The correct answer is 'd'. An object in free fall seems to be weightless.
Explicación
## Step 1The problem is asking us to identify the correct statement about an object in free fall. Free fall is a type of motion that occurs when the only force acting on an object is gravity. ## Step 2In a vacuum, where there is no air resistance, an object in free fall would accelerate towards the Earth at a constant rate. This is because the only force acting on the object is gravity, which pulls it towards the Earth.## Step 3However, in the real world, there is air resistance, which can slow down the object's fall. This is because the air molecules in the atmosphere exert a force on the object, opposing its motion.## Step 4Despite the presence of air resistance, an object in free fall still experiences weightlessness. This is because the object is falling freely under the influence of gravity, and it is not being supported by any other force.
