Nanotechnology and microtechnology devices are both very tiny. however, one property of nanotechnology distinguishes it from microtechnology. what is this unique property? nanotechnology can create new products. nanotechnology is not affected by gravity. nanotechnology travels at the speed of light if needed. nanotechnology can display wave-particle duality.

The nanotechnology can display wave-particle duality.

Microtechnology is technology developed at micro meter scale that is 10^-6.

Nanotechnology is technology developed at nano meter scale 10^-9.

The wavelength of matter becomes observable at nano meter scale. So, it is possible to observe wave particle duality at nanotechnology but not at microtechnology.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
