(g = -9.80 m/s2 )QUESTION 7 The magnitude of the drag force FD is OF = -CAV2 where C is the drag coefficient, A is the area of the object facing the fluid, and d of the object. OF = CPAv2 where C is the drag coefficient, A is the area of the object facing the fluid, and is the density of the fluid. V is the speed of the object. OF. = - CPAv2 where C is the drag coefficient, A is the area of the object facing the fluid, and is the density of the fluid. V is the speed of the object. OF = - CPAv where C is the drag coefficient, A is the area of the object facing the fluid, and p is the density of the fluid. V is the speed of the object. OF = HON 10 points Save Answer\f
