put the word submarine on it
you shoot a cannon.
You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
You have to bring the word submarine down to the bottom of the screen.
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.
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.
You grab the word submarine and pull it down.
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.
The density of a submerged submarine is about the same as the density of the fluid it is submerged in, which is typically seawater. This allows the submarine to float or sink based on its buoyancy and weight.
The Confederate submarine 'H L Hunley' was the first submarine to sink an enemy ship
pressurised water is filled in the outer cell. and air is removed.
A submarine floats and sinks by adjusting its buoyancy through the use of ballast tanks. When the submarine wants to sink, it fills these tanks with water, increasing its weight and causing it to descend. To float, the submarine expels the water from the ballast tanks, replacing it with air, which decreases its weight and allows it to rise. This ability to control buoyancy enables submarines to navigate at various depths in the water.
