#### Answer

Yes, you can tell.

#### Work Step by Step

The ball that is falling within the vacuum will have a constant acceleration. The position of the ball will follow the equation $y=-\frac{1}{2}gt^2$.
The ball that is falling in air suffers air resistance, and if the tube is tall enough, eventually reaches terminal velocity and falls with constant speed. On the photograph, it will travel equal distances in equal time intervals.
