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 Nguva yesimba - matambudziko nemhinduro 1

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: Carnot cycle - matambudziko nemhinduro 1

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: Chubhu yeManometer - matambudziko nemhinduro 1

Kuwanda kwemvura 1 = 0.8 g.cm ^-3

Kuwanda kwemvura 2 = 1 g.cm ^-3

Kureba 1 = 10 cm

Zvinodiwa: Kureba 2

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: Simba remuchina - matambudziko nemhinduro 1

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

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: Thermodynamics - matambudziko nemhinduro 1

Maitiro 1:

Kumanikidzwa (P) = 20 N/m ²

Vhoriyamu yekutanga (V ₁ ) = marita gumi = 10 dm ³ = 10 x 10 ^-3 m ³

Kubonderana - matambudziko nemhinduro

1. Chinhu A (3 kg) chinofamba nekumhanya kwe8 m/s uye chinhu B (5 kg) chinofamba nekumhanya kwe4 m/s. Kana kuroverana pakati pezvinhu A naB kwakanyatsosimba, chii chinoita kuti zvinhu A naB zvimhanye mushure mekuroverana?

Zvinozivikanwa:

Huremu hwechinhu A (m1 ₎ = 3 kg

Huremu hwechinhu B (m2 ₎ = 5 kg

Kumhanya kwechinhu A (v ₁ ) = 8 ms ^–1

Kumhanya kwechinhu B (v ₂ ) = 4 ms ^–1
