Kusanthula kwa miyeso - mavuto ndi mayankho
1. Kutengera ndi kusanthula kwa miyeso, dziwani miyeso yotsatira ya fizikisi yomwe ili ndi miyeso yofanana.
B. mphamvu ndi kupanikizika
C. mphamvu ndi mphamvu
D. ntchito ndi kutentha
Zodziwika:
Mulingo wa kutalika = muyeso wa m'lifupi = muyeso wa kusuntha = L
Mulingo wa nthawi = T
Kukula kwa kulemera = M
Yankho:
Muyeso wa dera = muyeso wa kutalika x muyeso wa m'lifupi = [L][L] = [L] 2
Mulingo wa liwiro = muyeso wa kusamuka / muyeso wa nthawi = [L] / [T] = [L][T] -1
Muyeso wa kufulumizitsa = muyeso wa liwiro / muyeso wa nthawi = [L][T] -1 / [T] = [L][T] -1 [T] -1 = [L][T] -2
Mulingo wa mphamvu = muyeso wa kulemera x muyeso wa kufulumira = [M][L][T] -2
Muyeso wa ntchito = muyeso wa mphamvu x muyeso wa kusamuka = [M][L][T] -2 [L] = [M][L] 2 [T] -2
Kukula kwa mphamvu = gawo la ntchito / gawo la nthawi = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Mzere wa kupanikizika = gawo la mphamvu / kukula kwa dera = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2
Muyeso wa mphamvu = muyeso wa kulemera x muyeso wa liwiro = [M][L][T] -1
Mulingo wa kutentha = mulingo wa mphamvu = mulingo wa ntchito = [M][L] 2 [T] -2
Yankho lolondola ndi D.
Zindikirani :
Kutentha ndi mphamvu yomwe imayenda chifukwa cha kusiyana kwa kutentha.
Ntchito ndi njira yotumizira mphamvu kudzera mu kusamutsa zinthu.
Kotero, kukula kwa kutentha = kukula kwa mphamvu = kukula kwa ntchito.
2. Kuchuluka kuwiri komwe kuli ndi kuchuluka komweko koma kuli ndi lingaliro losiyana la thupi...
A. Mphamvu ndi mphamvu
B. Mphamvu ndi mphamvu
C. Mphamvu zomwe zingatheke komanso mphamvu ya kayendedwe ka zinthu
D. Mphamvu ndi mphamvu
Yankho:
Gawo la mphamvu yothekera = gawo la mphamvu ya kinetic = gawo la mphamvu = gawo la ntchito.
Ngakhale ili ndi gawo lomwelo , koma mphamvu yomwe ingagwiritsidwe ntchito ndi mphamvu ya kinetic ndi mitundu yosiyanasiyana ya mphamvu.
Yankho lolondola ndi C.
3. Kuchuluka kotsatira komwe kuli ndi mayunitsi omwewo ndi…
A. Mphamvu ndi emf
B. Liwiro ndi kufulumira
C. Ntchito ndi mphamvu
D. Ntchito ndi mphamvu
Yankho:
Ntchito ndi njira yotumizira mphamvu kudzera mu kusamutsa zinthu.
Mphamvu ndi luso logwira ntchito.
Ntchito ndi mphamvu ndi zinthu ziwiri za fizikisi zomwe zili ndi gawo lomwelo.
Yankho lolondola ndi C.
