Question

when water fills a submarines floating tanks,overall density of submarine
a.decreases
b.staysa the same
c.increases
d.reduces the buoyant force

Answer 1

The total mass of a submarine when the floating tanks are filled with water is greater than if the tanks are empty. Obviously, the volume of a submarine remains the same. As we know, the density is calculated as Mass/Volume. So, the right answer is c - density of a submarine increases.
