Question

Give two practical applications of floating.

Answer 1

Answer:

hy your answer

Explanation:

A submarine has a large ballast tank, which is used to control its position and depth from the surface of the sea. A submarine submerges by letting water into the ballast tank so that its weight becomes greater than the buoyant force. The atmosphere is filled with air that exerts buoyant force on any object.

Answer 2

Hey mate here's your solution:-

• Submarine

A submarine has large belaz tank which is used to control its position and depth from the surface of the sea.

A submarine submerges by letting water into the ballast tank, so that its weight becomes greater than the buoyant force .

conversely it floats by reducing water in the ballast does its weight is less than the buoyant force .

• Hot air balloon

The atmosphere is filled with air that exerts Buoyant force on any object .

The hot air balloon Rises and flows due to the Buoyant force when the surrounding air is greater than its weight it decides When The Balloons weight is higher than the buoyant force it become stationary when the weight equal to the buoyant force.

The weight of the hot air balloon can be controlled by varying the quantity of hot air in the balloon.

• Ship

A ship floats on the surface of the sea because the volume of water displaced by the step is enough to have a weight equal to the weight of the ship.

A ship is constructed in a way so that the shape is Hollow to make the overall density of the ship lesser than the sea water therefore the Buoyant force acting on the ship is large enough to support its weight .

A ship sumerged lower in fresh water as fresh water density is lesser than sea water ships will float higher in cold water as cold water has a relatively higher density than warm water .

I hope this solution will help you
