Question

15 fill in the blank 1 point a skydiver who just opened his parachute choose your answer... choose your answer... rolling friction sliding friction static friction fluid friction

Explanation:

When a skydiver opens the parachute, the air (a fluid) exerts a frictional force against the motion of the skydiver. Fluid friction acts between layers of a fluid (in this case, air) or between an object and a fluid. Rolling friction occurs when an object rolls over a surface (e.g., a wheel on the road). Sliding friction is when an object slides over a surface (e.g., a book sliding on a table). Static friction is the force that keeps an object at rest (e.g., preventing a book from sliding down an inclined plane when it is not moving). Since the skydiver - parachute system is moving through air (a fluid), fluid friction is the relevant type of friction.

Answer:

Fluid friction
