Diffraction gratings - nsogbu na ngwọta
1. A na-eji ìhè monochromatic na-enwu enwu n'ime grating nwere oghere 4000 kwa sentimita ma na-emepụta ahịrị na-egbuke egbuke nke abụọ n'akụkụ 30°. Kedu ka ogologo ebili mmiri nke ìhè ejiri mee ihe? (1 Å = 10 -10 m)
A maara:
Anya dị n'etiti oghere (d) = 1 / (nkwụsị 4000 / cm) = 0.00025 cm = 2.5 x 10 -4 cm = 2.5 x 10 -6 mita
Usoro (n) = 2
Sin 30 o = 0.5
1 Å = 10 -10 m

1 lita = 0.001 m 3
A maara:
Nrụgide 1 (P 1 ) = 10 kPa = 10,000 Pa = 10,000 N/m 2
Nrụgide nke 2 (P 2 ) = 20 kPa = 20,000 Pa = 20,000 N/m 2

1. Ihe abụọ nwere otu oke ibu , m 1 = m 2 = 0.5 kg dara site n'otu elu ahụ dịka egosiri na eserese dị n'okpuru. radius nke okirikiri ahụ bụ 1/5 m. Mkpọkọ dị n'etiti ihe abụọ ahụ na-agbanwe agbanwe nke ọma. Chọpụta ọsọ nke ihe ọ bụla mgbe ihe ahụ kụsịrị. Ọsọ ọsọ nke ike ndọda bụ 10 m/s 2.
A maara:
Ibu nke ihe (m) = m1 = m2 = 0.5 n'arọ
Ogologo mbụ (h 1 ) = 1/5 m
Ogologo ikpeazụ (h 2 ) = 0 ( isi ụzọ )
Mmetụta Mmalite na Mbugharị Mbugharị - Nsogbu na Ngwọta
1. A ga-etinye bọọlụ dị kilogram 0.2 n'ime oghere C, dịka egosiri na eserese dị n'okpuru. Onye kụrụ bọọlụ ahụ kụrụ bọọlụ ahụ n'ime sekọnd 0.01, ụzọ BC gakwara n'ime sekọnd 1. Chọpụta oke ike ahụ ka e wee tinye bọọlụ ahụ n'ime oghere ahụ. C. Ọsọ ọsọ n'ihi ike ndọda bụ 10 m/s 2.
A maara:
Nkuku (θ) = 60 o
Ibu nke bọọlụ (m) = 0.2 kg
Ọsọ ọsọ nke ike ndọda (g) = 10 m/s 2
Oge etiti oge (Δt) = 0.01 sekọnd

A maara:
Olu mbụ nke gas (V1 ) = lita 4
Mgbanwe nke ahụ siri ike - nsogbu na ngwọta
Oge ike
1. Ike atọ na-arụ ọrụ na ogwe osisi nwere ogologo mita isii, dịka egosiri na eserese dị n'okpuru. Gịnị bụ ike net nke na-agbagharị ogwe osisi ahụ gburugburu isi ihe O dị ka axis nke ntụgharị?
A maara:
Axis nke ntụgharị na isi O.
Ike 1 (F 1 ) = F
Anya dị n'etiti ahịrị ọrụ nke F 1 na axis nke ntụgharị (r 1 ) = mita 3
Mmiri ndị dị n'usoro na ndị yiri ya - nsogbu na ngwọta
1. Ihe dị gram 160 na-arapara n'otu nsọtụ nke isi iyi, mgbanwe n'ogologo isi iyi ahụ bụ 4 cm. Gịnị bụ mgbanwe n'ogologo isi iyi atọ ejikọtara n'usoro na parallel , dịka egosiri na foto dị n'okpuru?
A maara:
Mgbanwe n'ogologo nke mmiri (Δx) = 4 cm = 0.04 m
Ibu (m) = gram 160 = 0.16 kg
Ọsọ ọsọ nke ike ndọda (g) = 10 m/s 2
Mgbanwe nke mmegharị ntụgharị - nsogbu na ngwọta
1. Pulley nwere oge inertia I = 2/5 MR 2 nwere oke nke 2-kg. Ọ bụrụ na oge ike dị na pulley bụ 4 Nm, kedu ihe bụ ọsọ nke pulley. Ọsọ ọsọ nke ike ndọda bụ g = 10 ms -2.
Mara :
Oge nke inertia nke pulley (I) = 2/5 MR 2
Ibu nke pulley (M) = 2 kg
Oge ike (τ) = 4 Nm
