Mhando dzemagetsi anochaja - matambudziko nemhinduro
1. Zvichibva pamufananidzo wemagetsi ari pazasi.
Zvinhu A naD zvinochajiwa zvisina kunaka (-), chinhu A chinokwezva chinhu B uye chinodzinga chinhu C, chinhu D chinodzinga E. Sarudza rudzi rwechaji yemagetsi yezvinhu B, C, naE.
A. Zvakanaka, Zvakanaka, Zvakaipa
B. Kuipa, Kuipa, Kunaka
C. Zvakanaka, Zvakaipa, Zvakaipa
D. Zvakanaka, Zvakaipa, Zvakanaka
Solution:
Chaja yemagetsi ine mhando mbiri: positive electric charge uye negative electric charge . Mhando yega yega yechaja inodzinga mhando imwe chete asi inokwezva mhando yakasiyana. Kureva kuti: kusiyana nechaja inokwezva; sekudzinga chaja.
Kana chaji A iri positive charge, chaji A inodzinga chaji B, saka chaji B iri positive charge. Kana chaji P iri negative charge, chaji P inokwezva chaji Q, saka chaji Q iri positive charge.
A imhosva isina kunaka.
D imhosva isina kunaka.
A inokwezva B saka B inomiririra positive charge.
A inodzinga C saka C inenge iri negative charge.
D inodzinga E saka E inenge iri negative charge.
Mhando dzemari B, C, uye E dzakanaka, dzakaipa, dzakaipa.
Mhinduro chaiyo ndeinoti C.

Kana girazi rikakweshwa nesirika, tsananguro chaiyo iri patafura inotevera ndeiyi …
mhinduro
Girazi rine chaji yakanaka, saka kana girazi rikakweshwa nejira rechisiriki maerekitironi anotama kubva pagirazi kuenda kusiriki, saka girazi rine mapurotoni akawanda kupfuura maerekitironi.
Mapurotoni anochajiwa zvakanaka saka girazi rinochajiwa zvakanaka. Asi, sirika ine maerekitironi akawanda kupfuura mapurotoni. Maerekitironi anochajiwa zvakaipa zvekuti jira resirika rinochajiwa zvakaipa.
Mhinduro chaiyo ndeinoti A.
3. Tsvimbo yepurasitiki yakakweshwa nemvere , tsananguro chaiyo ndeiyi… ..
A. Maerekitironi ari mumvere dzemakwai anotamira kupurasitiki, purasitiki inochaja zvisina kunaka
B. Maerekitironi ari mupurasitiki anotamira kumvere dzemakwai, mvere dzemakwai dzinochajwa zvisina kunaka
C. Maerekitironi ari mumvere dzemakwai anochinjana kuita mapurasitiki nemapurotoni, mvere dzemakwai dzinoshaikwa negative charge
D. Maerekitironi ari mupurasitiki anochinjana kuenda kumakushe uye anochinjana nemapurotoni, mapurasitiki anochajiwa zvakanaka.
Solution:
TChaji yemagetsi pamapurasitiki inotenderwa pasi rose sechaji isina kunaka.
Plastiki kana chero chinhu chinoshaikwa negative chaji nekuda kwemaerekitironi akawandisa. Nekuti purasitiki yacho inokweshwa nemvere, zvinogumiswa kuti maerekitironi anochinja kubva pamvere kuenda kupurasitiki.
Mhinduro chaiyo ndeinoti A.
4. Pane bhora reP conductor rine negative charge uye mabhora mana eQ, R, S, T.
B yese P inokwezva Q uye inodzinga S. Bhora Q inodzinga R uye bhora S inodzinga T. Kana bhora P rikaswededzwa pedyo nebhora R uye bhora T saka…..
mhinduro
P inokwezva Q saka Q inova positive charge
P inodzinga S kuitira kuti S ive negative charge
Q inodzinga R saka R inenge iri positive charge
S inodzinga T saka T inenge iri negative charge
Kana bhora P rikaswededzwa pedyo nebhora R , zvinokwezvana.
Kana bhora P rikaswededzwa pedyo nebhora T, zvinodzingana.
Mhinduro chaiyo ndiD.
