The correct answer is: C. Neither (A) nor (B)
Wing loading is the ratio of the mass of an aircraft to the area of its wing. It is a measure of how much lift an aircraft needs to generate to stay in the air. The higher the wing loading, the more lift an aircraft needs to generate, and the faster it will need to fly to stay in the air.
Take-off distance is the distance required for an aircraft to take off. It is affected by a number of factors, including the aircraft’s weight, the runway length, and the headwind.
Powder loading is the amount of powder that is used to propel a rocket. The higher the powder loading, the more thrust a rocket will have, and the faster it will accelerate.
A. Landing speed is directly proportional to the wing loading.
This is not correct. Landing speed is affected by a number of factors, including the aircraft’s weight, the landing gear configuration, and the wind speed. The wing loading does not have a direct effect on landing speed.
B. Wing loading remaining constant, the take off distance is directly proportional to the powder loading.
This is also not correct. Take-off distance is affected by a number of factors, including the aircraft’s weight, the runway length, and the headwind. The wing loading does not have a direct effect on take-off distance.
C. Neither (A) nor (B)
This is the correct answer. Neither wing loading nor powder loading have a direct effect on landing speed or take-off distance.
