Why the ship is more submerged in fresh water than in salty water?
Density of salty water is more than fresh water, so more upthrust in salty water.
Arrange the densities of the liquids in decending order.
d3 > d2 > d1
What does the picture explain about change of upthrust?
Larger the volume of the body submerged in the fluid, greater is the upthrust.
