Haya, twende na maswali haya ya fizikia.
9. a) Describe the pattern observed. (1 mark)
Mchoro unaonyesha mistari ya uga wa sumaku (magnetic field lines) inayotoka kwenye ncha ya kaskazini (red) na kuingia kwenye ncha ya kusini (blue) ya sumaku. Mistari hii huunda mizunguko iliyofungwa nje ya sumaku na huwa minene zaidi karibu na ncha za sumaku.
9. b) State TWO properties of magnets. (2 marks)
Hapa kuna sifa mbili za sumaku: • Sumaku huvutia vitu vilivyotengenezwa kwa chuma, nikeli, na kobalti. • Sumaku huwa na ncha mbili, kaskazini na kusini, ambazo haziwezi kutenganishwa. Ncha zinazofanana hupingana, na ncha tofauti huvutiana.
10. a) Identify TWO components shown. (2 marks)
Kulingana na picha: Q: High voltage transmission lines (Mistari ya kusambaza umeme wa volti ya juu) R: Power station (Kituo cha kuzalisha umeme)
10. b) State ONE importance of power transmission. (1 mark)
Umuhimu mmoja wa usambazaji wa umeme ni: • Kupeleka umeme kutoka vituo vya kuzalisha umeme hadi maeneo ya matumizi kama vile nyumba, viwanda, na biashara, hata kama viko mbali.
