Kuongorora mativi - matambudziko nemhinduro
1. Zvichibva pakuongorora mativi, sarudza zviyero zvefizikisi zvinotevera zvine zviyero zvakafanana.
B. simba nekumanikidzwa
C. simba uye simba
D. basa nekupisa
Zvinozivikanwa:
Chiyero chehurefu = chiyero chehupamhi = chiyero chekutama = L
Chiyero chenguva = T
Chiyero chehukuru = M
Solution:
Chiyero chenzvimbo = chiyero chehurefu x chiyero chehupamhi = [L][L] = [L] 2
Chiyero chekumhanya = chiyero chekutama / chiyero chenguva = [L] / [T] = [L][T] -1
Chiyero chekumhanyisa = chiyero chekumhanya / chiyero chenguva = [L][T] -1 / [T] = [L][T] -1 [T] -1 = [L][T] -2
Chiyero chesimba = chiyero chehukuru x chiyero chekukurumidzira = [M][L][T] -2
Chiyero chebasa = chiyero chesimba x chiyero chekutama = [M][L][T] -2 [L] = [M][L] 2 [T] -2
Chiyero chesimba = chikamu chebasa / chiyero chenguva = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Dimension of kudzvinyirira = chiyero chesimba / chiyero chenzvimbo = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2
Chiyero chesimba = chiyero chehukuru x chiyero chesimba = [M][L][T] -1
Chiyero chekupisa = chiyero chesimba = chiyero chebasa = [M][L] 2 [T] -2
Mhinduro chaiyo ndiD.
Cherechedza:
Kupisa isimba rinofamba nekuda kwekusiyana kwekupisa.
Basa inzira yekufambisa simba kuburikidza nekufambiswa kwezvinhu.
Saka, chiyero chekupisa = chiyero chesimba = chiyero chebasa.
2. Huwandu huviri hune huwandu hwakafanana asi hune pfungwa yakasiyana yemuviri…
A. Simba uye simba
B. Simba nesimba
C. Simba rinogona kuitika uye simba rekufamba
D. Simba uye simba
Solution:
Chikamu chesimba rinogona kuitika = chikamu chesimba rekinetic = chikamu chesimba = chikamu chebasa.
Kunyangwe iine chinhu chimwe chete , asi simba rinokwanisa kushandiswa uye simba rekinetic imhando dzakasiyana dzesimba.
Mhinduro chaiyo ndeinoti C.
3. Huwandu hunotevera hune mayuniti akafanana ndehwekuti…
A. Simba uye emf
B. Kumhanya uye kukurumidza
C. Basa nesimba
D. Basa nesimba
Solution:
Basa inzira yekufambisa simba kuburikidza nekufambiswa kwezvinhu.
Simba ndiko kugona kuita basa.
Basa nesimba zviyero zviviri zvefizikisi zvine chinhu chimwe chete.
Mhinduro chaiyo ndeinoti C.
