Lokacin inertia ga barbashi - matsaloli da mafita
1. Ƙwallo biyu da aka haɗa da sanda, kamar yadda aka nuna a cikin hoton da ke ƙasa. Yi watsi da nauyin sandar . Nauyin 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.
m p = gram 600 = 0.6 kg, m q = gram 400 = 0.4 kg
r p = 20 cm = 0.2 m, r q = 50 cm = 0.5 m
Ana so: Lokacin rashin ƙarfin 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. Saurin gudu saboda nauyi shine mita 10/s 2. Menene aikin da ake yi akan abu don motsa shi sama zuwa tsayin mita 15 a sama da ƙasa?
An sani:
Nauyin abu (m) = 5 kg
Tsawo (h) = mita 10
Saurin gudu saboda nauyi (g) = 10 m/s 2
Ana nema: 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 F R shine ƙarfin F 1 , F 2 , da F 3 , menene girman ƙarfin F 2 da x?
An sani:
Ƙarfin da aka tara (F)R) = 40 N
Ƙarfi 1 (F 1 ) = 10 N
Ƙarfi (F3 ) = 20 N
Ana so: Girman ƙarfin F 2 da nisan x
14 Dokar Boyle Dokar Charles Dokar Gay-Lussac – Matsaloli da Magani
1. Matsin iska na tayar mota shine 432 kPa tare da zafin jiki na 1 5 oC . Bayan awanni da yawa, matsin iska shine 492 kPa. Idan aka yi watsi da faɗaɗawa , menene zafin iska a cikin tayar?
An sani:
Matsi na farko (P1 ) = 432 kPa
Matsi na ƙarshe (P2 ) = 492 kPa
Zafin farko (T1 ) = 15 oC
Ana so: Zafin ƙarshe ( T2 )
Tsarin Carnot - matsaloli da mafita
1. Idan injin ya sha zafi (Q 1 ) = Joules 10,000, menene aikin injin Carnot yake yi?
Wanda aka sani:
Ƙananan zafin jiki (T2 ) = 400 K
Zafin jiki mai yawa (T 1 ) = 800 K
Shigar da zafi (Q1 ) = Joules 10,000
Ana Neman Aiki: Injin Carnot (W) ya yi aiki

Manometer Tube - matsaloli da mafita
1. An cika bututun manometer da nau'ikan ruwa guda biyu. Yawan ruwa 1 shine ρ 1 = 0.8 g.cm -3 , kuma yawan ruwa 2 shine ρ 2 = 1 g.cm -3 , da tsayi h 1 = 10 cm, to menene tsayin h 2.
An sani:
Yawan ruwa 1 = 0.8 g.cm -3
Yawan ruwa 2 = 1 g.cm -3
Tsawo 1 = 10 cm
Ana nema: Tsawo 2
Makamashin Inji - matsaloli da mafita
Ka'idar makamashin aiki-injini
1. Ma'aunin gogayya tsakanin tubali da bene (μk ) shine 0.5. Menene matsar da abu(s)? Saurin gudu saboda nauyi shine 10 m/s 2.
An sani:
Ma'aunin gogayya mai motsi (μk ) = 0.5
Nauyin tubali (m) = 4 kg
Saurin gudu saboda nauyi (g) shine 10 m/s 2
Zafin jiki da zafi - matsaloli da mafita
1. A kan ma'aunin zafi na X, wurin daskarewar ruwa a -30 o da kuma wurin tafasar ruwa a 90 o . 60 O X = ….. o C.
An sani:
Wurin daskarewar ruwa = -30 o
Tafasar ruwan = 90 o
Ana so: 60 o X = ….. o C

Telescopes na ilmin taurari - matsaloli da mafita
1.
Dangane da jadawalin da ke sama, ƙayyade girman na'urar hangen nesa lokacin da idon da ke kallo ya sassauta.
Thermodynamics - matsaloli da mafita
Ka'idar farko ta thermodynamics
1. Dangane da jadawalin PV da ke ƙasa, menene rabon aikin da iskar gas ta yi a cikin tsari na I, da aikin da iskar gas ta yi a cikin tsari na II?
An sani:
Tsarin 1:
Matsi (P) = 20 N/m 2
Ƙarar farko (V1 ) = lita 10 = 10 dm 3 = 10 x 10 -3 m 3
