Izinhlobo zamacala kagesi - izinkinga nezixazululo
1. Ngokusekelwe esifanekisweni samanani kagesi angezansi.
Izinto A no-D zishajwa kabi (-), into A idonsela into B futhi ixosha into C, into D ixosha u -E. Nquma uhlobo lweshaja kagesi yezinto B, C, no-E.
A. Okuhle, Okuhle, Okubi
B. Okubi, Okubi, Okuhle
C. Okuhle, Okubi, Okubi
D. Okuhle, Okubi, Okuhle
Isixazululo:
Ishaja kagesi inezinhlobo ezimbili: ishaja kagesi enhle kanye neshaja kagesi engemihle.Uhlobo ngalunye lweshaja luyaxosha uhlobo olufanayo kodwa ludonsela uhlobo oluphambene. Okungukuthi: ngokungafani namacala ayaxosha; njengoba amacala exosha.
Uma ishaja u-A iyishaja elungile, ishaja u-A ixosha ishaja u-B, khona-ke ishaja u-B iyishaja elungile. Uma ishaja u-P iyishaja elungile, ishaja u-P idonsela ishaja u-Q, khona-ke ishaja u-Q iyishaja elungile.
I-A iyinkokhelo engemihle.
I-D iyinkokhelo engemihle.
Ukukhanga B ukuze lokho I-B iyinkokhelo enhle.
U-A uxosha u-C ukuze I-C iyinkokhelo engemihle.
U-D uxosha u-E ukuze I-E iyinkokhelo engemihle.
Izinhlobo zezindleko B, C, kanye no-E zinhle, zimbi, zimbi.
Impendulo efanele ithi C.
2.
Uma ingilazi ihlikihlwa ngesilika, incazelo efanele kuthebula elilandelayo ithi …
Isixazululo
Ingilazi ineshaja enhle, ngakho-ke uma ingilazi ihlikihlwa ngendwangu yesilika khona-ke ama-electron asuka engilazini aye kusilika, ngakho ingilazi inama-proton amaningi kunama-electron.
Ama-proton ashajwa kahle ngakho-ke ingilazi ishajwa kahle. Esikhundleni salokho, isilika inama-electron amaningi kunama-proton. Ama-electron ashajwa kabi ukuze indwangu yesilika ishajwe kabi.
Impendulo eyiyo ngu-A.
3. Induku yepulasitiki ehlikihlwe ngoboya, incazelo efanele ithi…..
A. Eama-lectron eboyeni aya epulasitikini, ipulasitiki ishajeke kabi
B. Eama-lectron epulasitikini aya koboya, uboya bushajwa kabi
C. EAma-lectron kuboya ayashintshana ngepulasitiki nama-proton, uboya bushajelwa kabi
D. EAma-lectron epulasitiki aya kuboya futhi ashintshane nama-proton, amapulasitiki ashajwe kahle
Isixazululo:
TIshaja kagesi kumapulasitiki kuvunyelwene ngayo emhlabeni wonke njengeshaja engemihle.
Ipulasitiki noma noma iyiphi into iba ne-negative charge ngenxa yama-electron amaningi. Ngenxa yokuthi ipulasitiki ihlikihlwa ngoboya, kuphethwa ngokuthi ama-electron asuka kuboya aye kupulasitiki.
Impendulo eyiyo ngu-A.
4. Kukhona umqhubi we-ball P one-negative charge kanye namabhola amane e-Q, R, S, T.
Bkonke u-P kudonsela u-Q futhi kuxosha u-S. Ibhola u-Q uyaxosha u-R kanti ibhola u-S uyaxosha u-T. Uma ibhola u-P kusondezwe eduze ukubhola u-R kanye no-T bese…..
Isixazululo
P ukuheha Q ukuze Q kuyinkokhelo enhle
P iyaxosha S ukuze S kuyicala elibi
Q iyaxosha R ukuze R kuyinkokhelo enhle
S iyaxosha T ukuze T kuyicala elibi
Uma ibhola P kusondela ebholeni R bese bekhangana.
Uma ibhola u-P lisondela ebholeni u-T, bayaxoshana.
Impendulo efanele ithi D.
