it can not be more than 20kg...
Depends on the plane
The answer is no. A plane can fly many distances no matter what the weight is, unless it is too heavy, then it won't touch from the ground. The amount of fuel however does affect its distance. The more fuel you have the further a plane can go. However, if the plane is heavy it requires more fuel compared to a plane that is lighter going to the same destination.
The total of the plane, cargo and fuel.

each plane has a set take off speed , flap position and weight for take off
The maximum ramp weight is 397,800 kg and the max take off weight is 396,890 kg.
That depends on the plane's glide ratio, air speed, and angle of attack,and on how long it has been falling.It does NOT depend on the plane's weight.

Provided they do not exceed the cabinet weight and size limit, in theory yes, speakers can be taken on a plane in hand luggage.
Empty Weapons:18,200 Ib;max take off 27,200 Ib.
The A380 is an Airbus plane and not a Boeing. The A380-800 has an operating weight when empty of 610,200 pounds and a maximum weight on take-off of 1,235,000 pounds.
It depends very much on the speed at which the plane goes.
