Lokacin inertia ga barbashi - matsaloli da mafita
1. Ƙwallaye biyu da aka haɗa da sanda, kamar yadda aka nuna a cikin hoton da ke ƙasa. Yi watsi da sandar taroNauyin ƙwallon P shine gram 600 kuma nauyin ƙwallon Q shine gram 400. Menene lokacin inertia na tsarin game da AB?
An sani:
Axis na juyawa shine AB.
mp = gram 600 = 0.6 kg, mq = gram 400 = 0.4 kg
rp = 20 cm = 0.2 m, rq = 50 cm = 0.5 m
Ana so: Lokacin inertia na tsarin
4 Aiki mai kyau Ƙarfin nauyi Ƙarfin motsi - Matsaloli da Magani
1. Abu mai nauyin kilogiram 5 a tsayin mita 10 a sama da ƙasa. Hanzarta saboda nauyi shine 10 m/s2Menene aikin an yi a kan abin don a motsa shi sama zuwa tsayin mita 15 a sama da ƙasa?
An sani:
Mass na abu (m) = 5 kg
Tsawo (h) = mita 10
Saurin gudu saboda nauyi (g) = 10 m/s2
SE busca: An yi aiki a kan abin don a ɗaga shi sama zuwa tsayin mita 15 a sama da ƙasa.
Lokacin ƙarfi - matsaloli da mafita
1. Idan FR shine ƙarfin F na gaba ɗaya1, F2, da F3, menene girman ƙarfin F2 kuma x?
An sani:
Ƙarfin da aka tara (F)R) = 40 N
Ƙarfi 1 (F)1) = 10 N
Ƙarfi (F)3) = 20 N
SE busca: Girman ƙarfin F2 da kuma nisan x
14 Dokar Boyle Dokar Charles Dokar Gay-Lussac – Matsaloli da Magani
1. Matsin iska na tayoyin mota shine 432 kPa da zafin jiki na 15 oC. Bayan sa'o'i da dama, sai aka sake matsa lamba na iska shine 492 kPa. Idan aka yi watsi da faɗaɗawa, menene da zazzabi iska a cikin tayar?
An sani:
Matsi na farko (P1) = 432 kPa
Matsi na ƙarshe (P2) = 492 kPa
Zafin farko (T1) = 15 oC
SE busca: Zafin ƙarshe (T)2)
Tsarin Carnot - matsaloli da mafita
1 zafi injin ya shanye (Q)1) = Joules 10,000, menene aikin da Injin mota?
Wanda aka sani:
Ƙananan zafin jiki (T)2) = 400 K
Zafin jiki mai yawa (T)1) = 800 K
Shigar da zafi (Q)1) = Joule 10,000
SE busca: Injin Carnot (W) ya yi aiki

Manometer Tube - matsaloli da mafita
1. A bututun manometer yana cike da nau'ikan ruwa guda biyu. yawa na ruwa 1 shine ρ1 = 0.8 g.cm-3, kuma yawan ruwa 2 shine ρ2 = 1 g.cm-3, da tsayi h1 = 10 cm, to menene tsayin h2.
An sani:
Yawan ruwa 1 = 0.8 g.cm-3
Yawan ruwa 2 = 1 g.cm-3
Tsawo 1 = 10 cm
SE busca: Tsawo 2
Makamashin Inji - matsaloli da mafita
Ka'idar makamashin aiki-injini
1. Ma'aunin gogayya ta motsi tsakanin tubali da bene (μ)k) shine 0.5. Menene sauyawa na wani abu(s)? Hanzarta saboda nauyi shine 10 m/s2.
An sani:
Ma'aunin gogayya ta motsi (μ)k) = 0.5
Mass na toshe (m) = 4 kg
Saurin gudu saboda nauyi (g) shine 10 m/s2
Zafin jiki da zafi - matsaloli da mafita
1. A kan ma'aunin zafi na X, wurin daskarewar ruwa a -30o da kuma tafasar ruwa a digiri 90o. 60OX = …… oC.
An sani:
Wurin daskarewar ruwa = -30o
Tafasar ruwan = 90o
Ana so: 60oX = …… oC
