Answer / abhinav
It is easier to swim in seas than in river as we know U=dgv, the density of sea is greater than density of river due to the presence of salt in sea. U is directly propostional to density, increase in density increases the upthrust. The more the upthrust lesser will be the apparent weight of that body. (Upthrust = Apparent weight - real weight). Less apparent weight makes movement of limbs inside sea easier. Thus, an object can swim easily in seas.

Answer / kriti sharma
It is easy to swim in the sea because it has more buoyant force/upthrust whereas river ha less buoyant force dye to flowing water

Answer / m.s. mohan raj
Sea water is denser than the river water it has more buoyant force is applied that is why we
are able to swim in sea water than river water

Answer / priyadarshini basu
Sea water has a density of 1.026 g/cc due to presence of salt in it.
River water has density 1 g/cc.
Upthrust =v*d*g.
Volume of body immersed remains same.Acceleration due to gravity also is same.Since density of sea water is relatively more than that of river water,therefore loss in weight in sea water is more than that of river water.Thus it can swim more easily than in river water.

Answer / g purnachandra
Because the sea water have large surface than the upthrust is increase
| Is This Answer Correct ? | 9 Yes | 16 No |
Answer / gaurav jaiswal
Because the surface of sea water is large than river water and sea water contain large density
