Answer:
Option B is correct ( difficulty in recovering from a stalled condition.)
Explanation:
Option B is correct ( difficulty in recovering from a stalled condition.)
If you load airplane in such manners CG has changed then it will have huge impact on the longitudinal stability. Due to this airplane would face difficulty in recovering from a stalled condition.
Stall is the phenomena in which air resistance is increased on the wings which causes decrease in lift. So it is important to remain with in CG limit put by manufacturer to avoid stall condition.
The electron arrangement of the outer energy level.
If there's no air resistance, then the diver keeps moving horizontally at 40 m/s, even after s/he jumps out of a perfectly good airplane.
Also, gravity ADDS 9.8 m/s of downward speed for every second the diver falls.
One second after leaving the airplane, the diver is moving horizontally at 40 m/s, and moving vertically downward at 9.8 m/s .
The question asks for the "downward velocity". That's 9.8 m/s .
The diver's TOTAL velocity is
√ (40² + 9.8²)
= √ (1,600 m²/s² + 96.04 m²/s²)
= √ (1,696.04 m²/s²)
= 41.2 m/s in some direction between
straight forward and straight down.
The best and most correct answer to the question is :
Alpha particles
Beta particles
Gamma rays
Cosmic radiation
Neutrons
Hope this helped you :)
