Why is it easier to swim in sea water than in the river water?
Answer Posted / phanindra
The density of the sea water is more than the density of river water. Thus upward thrust is larger. When a body is submerged in sea water the weight of the sea water is displaced is equal to the weight of the river water. A larger body is to be submerged in it. Hence it is easier to swim in a sea water than a river water.
