Nguva yekusagadzikana kwezvikamu - matambudziko nemhinduro
1. Mabhora maviri akabatana netsvimbo, sezvakaratidzwa mumufananidzo uri pazasi. Usafuratira huremu hwetsvimbo . Huremu hwebhora P i600 gramu uye huremu hwebhora Q i400 gramu. Ndeipi nguva yekusashanda kwehurongwa pamusoro peAB?
Zvinozivikanwa:
Chikamu chekutenderera chinonzi AB.
m p = magiramu 600 = 0.6 kg, m q = magiramu 400 = 0.4 kg
r p = 20 cm = 0.2 m, r q = 50 cm = 0.5 m
Zvinodiwa: Nguva yekusashanda zvakanaka kwehurongwa
4 Basa reNet Simba regiravhiti Simba reKinetic - Matambudziko neMhinduro
1. Chinhu chinorema 5-kg chiri pakakwirira kwemamita gumi pamusoro pevhu. Kukurumidza kunokonzerwa negiravhiti i10 m/s 2. Ndeipi basa rinoitwa pachinhu chacho kuti chiiswe kumusoro kusvika pakukwirira kwemamita gumi nemashanu pamusoro pevhu?
Zvinozivikanwa:
Huremu hwechinhu (m) = 5 kg
Kureba (h) = mamita mashanu
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Zvaidiwa: Basa rakaitwa pachinhu ichi kuti chikwidzwe kumusoro kusvika pakakwirira mamita gumi nemashanu kubva pasi.
Nguva yesimba - matambudziko nemhinduro
1. Kana F R iri simba guru reF 1 , F 2 , uye F 3 , simba guru reF 2 na x nderei?
Zvinozivikanwa:
Simba reNet (F)R) = 40 N
Simba 1 (F 1 ) = 10 N
Simba (F 3 ) = 20 N
Zvinodiwa: Hukuru hwesimba F 2 uye daro ra x
14 Mutemo waBoyle Mutemo waCharles Mutemo waGay-Lussac - Matambudziko neMhinduro
1. Kumanikidzwa kwemhepo yevhiri remotokari i432 kPa netembiricha ye15 o C. Mushure memaawa akati wandei, kumanikidzwa kwemhepo i492 kPa. Kana kuwedzera kwemhepo kukasatariswa , tembiricha yemhepo iri muvhiri ingave yakaita sei ?
Zvinozivikanwa:
Kumanikidzwa kwekutanga (P 1 ) = 432 kPa
Kumanikidzwa kwekupedzisira (P 2 ) = 492 kPa
Tembiricha yekutanga (T 1 ) = 15 o C
Zvinodiwa: Tembiricha yekupedzisira (T 2 )
Carnot cycle - matambudziko nemhinduro
1. Kana kupisa kukatorwa neinjini (Q 1 ) = 10,000 Joules, ibasa rei rinoitwa neinjini yeCarnot?
Anozivikanwa:
Tembiricha yakaderera (T 2 ) = 400 K
Kupisa kwakanyanya (T 1 ) = 800 K
Kupinza kupisa (Q 1 ) = 10,000 Joules
Zvinodiwa: Basa rinoitwa neCarnot engine (W)
Solution:
Manometer chubhu - matambudziko nemhinduro
1. Chubhu yemanometer yakazadzwa nemhando mbiri dzezvinwiwa. Kuwanda kwemvura 1 ndi ρ 1 = 0.8 g.cm -3 , uye kuwanda kwemvura 2 ndi ρ 2 = 1 g.cm -3 , uye kukwirira h 1 = 10 cm, saka kukwirira kwe h 2 chii.
Zvinozivikanwa:
Kuwanda kwemvura 1 = 0.8 g.cm -3
Kuwanda kwemvura 2 = 1 g.cm -3
Kureba 1 = 10 cm
Zvinodiwa: Kureba 2
Simba remakanika - matambudziko nemhinduro
Musimboti wesimba rekushanda nemechanical
1. Chiyero chekukweshana kwekinetic pakati peblock nefloor (μ k ) i0.5. Chii chinonzi displacement yechinhu/zvinhu? Kukurumidza kunokonzerwa negravity i10 m/s 2.
Zvinozivikanwa:
Chiyero chekukweshana kwekinetic (μ k ) = 0.5
Huremu hwebhuroko (m) = 4 kg
Kukurumidza kunokonzerwa negiravhiti (g) ndeye 10 m/s 2
Kupisa nekupisa - matambudziko nemhinduro
1. Pa thermometer X, mvura inofanira kuomeswa nechando pa -30 oz uye mvura inofanira kufashaira pa 90 oz . 60 oz X = ….. o C.
Zvinozivikanwa:
Mvura inotonhora zvikuru = -30 o
Pombi yekufashaira yemvura = 90 oz
Zvinodiwa: 60 o X = ….. o C
Solution:
Materesikopu emuchadenga - matambudziko nemhinduro
1.
Zvichibva pagirafu riri pamusoro, sarudza kukura kweteresikopu kana ziso rekuona rakasununguka.
Thermodynamics - matambudziko nemhinduro
Mutemo wekutanga we thermodynamics
1. Zvichibva pagirafu yePV iri pazasi, chii chiri chiyero chebasa rinoitwa negasi mukuita kwekutanga, nebasa rinoitwa negasi mukuita kwekutanga kwekutanga II?
Zvinozivikanwa:
Maitiro 1:
Kumanikidzwa (P) = 20 N/m 2
Vhoriyamu yekutanga (V 1 ) = marita gumi = 10 dm 3 = 10 x 10 -3 m 3
