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 voltage across a membrane forming a cell wall is 84.0 mV and the membrane is 9.40 nm thick. What is the electric field stren
Katarina [22]

Answer:

8.9*10^6 V/m

Explanation:

The expression for electric field strength E is given as

E=\frac{V}{d}

where V= voltage

           d= distance of separation

Given data

voltage= 84 mV= 84*10^-^3\\distance= 9.4*10^-^9

substituting our given data into the electric field strength formula we have

E= \frac{84*10^-^3}{ 9.4*10^-^9} \\\\E= \frac{84}{9.4} *10^-^3^-^(^-^9^)\\\\E= \frac{84}{9.4} *10^-^3^+^9\\\\E= \frac{84}{9.4} *10^6\\\\E=8.9*10^6  V/m
