Aplane on the ground will weigh:
a)more than a plane in the air
b)less than a plane in the air
c)the same as a plane in the air

A)more than a plane in the air

Explanation:

The weight of an object depends on its mass and the acceleration of gravity.

The weight of an object is:

w = m*g

where m is the mass and g is the acceleration of gravity. The mass of an object will be the same no matter how high it is, but it is different with the weight, since it depends on the gravitational attraction.

While an object is farther from the surface, it feels less gravitational attraction, so the value of g will be smaller and the weight will also be less than that of an object on the surface.

Therefore, a plane in the ground will weigh more than a plane on the air.
