What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives? it remains unchanged. it increases. it balances the weight. it decreases.

A submarine or a ship can float because the weight of water that it displaces is equal to the weight of the ship. ... To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below).

Answers:

It would seem that it would be B you'd have to decrease the buoyant force by removing the air from the dive tanks and filling them with water. And in a way it's C - by allowing water into the dive tanks, you are balancing the weight of the sub with the water around it.

b

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
