Question

Explain why objects moving in fluids must have special shapes.​

Answer 1

$\huge\bold{\mathbb{\purple{☆A{\pink{N{\green{S{\blue{W{\red{E{\orange{R☆}}}}}}}}}}}}}$

The objects moving in fluids must have a special shape to overcome the fluid friction acting on them. Efforts are therefore made to minimise the friction, so objects are given special shape having pointed fronts with little broader middle portion which gets tapered at the back called streamlined.
