Oge nke inertia maka ihe ndị dị n'ime - nsogbu na ngwọta
1. Bọọlụ abụọ ejiri mkpanaka jikọọ, dịka egosiri na foto dị n'okpuru. Lelee nke mkpanaka ukaIbu bọọlụ P bụ gram 600, ibu bọọlụ Q bụkwa gram 400. Gịnị bụ oge nke inertia nke sistemụ gbasara AB?
A maara:
Axis nke ntụgharị bụ 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
A chọrọ: Oge nke inertia nke sistemụ ahụ
4 Ọrụ Net Ike ike ndọda Ike Kinetic - Nsogbu na Ngwọta
1. Ihe dị kilogram ise n'ogologo mita iri n'elu ala. Ọsọ ọsọ n'ihi ike ndọda bụ 10 m/s2. Gịnị bụ ọrụ e mere ihe ahụ iji bulie ya elu ruo n'ịdị elu nke mita iri na ise n'elu ala?
A maara:
Mass nke ihe (m) = 5 kg
Ogologo (h) = mita 10
Ọsọ ọsọ n'ihi ike ndọda (g) = 10 m/s2
Chọrọ: 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 FR bụ ike net nke F1, F.2, na F3, kedu ka ike F dị2 na x?
A maara:
Ike netwọk (F)R) = 40 N
Ike 1 (F)1) = 10 N
Ike (F)3) = 20 N
Chọrọ: Oke ike F2 na anya nke x
14 Iwu Boyle Iwu Charles Iwu Gay-Lussac – Nsogbu na Ngwọta
1. Nrụgide ikuku nke taya ụgbọala bụ 432 kPa na okpomọkụ nke 15 oC. Mgbe awa ole na ole gachara, mgbali nke ikuku bụ 492kPa. Ọ bụrụ na eleghara mgbasawanye anya, gịnị bụ okpomọkụ nke ikuku dị na taya ahụ?
A maara:
Nrụgide mmalite (P1) = 432 kPa
Nrụgide ikpeazụ (P2) = 492 kPa
Okpomọkụ mbụ (T1) = 15 oC
Chọrọ: Okpomọkụ ikpeazụ (T)2)
Okirikiri Carnot - nsogbu na ngwọta ya
1 okpomọkụ injin ahụ na-amịkọrọ (Q)1) = 10,000 Joules, kedu ọrụ ndị ahụ rụrụ Injin kabọn?
Mara:
Okpomọkụ dị ala (T)2) = 400 K
Okpomọkụ dị elu (T)1) = 800 K
Ntinye okpomọkụ (Q)1) = 10,000 Joule
Chọrọ: Ọrụ nke injin Carnot (W) rụrụ

Manometer tube - nsogbu na ngwọta
1. A tube manometer e ji ụdị mmiri abụọ jupụta. njupụta nke mmiri mmiri 1 bụ ρ1 = 0.8 g.cm-3, na njupụta nke mmiri mmiri 2 bụ ρ2 = 1 g.cm-3, na ịdị elu h1 = 10 cm, kedu ka ịdị elu nke h dị2.
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
Chọrọ: Ogo 2
Ike mekaniki - nsogbu na ngwọta
1. Ọnụọgụ nke esemokwu kinetic n'etiti blọk na ala (μ)k) bụ 0.5. Gịnị bụ nnyefe nke ihe(ndị)? Ọsọ ọsọ n'ihi ike ndọda bụ 10 m/s2.
A maara:
Ọnụọgụ nke esemokwu kinetic (μ)k) = 0.5
Mass nke ngọngọ (m) = 4 kg
Ọsọ ọsọ nke ike ndọda (g) bụ 10 m/s2
Okpomọkụ na okpomọkụ - nsogbu na ngwọta
1. Na temometa X, ebe oyi na-atụ mmiri na -30o na ebe mmiri na-esi na ya na 90o. 60OX = …… oC.
A maara:
Ebe oyi mmiri na-atụ = -30o
Ebe mmiri na-esi mmiri = 90o
A chọrọ: 60oX = …… oC
