Explanation:
It is due to buoyancy that human swimmers, fish, ships, and icebergs stay afloat. Some applications of buoyancy are given in the points below.
- Submarine
Buoyancy makes it possible for swimmers, fishes, ships, and icebergs to stay afloat. Some of the prominent applications of buoyancy are given below:
- Hot Air Balloon
The atmosphere is filled with air that exerts buoyant force on any object. A hot air balloon rises and floats due to the buoyant force. It descends when the balloon’s weight is higher than the buoyant force. It becomes stationary when the weight equals the buoyant force.
- Ship
A ship floats on the surface of the sea because the volume of water displaced by the ship 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 seawater. Therefore, the buoyant force acting on the ship is large enough to support its weight.
- Fish
A certain group of fishes uses Archimedes’ principle to go up and down the water. To go up to the surface, the fish will fill its swim bladder (air sacs) with gases (clever isn’t it?). The gases diffuse from their own body to the bladder and thus making the body lighter. This enables the fish to go up
