lubricating
C
propeller
D
polishing
Ask EduPadi AI for a detailed answer
Correct Option: A
Air friction (air resistance) opposes motion through air.
- Streamlining: Shaping an object aerodynamically to reduce air resistance.
- Lubricating: Reduces friction between solid surfaces, not air friction.
- Propeller: Generates thrust, doesn't reduce friction.
- Polishing: Reduces surface roughness, not air friction.
Therefore, the friction due to air mass can be reduced by streamlining.
