Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
When a falling object has reached its teminal velocity its accleration?
When the velocity stops changing, then, by definition, the acceleration is zero.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
What is the acceleration of an object that reache terminal velocity?
Zero, by definition. "Terminal velocity" implies that the velocity no longer changes.
Meaning of zero acceleration?
Zero acceleration means no change in velocity and no force on the zero accelerating body.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
Can velocity of an object change when its acceleration is constant?
Certainly! By definition, the acceleration is the change, so it will change unless that amount is zero.

It it possible for an object to be sationary while under acceleration?
"Stationary" means zero speed. The object's speed is not changing, and the direction of the speed is obviously also not changing.By definition then, acceleration is zero.
Can a body moving in a circle zero velocity and constant acceleration in circular motion have?
Nein. If it's moving, by definition it has non-zero velocity.
When a falling object has reached its teminal velocity its accleration?
When the velocity stops changing, then, by definition, the acceleration is zero.

No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.

Zero, by definition. "Terminal velocity" implies that the velocity no longer changes.
What is the acceleration of a car that maintains a constant velocity of 100 kilometers per hour for 10 seconds?
The answer is very simple. The words "constant velocity" are the definition of zero acceleration.
Can an object acceleration if its velocity is constant?
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
Meaning of zero acceleration?
Zero acceleration means no change in velocity and no force on the zero accelerating body.
Does a object in mechanical equilibrium have zero acceleration?
By the definition of mechanical equilibrium, Yes. Because the sum of forces is equal to zero, it can be seen from the equation F=ma that the total acceleration on the object must be zero in order for the equation to hold. The mass is only a constant in this equation in this situation, and remains unchanged.
