Answer 1

Answer:

Moving objects in fluids have streamline shapes, because , ... This frictional force depends on the shape of the body. By giving objects a special shape, that is streamlined shape, the force of friction acting on it can be minimised. Hence, it becomes easier for the body to move through the fluid.

Answer 2

Answer:

Answer:Objects moving in fluids face the friction of the fluid that opposes their motion. So objects moving in fluids must have unique shapes called streamlined shapes to reduce the fluid friction. ... Therefore, special shapes are designed to minimize the opposing frictional force.
