Oge nke inertia maka ihe ndị dị n'ime - nsogbu na ngwọta
1. Bọọlụ abụọ ejiri mkpanaka jikọọ, dịka egosiri na eserese dị n'okpuru. Lelee oke mkpara ahụ . Ibu bọọlụ P bụ gram 600, ibu bọọlụ Q bụkwa gram 400. Gịnị bụ oge inertia nke sistemụ gbasara AB?
A maara:
Axis nke ntụgharị bụ 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
Achọrọ: Oge nke inertia nke sistemụ ahụ
4 Ọrụ Net Ike ike ndọda Ike Kinetic - Nsogbu na Ngwọta
1. Ihe dị kilogram ise n'ogo mita iri n'elu ala. Ọsọ ọsọ nke ike ndọda bụ mita iri n'ime awa abụọ . Gịnị ka a na- arụ n'ihe ahụ iji bulie ya elu ruo mita iri na ise n'elu ala?
A maara:
Ibu ihe (m) = 5 kg
Ogologo (h) = mita 10
Ọsọ ọsọ nke ike ndọda (g) = 10 m/s 2
Achọtara: E tinyere ọrụ n'ihe ahụ iji bulie ya elu ruo n'ogo nke mita iri na ise n'elu ala.
Oge ike - nsogbu na ngwọta
1. Ọ bụrụ na F R bụ ike net nke F 1 , F 2 , na F 3 , kedu ka ike F 2 na x dị?
A maara:
Ike netwọk (F)R) = 40 N
Ike 1 (F 1 ) = 10 N
Ike (F3 ) = 20 N
Achọtara: Oke ike F 2 na anya nke x
14 Iwu Boyle Iwu Charles Iwu Gay-Lussac – Nsogbu na Ngwọta
1. Nrụgide ikuku nke taya ụgbọala bụ 432 kPa , okpomọkụ ya dịkwa 1 5 o C. Mgbe awa ole na ole gachara, nrụgide ikuku bụ 492 kPa. Ọ bụrụ na eleghara mmụba anya , kedu okpomọkụ ikuku dị na taya ahụ?
A maara:
Nrụgide mbụ (P1 ) = 432 kPa
Nrụgide ikpeazụ (P2 ) = 492 kPa
Okpomọkụ mbụ ( T 1 ) = 15 oC
Achọrọ: Okpomọkụ ikpeazụ ( T2 )
Okirikiri Carnot - nsogbu na ngwọta ya
1. Ọ bụrụ na injin ahụ na-amịkọrọ okpomọkụ (Q 1 ) = Joules 10,000, kedu ọrụ injin Carnot na-arụ?
Mara:
Okpomọkụ dị ala (T2 ) = 400 K
Okpomọkụ dị elu (T 1 ) = 800 K
Ntinye okpomọkụ (Q1 ) = Joules 10,000
Achọtara: Ọrụ nke injin Carnot (W) rụrụ

Manometer tube - nsogbu na ngwọta
1. A na-ejupụta ọkpọkọ manometer na ụdị mmiri abụọ. Njupụta nke mmiri 1 bụ ρ 1 = 0.8 g.cm -3 , njupụta nke mmiri 2 bụkwa ρ 2 = 1 g.cm -3 , na elu h 1 = 10 cm, kedu ka elu h 2 dị?
A maara:
Njupụta nke mmiri mmiri 1 = 0.8 g.cm -3
Njupụta nke mmiri mmiri 2 = 1 g.cm -3
Ogologo 1 = 10 cm
Achọrọ: Ogologo nke abụọ
Ike mekaniki - nsogbu na ngwọta
1. Oke nke esemokwu kinetic dị n'etiti blọk na ala (μ k ) bụ 0.5. Gịnị bụ mgbanwe nke ihe(s)? Ọsọ ọsọ nke ike ndọda bụ 10 m/s 2.
A maara:
Ọnụọgụ nke esemokwu kinetic (μ k ) = 0.5
Ibu nke blọk (m) = 4 kg
Ọsọ ọsọ nke ike ndọda (g) bụ 10 m/s 2
Okpomọkụ na okpomọkụ - nsogbu na ngwọta
1. Na temometa X, ebe mmiri na-ajụ oyi na -30 o na ebe mmiri na-esi na 90 o . 60 o X = ….. o C.
A maara:
Ebe oyi mmiri na-atụ = -30 o
Ebe mmiri na-esi mmiri = 90 o
Achọrọ: 60 o X = ….. o C
