Answer: OLEDs
Explanation:
The nanotechnology uses the surface of the carbon materials to generate the electricity. The evaporation of water on the surface of carbon materials helps in generation of electrical energy due to generation of thermal energy.
OLEDs can be defined as solid-state devices that comprises of organic molecules like carbon that will create electricity by exposing a surface for generation of thermal energy.
Answer:
because there isn't any gravity there
Answer:
Object 2 has the larger drag coefficient
Explanation:
The drag force, D, is given by the equation:

Object 1 has twice the diameter of object 2.
If 

Area of object 2, 
Area of object 1:

Since all other parameters are still the same except the drag coefficient:
For object 1:

For object 2:

Since the drag force for the two objects are the same:

Obviously from the equation above, c₂ is larger than c₁, this means that object 2 has the larger drag coefficient
