Imagine a plane is sitting on a massive conveyor belt, as wide and as long as a runway.
The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction.
Can the plane take off?

Yes, presuming the wheels will "survive" their rolling speed, which is twice as high than normal.
The plane can take off for it gains it velocity from the thrust of the jets, not from acceleration by its wheels ... thus the conveyor belt doesn't play any role in this process. However, it accelerates the rolling speed of the wheels, so, measured by nowadays systems, these wheels probably will be destroyed and then the plane can't roll any more. If it didn't gain its take off speed before that happens, well, then it indeed can't take off any more :-)

The plane can take off normally provided the wheels are not damaged by double of the rotation speed.Remember the plane accelerates by jet engine or propeller and not by wheel like a car. So moving conveyor has little or no effect on the plane. If you convert a car to be a plane then it will never take off from the conveyor.

Yes, the plane can take off. It is actually realizing a speed twice that than normal since it is overcoming or at least maintaining the speed of the conveyor belt, therefore moving twice as fast.

Aircraft engineers have a saying: when the weight of the paperwork equals the weight of the plane, the plane will fly.
Well, that does not really apply here, so let look at it a bit different.
Airplanes get their lift by airflow over the wings. In you situtition, the air speed is 0, so there will be no lift.
The airplane will not fly.

The plane will NOT take off. In order for planes to fly, they need airflow over their wings, and according to Bernoulli's equation, it will fly. The conveyor belt alone will not cause the plane to fly.

The answer is NO!
Aerodynamics over the wings must play apart too! WIthout the airflow over the wings, the theory of aerodynamics will not work and therefore, plane can't be lifted!

yes the plane can take off provided its speed is double the speed of the belt so as to overcome the opposition of the belt.

No.
It requires forward speed to cause the wings to acquire lift.

I think no. I think the force of the plane itself has to be strong.

Of course it can. The wheels roll freely and have nothing to do with the propulsion system.
