Explanation:
1. Mass of an object
2. Distance between the objects
Answer:
a) 588,000 N
b) 294000 N
Explanation:
Given that
Density of water = 1000kg/m3
(g) = 9.8m/s2
volume is given as (V)= 5m*4m*3m
a) force will be equal to weight of water

b) at either end




[A = wh]

F = 294000 N
Answer: Remain unchanged
Explanation:
The boat with water barrel overboard floats in swimming pool when weight of the water displaced by the boat is equal to the buoyant force acting on the boat.
When the water in the barrel is poured overboard, the level of the swimming pool level would remain unchanged as the weight of the boat with the water and barrel would remain unchanged ( as the density and volume of the whole system remains same) and hence, the weight of the water (of the swimming pool) displaced by the boat would remain same.
A boat loaded with a barrel of water floats in a swimming pool. When the water in the barrel is poured overboard, the swimming pool level will <u>remain unchanged. </u>
