No. Wind speed varies greatly depending on the weather.
If they push off with the exact same force and incur the exact same wind and friction resistance, and both have the same mass then indeed they should move away from each other at the same speed.
A series of barometers can be used to predict wind speed and direction. Wind will move from higher pressure areas to lower pressure areas. The higher the pressure differential the higher the wind speed will be.
It does. Usually, you'll be riding at about the same speed as the windspeed. If you and the wind is moving in the same direction, at the same speed, then you're not moving in relation to the wind. For you to feel the wind pushing you along, you have to be slower than the wind.
Yes. Fire moves with the wind, so they move at the same speed.
Air speed or ground speed?
It depends. Sometimes it can move at 20mph and sometimes it will really speed, depending on the wind.
cloud have no particular direction it move in the direction of wind
wind shear
162 is the base of it and it gives the air to take it from the soil. It is air that the atmosphere always to move in the troposphere.

An anemometer is used for measuring the speed of wind,
