Answer 1

Answer:

(D) Bus do not have streamlined shape.

Answer 2

D. bus

Explanation:

The friction when something moves through a liquid or gas is called a drag. Shapes that are designed to reduce drag are called streamlined shapes. They resemble a bird in flight or a fish. Cars, airplanes, rockets and speedboats are all shaped in such a way that they are streamlined to reduce maximum drag, so friction is minimum on these objects.

Bus is not streamlined.
