Falanqaynta cabbirka - dhibaatooyinka iyo xalalka
1. Iyada oo ku saleysan falanqaynta cabbirka, go'aami cabbirrada fiisigiska ee soo socda ee leh cabbirro isku mid ah.
B. awood iyo cadaadis
C. xoog iyo xawli
D. shaqada iyo kuleylka
La yaqaan:
Cabbirka dhererka = cabbirka ballaca = cabbirka barokaca = L
Cabbirka waqtiga = T
Cabbirka cufka = M
Xalka:
Cabbirka bedka = cabbirka dhererka x cabbirka ballaca = [L][L] = [L]2
Cabbirka xawaaraha = cabbirka barakac / cabbirka waqtiga = [L] / [T] = [L][T]-1
Cabbirka dardargelinta = cabbirka xawaaraha / cabbirka waqtiga = [L][T]-1 / [T] = [L][T]-1[T]-1 = [L][T]-2
Cabbirka xoogga = cabbirka cufka x cabbirka dardargelinta = [M][L][T]-2
Cabbirka shaqada = cabbirka xoogga x cabbirka barokaca = [M][L][T]-2 [L] = [M][L]2[T]-2
Cabbirka awoodda = cabbirka shaqada / cabbirka waqtiga = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Qiyaasta cadaadiska = cabbirka xoogga / cabbirka bedka = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2
aragti xawaaraha = cabbirka cufka x cabbirka xawaaraha = [M][L][T]-1
Cabbirka kulaylka = cabbirka tamarta = cabbirka shaqada = [M][L]2[T]-2
Jawaabta saxda ah waa D.
Fiiro gaar ah:
Heat waa tamar dhaqaaqda oo ay ugu wacan tahay farqiga heerkulka.
Shaqadu waa habka wareejinta tamarta iyada oo loo marayo barakicinta walxaha.
Markaa, cabbirka kulaylka = cabbirka tamarta = cabbirka shaqada.
2. Laba tiro oo leh tiro isku mid ah laakiin leh fikrad jireed oo ka duwan…
A. Xoogga iyo xawaaraha
B. Tamarta iyo xoogga
C. Tamarta suurtagalka ah iyo tamarta dhaqdhaqaaqa
D. Tamarta iyo xawaaraha
Xalka:
Cutubka tamarta suurtagalka ah = cutubka tamar kuleylka = cutubyada tamarta = cutubyada shaqada.
Ainkastoo ay leedahay awoode cutubyo, laakiin tamarta suurtagalka ah iyo tamarta dhaqdhaqaaqa waa noocyo kala duwan oo tamar ah.
Jawaabta saxda ah waa C.
3. Tirada soo socota ee leh halbeegyo isku mid ah waa…
A. Xoogga iyo emf
B. Xawaaraha iyo dardargelinta
C. Shaqada iyo tamarta
D. Shaqada iyo awoodda
Xalka:
Shaqadu waa habka wareejinta tamarta iyada oo loo marayo barakicinta walxaha.
Tamartu waa awoodda lagu qaban karo shaqada.
Shaqada iyo tamartu waa laba tiro oo fiisigis ah oo leh halbeeg isku mid ah.
Jawaabta saxda ah waa C.
