I would say pressure, but it might depend on what you mean by stability. Pressure will tell you how many particles and how energized those particles are, the more particles the higher the pressure, the harder it is to change or remove the atmosphere due to the larger mass of it. Also consistent pressure measurements can tell you how stable the atmosphere in a particular region is. So if stability means how consistent are the weather conditions, pressure can be a good indicator too, differences and changing pressures can cause weather catastrophes like tornados and hurricanes.

The answer would be true.
Explanation:
Although some silk in is more flexible than others, there are many varieties. There are high medium and low flexibility. Even though there are different levels, it is still considered a trait. Again, the answer in True.
Hope this helped you. I did some research on this before, so this should be correct. If you aren’t satisfied then you can ask me a question! Have a nice day.

Vx = 2*cos30 = 1.73m's
Other words:
D = Vo*t = 1.4 * 21 = 31.5m. @ 30 Deg.
Dy = 31.5*sin30 = 15.75 m.
