do 747s have propellers?

I would like to give props to everyone weighing in on the airplane question.
Like propellers, jet engines propel themselves (and the plane attached to them) through the air, regardless of ground speed.

How much air is moving beneath the wings if a conveyor is matching wheel speed?
Air pressure beneath the wing is what creates lift
Air pressure beneath the wing is what creates lift
Seems Wright to me
The only thing the conveyor belt would do is make the planes wheels turn twice as fast as they would otherwise, as the plane moved forward and took off
Can the plane take off? YES, if it turns around and takes off in the opposite direction.
Are you sure you graduated from high school? First off, no wings, no lift, no flight. Jet turbine engines do not cause a plane to fly. Wings cause a plane to fly. You need air speed for lift to occur. Otherwise all you have is ground speed.

You might want to back it down a few gears. The conveyor belt would have ZERO effect in preventing the jet from moving forward and creating enough speed for lift. Think about it. maybe you should have gone to a different high school? Sorry, couldn't resist
Somebody in this thread deserves this award. Not saying who.
You must have not understood the premise of the question to start with. The plane doesn’t move forward, at all, never. Think about it. The whole point of including the conveyor belt is the trick of the question. Chain the plane in place. The engines, whether turbine or propellor will not cause lift on the wings. Engine speed could be maxed out. If air speed is zero, then there is zero lift.
The plane moves. The wheels roll. The conveyor rolls at a matched speed in opposite direction. That is the premise.
Of course it takes off. The plane don't give a crap what the wheels are doing.
Think of a float plane.
