Aping-pong ball has a mass of 2.3 g and a terminal speed of 9.2 m/s. the drag force is of the form bv2 what is the value of b?

Drag force is a force that resist the motion of a certain body through a fluid like air or water. This can be calculated through the equation,
                                    D = 0.5Cρv²
where D is drag, C is the drag coefficient, ρ is the density and v is the velocity. The value therefore of b in the item above is,
                                        b = 0.5Cρ

Gas will most likely  fill the container 

Transfer of electrons. hope it !
