A plane on the ground will weigh

The weight of the plane is  (mass) x (acceleration of gravity).

Neither of these changes when the plane rises from the ground.

Its weight on the ground is equal to (the same as) its weight in the air.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
