Bongata - mathata le litharollo

1. Bophahamo ba ntho ke 8 cm ³ mme boima ba ntho ke digrama tse 84. Boima ba ntho ke bofe?

Tse tsejoang:

Bophahamo (V) = 8 cm ³

Boima (m) = digrama tse 84

Ho batloa: bongata (ρ)

Tharollo:

ρ = m / V = 84 dikgerama / 8 cm ³ = 10.5 dikgerama/cm ³

2. Bophahamo ba boloko ke 5 cm ^3. Haeba boima ba boloko ke 250 g/cm ³ , boima ba boloko ke bokae?

Tse tsejoang:

Bophahamo (V) = 5 cm ³

Botenya (ρ) = 250 g/ ^cm3

Ho batloa: Boima ba boloko

Tharollo:

ρ = m / V

ρ = bongata, V = bophahamo, m = boima

Boima ba boloko:

m = ρ V = (250 g/cm ³ )(5 cm ³ ) = 1250 dikgerama

3. Bophahamo ba metsi ke 35 cm ³ mme boima ba metsi ke digrama tse 60, boima ba metsi ke bokae.

Tse tsejoang:

Bophahamo ba metsi (V) = 35 cm ³

Boima ba metsi (m) = digrama tse 60

Ho batloa: bongata (ρ)

Tharollo:

bongata:

ρ = m / V = 60/35 = 1.71 dikgerama/cm ³

4. Boima ba tšepe ke digrama tse 120 mme bophahamo ba tshepe ke 60 cm ^3. Botenya ba tshepe ke bofe?

Tse tsejoang:

Boima (m) = digrama tse 120

Bophahamo (V) = 60 cm ³

Ho batloa: bongata

Tharollo:

ρ = m / V

ρ = dikgerama tse 120 / 60 cm ³

ρ = 2 dikgerama/ ^cm3

Tharollo:

Foromo ea bongata:

ρ = m / V

ρ = bongata, m = boima, V = bophahamo

Bongata - mathata le ditharollo 2

6. Ho latela setshwantsho se ka tlase, haeba boima ba ntho e le digrama tse 300, boima ba ntho eo ke bofe.

Tse tsejoang: Bongata - mathata le ditharollo 3

Boima (m) = digrama tse 300

Bophahamo (V) = bophahamo ba metsi a tsholohileng = 20 cm ³

Ho batloa: bongata

Tharollo:

ρ = m / V = 300 dikgerama / 20 cm ³ = 15 dikgerama/cm ³

7. Boima ba ntho ke digrama tse 316, bo kentswe ka setshelong jwalo ka ha ho bontshitswe setshwantshong. Boima ba ntho ke bofe.

Tse tsejoang: Bongata - mathata le ditharollo 4

Boima (m) = digrama tse 316

Bophahamo (V) = bophahamo ba metsi a tšolohileng = 40 ml

Ho batloa: bongata

Tharollo:

Boima = digrama tse 316 = 316/1000 kg = 0.316 kg

Bophahamo = 40 ml = 40/1000 lilithara = 4/100 lilithara = 0.04 lilithara

Litara e le 1 = 1 dm ³ = 1/1000 m ³ = 0.001 m ³

Lilithara tse 0.04 = (0.04)(0.001) m ³ = 0.00004 m ³

Botenya:

ρ = m / V = 0.316 kg / 0.00004 m ³ = 316 kg / 0.04 m ³ = 7900 kg/m ³

Bongata - mathata le ditharollo 5 Botenya ba lejoe bo ipapisitseng le setšoantšo ke…

Tse tsejoang:

Boima (m) = dikgerama tse 100 + dikgerama tse 20 = dikgerama tse 120 = 120 / dikhilograma tse 1000 = dikhilograma tse 0.120

Bophahamo (V) = 80 ml – 60 ml = 20 ml = 20 / 1000 litres = 2/100 litres = 0.02 litres

Litara e le 1 = 1 dm ³ = 1/1000 m ³ = 0.001 m ³

Lilithara tse 0.02 = 0.02 x 0.001 m ³ = 0.00002 m ³

Ho batloa: bongata

Tharollo:

Botenya:

ρ = m / V = 0.120 kg / 0.00002 m ³ = 120 kg / 0.02 m ³ = 6000 kg/m ³
