Magirasi ekuparadzanisa - matambudziko nemhinduro
1. A nesefa ine mipata inosvika 4000 pa sendimita inovhenekerwa ne monochromatic chiedza uye inogadzira mutsetse wakajeka wechipiri pakona ye30°. Chii chinonzi wavelength yechiedza chakashandiswa? (1 Å = 10-10 m)
Zvinozivikanwa:
Daro riri pakati pemipata (d) = 1 / (mipata 4000 / cm) = 0.00025 cm = 2.5 x 10-4 masendimita = 2.5 x 10-6 mamita
Odha (n) = 2
Pasina makumi matatu nemavirio = 0.5
1 Å = 10-10 m
2 Musimboti wesimba rekushanda Simba risingachengetedzi Kufamba mundege yakatsamira nekukakavadzana - Matambudziko nemhinduro
1. Bhokisi rinotsvedza pasi ndege yakatsamira nekukweshana. Chii chinonzi bhokisi velocity bhokisi rinorova pasi riini? Chiyero che kukweshana kwekinetic i0.4. Kukurumidza kwesimba nekuda kwegiravhiti i10 m/s2.
Zvinozivikanwa:
Kureba kwekutanga (h)o) = 6 m
Kureba kwekupedzisira (h)t) = 0 m
Kumhanya kwekutanga (v)o= = 0 (vhara pakutanga pakuzorora)
Kukweshana kwekinetic (μ)k= = 0.4
Basa rinoitwa mumaitiro ethermodynamic - matambudziko nemhinduro
1. Ku gasi rakanaka inodzvanywa kubva panhamba 1 kuenda panhamba 2 sezvakaratidzwa pagirafu iri pazasi. Sarudza kuti basa zvinoitwa negasi.
mhinduro
1 litre = 0.001 m3
Zvinozivikanwa:
Pressure 1 (P)1) = 10 kPa = 10,000 Pa = 10,000 N/m2
Kumanikidzwa 2 (P)2) = 20 kPa = 20,000 Pa = 20,000 N/m2
Kubonderana uye kuchengetedzwa kwesimba remakanika - mapurobhu nemhinduro
1. Zvinhu zviviri zvakafanana uremu, m1 = m2 = 0.5 kg yakadonhedzwa kubva pakukwirira kwakafanana sezvakaratidzwa mumufananidzo uri pazasi. Radiyumu yedenderedzwa i 1/5 m. Iyo kudhumhana pakati pezvinhu zvese zviri zviviri panonyatsonamira. Sarudza kuti velocity chinhu chimwe nechimwe mushure mekubonderana. Kuwedzera nekuda kwegiravhiti iri 10 m/s2.
Zvinozivikanwa:
Huremu hwechinhu (m) = m1 = m2 = 0.5 kg
Kureba kwekutanga (h)1) = 1/5 m
Kureba kwekupedzisira (h)2= = 0 (hwaro hwenzira)
Kufamba kweMomentum Impulse uye Projectile - Matambudziko neMhinduro
1. Bhora re 0.2-kg richapinzwa mugomba C, sezvakaratidzwa mumufananidzo uri pazasi. Munhu anorova bhora anorova musekondi 0.01 uye nzira yeBC yakafamba musekondi imwe chete. Sarudza hukuru hwesimba kuitira kuti bhora rigone kupinzwa mugomba C. Kuwedzera nekuda kwegiravhiti iri 10 m/s2.
Zvinozivikanwa:
Angle (θ) = 60o
Misa yebhora (m) = 0.2 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Nguva yenguva (Δt) = 0.01 masekondi
Kufamba kwemutsetse kusingaenzaniswi - matambudziko nemhinduro
1.
Tafura iri pamusoro inoratidza data rezvinhu zvitatu zvinofamba daro rakafanana pa kukurumidza nguva dzose.
Ndeipi kumhanya kwekupedzisira kwechinhu P uye kumhanya kwekutanga kwechinhu Q?
Dzidziso yeKinetic yemagasi uye mutemo wekutanga wethermodynamics - matambudziko nemhinduro
1. Magasi akakodzera ari mumudziyo une huwandu hwemarita mana uye kumanikidzwa kwawo kuri 3 atm (1 atm = 105 Nm-2). The magasi akakodzera inopisa nekumanikidzwa kunogara kuripo kubva pa27oC kuti 87oC. The kupisa simba yegesi i9 JK-1Chii chinonzi huwandu hwekupedzisira hwemagasi uye shanduko yesimba remukati memagasi?
mhinduro
Maitiro eIsobaric (kumanikidzwa nguva dzose)
Zvinozivikanwa:
Huwandu hwekutanga hwegasi (V)1) = marita mana
Kutenderera kwemiviri yakaoma - matambudziko nemhinduro
The mnguva yesimba
1. Masimba matatu anoshanda padanda rine hurefu hwemamita matanhatu, sezvakaratidzwa mumufananidzo uri pazasi. Chii chinonzi torque yemagetsi inotenderera danda rakatenderedza poindi O se axis yekutenderera?
Zvinozivikanwa:
Mutsetse wekutenderera panzvimbo yeO.
Simba 1 (F)1) = F
Daro riri pakati pemutsetse wekuita waF1 ne axis yekutenderera (r)1) = mamita makumi matanhatu
Zvitubu zvakatevedzana uye zvakafanana - matambudziko nemhinduro
1. Chinhu che 160-gram chinonamira pamucheto wechitubu uye kuchinja kwehurefu hwechitubu i4 cm. Chii chinonzi kuchinja kwehurefu hwetatu? zvitubu zvakabatana zvakatevedzana uye zvakafanana, sezvakaratidzwa mumufananidzo uri pazasi?
Zvinozivikanwa:
Kuchinja kwehurefu hwechitubu (Δx) = 4 cm = 0.04 m
Misa (m) = magiramu 160 = 0.16 kg
Kuwedzera nekuda kwegiravhiti (g) = 10 m/s2
Maitiro ekufamba kwese kwese - matambudziko nemhinduro
1. Pure ine nguva ye inertia Ini = 2/5 MR2 ine huremu hwe2 kg. Kana nguva yesimba Papulley pane 4 Nm saka chii chinonzi linear acceleration yepulley. Kukurumidza kunokonzerwa negravity g = 10 ms-2.
Inozivikanwa :
Nguva yekusashanda kwepulley (I) = 2/5 MR2
Misa yepulley (M) = 2 kg
Nguva yesimba (τ) = 4 Nm
