A 2-kg plastic tank that has a volume of 0.2 m3 is filled with liquid water. Assuming the density of water is 1000 kg/m3, determine the weight of the combined system. The weight of the combined system is N.

1,981.62 N

Explanation:

Data provided in the question:

Mass of the Plastic tank = 2 kg

Volume of the liquid water in the tank = 0.2 m³

Density of water = 1000 kg/m³

Now,

We know

Density = Mass : Volume

Thus,

Mass = Density * Volume

therefore,

Mass of the water in the tank = 1000 * 0.2

= 200 kg

Thus,

The mass of the combined system = 2 kg + 200 kg

= 202 Kg

Also,

Weight in N = Mass * Acceleration due to gravity (g)

and,

g = 9.81 m/s²

Therefore,

The weight of the combined system = 202 kg * 9.81 m/s²

= 1,981.62 N
