Answer:
Mass of the combined system = 201.8 Kg
Weight of the combined system = 1977.64 N
Explanation:
Given:
Mass of the plastic tank = 2 kg
Volume of the plastic tank = 0.2 m³
Density of water = 999 Kg/m³
Now, the volume of water in the tank = volume of tank = 0.2 m³
Also,
Mass = Density × Volume
therefore,
Mass of water = 999 × 0.2 = 199.8 Kg
Thus, the combined mass = Mass of tank + Mass of water in the tank
or
the combined mass = 2 + 199.8 = 201.8 Kg
Also,
Weight = Mass × Acceleration due to gravity
or
Weight = 201.8 × 9.8 = 1977.64 N
