a catapult yes. a trebuchet no
If you introduce air into a space where gravity is zero, then air exists there. A current example is the inside of the International Space Station, where the crew live and work in a "shirtsleeve environment" that includes air, pressure, and warmth, but they also live and work in an environment of weightlessness, or what is popularly but erroneously called "zero gravity".
It's possible. There is a zero gravity area in the sea.
Fountain pens depend on gravity to pull the ink down to the nib. In Zero gravity, they don't work.
Most egg timers would work in space (zero gravity) apart from the sand hourglass type. The rely on springs and gears to keep time not weights.
The zero gravity pen was originally used in space so astronauts wouldn't have to find a pen for example if the zero gravity pen floats then the astronauts would be able to see where a pen is because if the pen did not float then if one of the astronauts needed to write something down they would have to write.
A two-ton bus would have zero weight in zero gravity, since weight is dependent on the force of gravity. However, gravity has an infinite range, so gravity would only actually be zero at an infinite distance from the source of the gravity.
No
They cant, if the did they planet would fall apart, zero-gravity doesnt exist.
They wouldn't
Zero! that's why it is called zero gravity!

zero gravity
i would tell you if i knew
No.
Depends on the atmosphere. location, place, space and time of zero gravity
