Od For no reason​

Answer 1

Answer:

To reduce the friction of fluid

Answer 2

A boat or an aeroplane has a pointed or tapering front head to reduce the friction of fluid.

• The air resistance is a great factor behind the speed reduction of a flying aircraft.
• Now, the air resistance is directly proportional to the frontal surface area of the flying object.
• Less surface area will create scopes for less air resistance.
• To obtain this less frontal area as well as the less air resistance, the pointed tip is used.
