Answer 2

Answer:

(c) The benefits of the special shape of an airplane are:

(i) Fluid friction is reduced, (iii) Energy loss is as low as possible, and (iv) An airplane can fly like a bird.

Explanation:

• Fast-moving vehicles are given a streamlined shape because it allows them to cut through the air more quickly, increasing their speed.
• Their streamlined design helps to reduce fluid friction and minimize drag so that the body travels through the air with the least amount of resistance.
• As a result, it aids in simple air movement.
