tanks provided more protection on land and submarines provided more in water?
Tank Submarine
a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water. use the formula density= mass / volume as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
The air found in the submarine makes it float
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
That is a ballast tank used to alter the angle of the submarine up or down
Submarine ballast tanks and their number depend entirely on the type of boat and its submerged displacement capacity. In general though, they're pretty big, on average about 6000 square feet or more.
the Tank,submarine,and the helicopter.
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
yes, as long as it was being towed by a submarine.
because of density
to keep the sub level or help it to dive and surface
The slanted armor offered extra protection to the tank.
