3 Tusaalooyin oo ah Su'aalaha Xawaaraha Celceliska ah
1. Subax kasta, Hadi wuxuu had iyo jeer ku ordaa meel lagu cabbiro 100 m x 400 m 12 jeer 1 saac gudaheed. Xawaaraha celceliska celceliska xawaaraha dhaqdhaqaaqa Hadi waa...
A. 0 km/saacaddii iyo 12 km/saacaddii
B. 0 km/saacaddii iyo 6 km/saacaddii
C. 6 km/saacaddii iyo 12 km/saacaddii
D. 6 km/saacaddii iyo 6 km/saacaddii
E. 12 km/saacaddii iyo 12 km/saacaddii
Dood
Waa la ogyahay in:
Dhererka garoonka = 400 mitir
Ballaca goobta = 100 mitir
Wareegga beerta = (2 x 400 mitir) + (2 x 100 mitir) = 800 mitir + 200 mitir = 1000 mitir
Masaafada Hadi = 12 x 1000 mitir = 12.000 mitir = 12 kiiloomitir
La weydiiyay: Xawaaraha celceliska iyo xawaaraha celceliska
Jawaab:
Xawaaraha celceliska:
Hadi wuxuu garoonka ku wareegay 12 jeer, taasoo la macno ah in ka dib markii uu orday, Hadi uu ku soo laabtay booskiisii hore, sidaas darteed barakaciisii wuxuu ahaa eber. Maadaama barakacu ahaa eber, celceliska xawaaraha wuxuu ahaa eber.
Xawaaraha celceliska:
Xawaaraha celceliska = wadarta masaafada la safray / wadarta waqtiga = 12 km / 1 saac = 12 km/saacaddii
Jawaabta saxda ah waa A.
2. Garaafka dhinaca ku yaal wuxuu muujinayaa xiriirka ka dhexeeya masaafada (s) iyo waqtiga (t) ee shay socda. Haddii s uu yahay m, iyo t uu yahay ilbiriqsiyo, markaa celceliska xawaaraha shayga waa...
A. 0,60 ms -1
B. 1,67 ms -1
C. 2,50 ms -1
D. 3,0 ms -1
E. 4,6 ms -1
Dood
Xawaaraha celceliska = Wadarta masaafada la safray / Wadarta waqtiga u dhexeeya
Xawaaraha celceliska = 15 mitir / 6 ilbiriqsi = 2,5 mitir/ilbiriqsi
Jawaabta saxda ah waa C.
3. Walax ayaa u dhaqaaqda waqooyi barta bilowga (0,0) una socota barta P (2,4) 3 ilbiriqsi gudahood. Walaxdu waxay markaa u jeedsataa bari 2 ilbiriqsi ilaa ay gaarto barta Q (10,10). Celceliska xawaaraha marka walaxdu ka dhaqaaqdo P una gudubto Q wuxuu la mid yahay….
A. 2 ms-1
B. 5 ms-1
C. 7 ms-1
D. 10 ms-1
E. 12 ms-1
Dood
Barakaca PQ:
Xawaaraha celceliska:
Jawaabta saxda ah waa B.
4. Haddii celceliska xawaaraha shay uu eber yahay, markaas...
A. walxaha ku socda xawaare joogto ah
B. Masaafada la safray waxay la mid tahay eber
C. walxaha oo horay iyo gadaal u socda
D. barokaca shaygu wuxuu la mid yahay eber
E. celceliska xawaaraha shaygu wuxuu la mid yahay eber
Dood
Qaacidada xawaaraha celceliska = wadarta barakicinta / wadarta waqtiga u dhaxaysa
Haddii celceliska xawaaraha shay uu eber yahay, markaas kala-guurka shaygu waa eber.
Jawaabta saxda ah waa D.
