Answer:
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
