Which ONE of the following comments relating to DRAG is TRUE?

Drag increases as the speed of the vehicle increases
Drag can be minimised by increasing the surface area of the vehicle.
Drag can be decreased by enlarging the wings on a plane.
Turbulence and drag are not related

Some vehicles have space age aerodynamic shapes. An aerodynamic shape allows

the vehicle to have many things protruding from it without making the vehicle slower.
for greater drag and therefore keeping the vehicle down at a safer speed
passengers to become more comfortable in their seats.
the air to flow over its surface smoothly and without becoming turbulent.

Which ONE of the comments below is TRUE?

Four fins on a model rocket increases the PARASITE DRAG of the rocket
Painting a smooth coat of paint on the surface decreases BASE DRAG.
Shaping the nose cone into a point increase the PRESSURE DRAG of the model
Having six fins at the base of the rocket rather than 3 will increase its BASE DRAG.
