Why the double cone apparatus able to roll upwards?
Because it only appears to be rolling uphill--it is actually rolling downhill, as it must. The reason for the illusion is as the V-shaped grove the cone rolls widens the contact point on the cone are further from the center thus allowing the CG of the cone to lower as it rolls. Many so-called "Mystery Spots" (like the one in Santa Cruz, CA) use the technique using a ball rolling down a narrow groove that gets imperceptibly wider thus creating the illusion the ball is rolling uphill when it fact is not.
Does the size of the ball effect how fast it rolls?
The size of a ball does affect how fast it rolls. Surface also play a major role in how fast a ball will move.
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
In what direction should you turn wheels when parking uphill?
To the left, so if the car rolls it will hit the curb and not swing into traffic.
Why does a ball roll when you blow on it?

No because mass doesn't means how it affect far it rolls
