Isibonelo sesitsha esixhunywe epayipini elinomumo we-U

Izibonelo ezi-4 zamapayipi anomumo we-U Izitsha Ezixhunyiwe

1. Imikhumbi emibili u-A no-B igcwele uketshezi olunezinhlayiya ezahlukene, njengoba kuboniswe esithombeni. Uma ingcindezi engezansi kuka-A ilingana no-4/5 i-tekanan phansi kwe-B kanye ukuminyana uketshezi A = 1000 kg m^-3 , khona-ke ubuningi boketshezi ku-B bungu...

A. 1250 kg m^-3

B. 2500 kg m^-3

C. 3000 kg m^-3

D. 4000 kg m^-3

E. 5000 kg m^-3

Ingxoxo

Kuyaziwa ukuthi:

Ingcindezi phansi kwe-A (P_A) = Ingcindezi engaphansi kwe-B iphindwe ka-4/5 (4/5) P_B)

Ubuningi boketshezi u-A (ρ_A) = 1000 kg m^-3

Kubuziwe: Ubuningi boketshezi B (ρ_B)

Impendulo:

Ifomula yokucindezela kwe-hydrostatic koketshezi u-A ngu-P_A = ρ_A i-gh_A

RIfomula yokucindezela kwe-hydrostatic koketshezi B ngu-P_B = ρ_B i-gh_B

Ingcindezi phansi kwe-A = Ingcindezi ephindwe ka-4/5 esisekelweni se-B:

Ukuphakama koketshezi ku-A = ukuphakama koketshezi ku-B ukuze u-h_A kanye no-h_B kususiwe kulesi sibalo.

Ukusheshisa okubangelwa amandla adonsela phansi u-g kuyafana ngakho-ke kuyasuswa kulesi sibalo.

5 (ρ_A) = 4 (ρ_B)

5 (1000) = 4 (ρ_B)

ρ_B = 5000 / 4

ρ_B = 1250

Ubuningi boketshezi ku-B buyi-1250 kg m^-3

Impendulo efanele ngu-A.

2. I-U-tube igcwelengoketshezi olubili oluhlukene njengoba kuboniswe esithombeni esilandelayo! Uma ubuningi ρ₁ = 0,8 g.cm^-3, ρ₂ = 1 g.cm^-3, kanye no-h₁ = 10 cm, bese kuba ukuphakama h₂ kuyinto….

A. 5 cm

B. 6 cm

C. 7 cm

D. 8 cm

E. 10 cm

Ingxoxo

Kuyaziwa ukuthi:

Ubuningi 1 = 0,8 g.cm^-3

Ubuningi 2 = 1 g.cm^-3

Ukuphakama 1 = 10 cm

Kubuziwe: Ukuphakama 2

Impendulo:

Impendulo efanele ngu-D.

3. I-U-tube igcwele uketshezi oluhlukene olubili njengoba kuboniswe esithombeni esilandelayo! Uma ubuningi be-p₁ = 0,8 g.cm^-3, iphe₂ = 1 g.cm^-3, kanye no-h₁ = 10 cm, bese kuba ukuphakama h₂ kuyinto….

A. 5 cm
B. 6 cm
C. 7 cm
D. 8 cm
E. 10 cm

Ingxoxo
Kuyaziwa ukuthi:
Ubuningi 1 = 0,8 g.cm^-3
Ubuningi 2 = 1 g.cm^-3
Ukuphakama 1 = 10 cm
Kubuziwe: Ukuphakama 2
Impendulo:
Impendulo efanele ngu-D.

4. Naka isithombe esilandelayo:
I-U-tube iqale igcwaliswe ngamanzi anobukhulu obuyi-1000 kg.m.^-3 Ngemuva kwalokho, uwoyela wokupheka uthululwa kwelinye lamapayipi ukuze indawo ezinzile ibukeke njengesithombe. Uma ukuphakama kwekholomu yamafutha kungu-8 cm kanti ikholomu yamanzi ingu-5 cm, ubuningi bamafutha okupheka bungu….

A. 520 kg.m^-3
B. 525 kg.m^-3
C. 600 kg.m^-3
D. 625 kg.m^-3
E. 720 kg.m^-3

Ingxoxo
Kuyaziwa ukuthi:
Ubuningi bamanzi = 1000 kg.m^-3
Ukuphakama kwamanzi = 5 cm
Ukuphakama kwamafutha okupheka = 8 cm
Umbuzo: Ubuningi bamafutha okupheka
Impendulo:
Impendulo efanele ngu-D.
