Mehlala ea lipotso tsa ho teteana: ho teba, ho phaphamala, ho phaphamala

7 Mohlala oa Mathata a Bongata Ho Teba Ho Phaphamala ha Metsi Ho Phaphamala ha Metsi

1. Sheba tafole ea lintho tse 'maloa tse tiileng ka tlase!
Lintho tse 'ne tse thathamisitsoeng tafoleng e ka holimo li behiloe ka sejaneng se nang le metsi (botenya ba metsi = 1,0 g/cm³). Setšoantšo se bontšang hantle boemo ba lintho ka metsing ke...

Puisano
Haeba bongata ntho > bongata ba metsi ebe ntho eo ea teba.
Haeba boima ba ntho = boima ba metsi, ntho eo e tla phaphamala.
Haeba boima ba ntho < boima ba metsi, joale lintho tse phaphametseng.
Lintho tsa 3 le tsa 4 li na le boima bo fetang ba metsi kahoo lia teba. Ntho ea 1 le ea 2 li na le boima bo bonyenyane ho feta ba metsi kahoo lia phaphamala.
Karabo e nepahetseng ke D.

2. Sheba tafole ea bongata ba lintho tse 'maloa tse nang le mefuta e fapaneng ka tlase!

Ho latela data ena, haeba dintho tse nne di kenngwa ka hara sejana, setshwantsho se nepahetseng ke...

Puisano
Botenya ba ntho ea 1 (mokelikeli) bo boholo ho feta botenya ba ntho ea 2 (mokelikeli), kahoo ntho ea 1 e behiloe ka tlase 'me ntho ea 2 e behiloe ka holimo. Mohlala, metsi a na le botenya bo boholo ho feta oli. Haeba oli e tšeloa ka setshelong se tletseng metsi, oli e tla phaphamala holim'a metsi.
Botenya ba ntho ya 3 (e tiileng) bo bonyenyane ho feta botenya ba ntho ya 1 (e metsi) mme bo boholo ho feta botenya ba ntho ya 2 (e metsi), ka hona ntho ya 3 e teba nthong ya 2 mme e phaphamala nthong ya 1. Botenya ba ntho ya 4 (e tiileng) bo boholo ho feta botenya ba ntho ya 1 le botenya ba ntho ya 2 hoo ntho ya 2 e tebang dinthong tsa 1 le tsa 2.
Karabo e nepahetseng ke A.

3. Sheba tafole ea lintho tse latelang!

Sebaka se nepahetseng haeba ntho e tiileng e kentsoe ka har'a mokelikeli se bontšoa setšoantšong...

Puisano
Metsi a leoatle le peterole ke metsi, ha khalase le leqhoa e le lintho tse tiileng. Boima ba metsi a leoatle bo feta ba peterole, kahoo metsi a leoatle a tlase 'me peterole e holimo.
Botenya ba leqhoa bo boholo ho feta boima ba peterole le boima bo bonyenyane ho feta boima ba metsi a leoatle hoo leqhoa le tebang ka peteroleng le ho phaphamala metsing a leoatle.
Botenya ba khalase bo boholo ho feta boima ba peterole le metsi a leoatle hoo khalase e tebang ka har'a peterole le metsi a leoatle.

4. Lintho tse peli A le B tse boima bo lekanang li qoelisoa ka metsing. Ntho A ea phaphamala ha ntho B e phaphamala. Polelo e nepahetseng mabapi le ketsahalo ena ke…

(1) Boima ba ntho B bo feta boima ba ntho A

(2) Matla a ho phaphamala a amohelwang ke ntho B a feta boima ba yona.

(3) Matla a ho phaphamala a amohelwang ke dintho tsena ka bobedi a itshetlehile ka botebo

(4) Lintho ka bobeli li na le matla a tšoanang a ho phaphamala

Puisano

(1) Ntho A e phaphamala ha ntho B e ntse e phaphamala, ka hona, boima ba ntho A bo feta boima ba ntho B

(2) Polelo ea 2 e nepahetse. Ntho e phaphamala ha matla a ho phaphamala a le maholo ho feta matla a eona a khoheli

(3) Polelo ea 3 e fosahetse. Ho tsitsa ha metsi ha ho itšetlehe ka botebo ba metsi, empa ho itšetlehile ka phapang ea botebo ba metsi pakeng tsa bokaholimo bo ka holimo le bo ka tlase ba ntho e qoelitsoeng ka metsing.

(4) Polelo ea 4 e fosahetse. Lintho tsena tse peli li na le matla a fapaneng a ho phaphamala, ho latela bophahamo ba ntho e qoelitsoeng ka metsing.

5. Leqhoa le teteaneng la 0,90 g/cm³ tšela ka oli e nang le boima ba 0,80 g/cm³Matšoao a hlahang ke…

A. leqhoa le phaphametseng

B. 1/9 ea leqhoa e qoelitsoe

C. Karolo ea halofo ea lithapo tsa leqhoa

D. 8/9 ea leqhoa e qoelitsoe

E. leqhoa le teba ka ho feletseng

Puisano

Botenya ba leqhoa bo boholo ho feta boima ba oli kahoo leqhoa le teba ka ho feletseng.

Karabo e nepahetseng ke E.

6. Lintho A le B li ka har'a sejana se nang le mokelikeli joalokaha ho bontšitsoe setšoantšong. Bongata bo ka bang teng ba mokelikeli, lintho A le B ke…

Puisano

Ntho A e phaphametse, boima ba ntho A < boima ba mokelikeli.

Dikotwana tsa ntho B, boima ba ntho B > boima ba mokelikeli.

Karabo e nepahetseng ke B.

7. Sheba tafole e latelang ea tekanyo ea boima le bophahamo!

Sebaka se nepahetseng sa lintho ha li beoa ka har'a mokelikeli (botenya ba mokelikeli 1 gr/cm³) ke…

Puisano

1. Boima = boima / bophahamo = digrama tse 8 / 40 cm³ = 1/5 gram/cm³

2. Boima = boima / bophahamo = digrama tse 60 / 60 cm³ = 1 gram/cm³

3. Boima = boima / bophahamo = digrama tse 200 / 40 cm³ = 5 gram/cm³

Botenya ba mokelikeli = 1 gram/cm³

E phaphamala haeba boima ba ntho < boima ba mokelikeli.

E phaphamala haeba boima ba ntho = boima ba mokelikeli.

Ho teba haeba boima ba ntho > boima ba mokelikeli.
