Question

How will density help in manufacturing of ships and aircraft

Answer 1

Answer:

Density helps the Ships to float with the help of the buoyant force. As the density of ship is less than the water, the ships float.

According to the Archimedes principle, the buoyant force(upward force of water) is proportional to the water displaced.

Answer 2

Answer:

Explanation is given below.

Explanation:

The bouncy force is given as $F=d_{l} Vg$ where $d_{l}$ is the density of liquid in which object immerse and V is portion of volume into the water.

If density of material is less than the density of liquid then the material float.

While if the density of the material is higher than the density of liquid then the material drown.

Hence the density of material helps in manufacturing ships and aircraft.
