Lissafi na amfani da makamashin lantarki ta amfani da kayan aikin lantarki - matsaloli da mafita
1. A cikin gida, akwai fitilu 5 da ake amfani da su Watt 25 a kowace rana awanni 14 a rana, akwai firiji mai Watt 200 da ake amfani da shi awanni 24 a rana, da kuma famfon ruwa mai Watt 125 da ake amfani da shi awanni 8 a rana. Nawa ne makamashin lantarki da ake amfani da shi tsawon wata guda (kwana 30)?
An sani:
Ƙarfin fitila = 5(25) = Watt 125 kuma lokacin amfani = awanni 14 x 30 = awanni 420
Ƙarfin firiji = Watts 200 kuma lokacin amfani = Awa 24 x 30 = Awa 720
Ƙarfin famfon ruwa = Watts 125 da lokacin amfani = awanni 8 x 30 = awanni 240

1. Yaro mai gani a kunne zai iya karanta littafi a kusa da mita 1. Domin karatu a nisan karatu na yau da kullun na 25 cm, tabbatar da cewa yaron yana amfani da ƙarfin ruwan tabarau.
Magani:
Yaron yana fama da hangen nesa , inda wurin da idonsa yake kusa da shi mita 1 ko 100 cm. Wurin da idon yake kusa da shi na yau da kullun shine santimita 25. Ana iya daidaita idon ta hanyar amfani da ruwan tabarau mai lanƙwasa.
Makamashin Kinetic - Matsaloli da mafita
1. Motoci biyu suna da nauyin iri ɗaya , suna motsawa tare da kuzarin motsi daban-daban. Ƙarfin motsi na motar farko ya ninka ƙarfin motsi na motar ta biyu sau 9. Kwatancen saurin mota na farko da mota ta biyu shine…..
An sani:
Nauyin mota A (m A ) = m
Nauyin mota B (m B ) = m
Ƙarfin motsi na mota B (K E B ) = K E
Ƙarfin motsi na mota A (K E A ) = 9 K E
