A flying airplane is affected by which force or forces? A. friction only B. gravity only C. gravity and friction only D. gravity, friction, and an applied force

D. gravity, friction, and an applied force.

Explanation:

There are 4 forces that act on an airplane in motion and they are:

Gravity and drag:

It acts in a downward direction—toward the center of the Earth.

Lift:

It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.

Thrust:

It is the force that propels a flying machine in the direction of motion.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
