (m), ba santimita (cm) ba

Kayan aikin auna tsayi shine mai mulki.

Tambayar Ɗalibi:

Naúrar wutar lantarki ta duniya ita ce Ampere (A)

Kayan aikin auna wutar lantarki shine mitar Ampere.

Ɗalibi R:

Naúrar zafin duniya ita ce Kelvin (K)

Kayan aikin auna zafin jiki shine ma'aunin zafi, ba hydrometer ba.

Hydrometer kayan aiki ne da ake amfani da shi don auna yawan ruwa bisa ga manufar buoyancy.

Ɗalibi S:

Nau'in nauyi na duniya (SI) shine kilogram (Kg)

Kayan aikin auna nauyi ma'aunin ma'auni ne

Bayanan da suka dace kuma bisa ga sashin SI (Ƙungiyar Ƙasa da Ƙasa) da ɗalibi Q da S suka nuna.

Amsar da ta dace ita ce D.

2. Nemo daidai dangantakar da ke tsakanin adadi da raka'a.

Magani

Ƙarfi = Mass x Hanzari

Nau'in nauyi na duniya shine kilogiram (kg)

Naúrar gaggawa ta duniya mita a kowace daƙiƙa murabba'i ne (m/s ² )

Raka'ar ƙarfi = kg m/s ² = kg ms ^-2

Matsi = ƙarfi / yanki

Nauyin ƙarfin ƙasa da ƙasa shine kg m/s ²

Sashen ƙasa da ƙasa na yanki shine ^m2

Nau'in matsin lamba = kg /ms ² = kg m ^-1 s ^-2

Makamashi = Aiki

Aiki = ƙarfi x matsar da

Nauyin ƙarfi na ƙasa da ƙasa shine kilogiram mita a kowace daƙiƙa murabba'i (kg m/s ² )

Naúrar ƙaura ta duniya ita ce mita (m)

Nau'in kuzari = naúrar aiki= kg m ² / s ² = kg m ² s ^-2

Iko = Aiki / Lokaci

Naúrar aiki ta duniya ita ce murabba'in mita na kilogiram a kowace daƙiƙa murabba'i (kg m ² / s ² )

Sashen lokaci na duniya shine na biyu (s)

Naúrar wutar lantarki shine kg m ² / s ³ = kg m ² s ^-3

Amsar da ta dace ita ce D.

B. Tsawon, kilogiram, lokaci, yanki, Newton

C. Tsawon, kilogiram, girma, yanki, Joule

D. Tsawon Lokaci, Newton, Lokaci, Ƙara, Mita

Magani:

A = Tsawon

B = Kilogram

C = Lokaci

D = Yanki

E = Kg m/s ² = Newton

4. Kayyade ma'auni da raka'o'i guda biyu na asali a cikin Tsarin Duniya.

A. Tsawon - mita, nauyi - kg da cajin lantarki - coulomb

B. Lokaci - daƙiƙa, zafin jiki - Kelvin, ƙarfin haske - Candela

C. Na biyu - lokaci, mita - tsayi, kg - nauyi

D. nauyi – kg, lokaci – daƙiƙa, Kelvin – zafin jiki

Magani

Adadi na asali da raka'o'in ƙasashen duniya (SI):

Tsawon - mita (m)

Nauyi - kilogiram (kg)

Lokaci - daƙiƙa (s)

Zafin jiki - Kelvin (K)
