A barge is 15.0 m wide and 75.0 m long and has vertical sides. The bottom of the hull is 1.20 m below the water surface. What is the weight of the barge and its cargo, if it is floating in fresh water of density 1000 kg/m3

Respuesta :

Answer:

[tex]1.32\times 10^7N[/tex]

Explanation:

According to Archimedes principle the weight = buoyancy force

We have given length = 75 m

Width = 15 m

Height =1.2 m

So volume =75×15×1.2=1350 [tex]m^3[/tex]

Density [tex]d=1000kg/m^3[/tex]

We know that mass m = density ×volume [tex]=1000\times 1350=1350000\ kg[/tex]

Weight [tex]w=mg=1350000\times 9.8=1.32\times 10^7N[/tex]
