Answer:
1989.4 N
Explanation:
Volume of tank, V = 0.2 m^3
density of water, d = 1000 kg/m^3
mass of tank, m = 3 kg
Mass of water in the tank, M = Volume of tank x density of water
M = V x d
M = 0.2 x 1000 = 200 kg
Total mass = M + m = 200 + 3 = 203 kg
total weight, W = total mass x g
W = 203 x 9.8 = 1989.4 N
Thus, the total weight of the combined system is 1989.4 N.
