Please think! What makes an airplane start moving and take off? It's not the wheels, it's the thrust from engines moving the air. All the wheels do is hold up the plane and allow it to move relative to the ground.

LOL. Now that's funny. A quick answer would be "no" because the plane could not achieve the "airspeed" necessary to get air moving fast enough around its wings. That's the answer your teacher wants.
But -- consider, a conveyor belt that big and that fast (400mph, for crying out loud) would be carrying a lot of air with it -- a BIG WIND. The plane would take off as a result of the airspeed caused by the wind carried by the conveyor belt! LOL.

No,
Its all about the air movement across the wings. The air moves faster accross the top of the wing than the bottom causing a difference in preasure on either side of the wing. This is where the lift comes from.
Therefore if its on a conveyor belt then technically there is not wind moving across the wings so it is impossible for it to get any lift.

No, it needs to be passing through air in order to take off.
In your example, the engines would give thrust to the plane, the wheels would turn, but the conveyor belt would turn as well to keep the plane stationary, and therefore without airflow.
I believe that when you wrote the question, you may not have taken into consideration the fact that the engines are not connected to the wheels.

No , it will not fly, because its position is stationary relative to the air, the plane needs to gain velocity against the air which will lift the wings & make the plane flys.
So itis the movement of the airoplane & not the turning of the weeles which cause the plane to fly.

It doesn't matter if the plane is on wheels or conveyer belt. All that matters is that the airflow around the wings of the plane achieve the necessary amount of "lift" for take-off.

Yes, the plane will take off, despite the prevailing opinion here that the conveyor belt possesses the magical powers necessary to prevent the plane from actually moving.
And for all of those who followed with the wrong answer, thanks for the lecture on flight dynamics. We were all a bit puzzled as to exactly what causes airplanes to fly until you guys showed up.
Who dragged this stupid "riddle" out of the trash?

No the wings must generate lift by the movement of air flowing past.

No, there would be no airflow over wings therefore no lift therefore no take off
