Given that,
The attached figure shows an airplane is traveling from North Africa to England.
To find,
The arrow that shows the direction gravity pulls the plane.
Solution,
The force of gravity always acts in the downward direction, The weight of an object is given by :
W = mg
Arrow 2 shows the direction of gravitational pull.
Answer:
4 m/s² down
Explanation:
We'll begin by calculating the net force acting on the object.
The net force acting on the object from the left and right side is zero because the same force is applied on both sides.
Next, we shall determine the net force acting on the object from the up and down side. This can be obtained as follow:
Force up (Fᵤ) = 15 N
Force down (Fₔ) = 25 N
Net force (Fₙ) =?
Fₙ = Fₔ – Fᵤ
Fₙ = 25 – 15
Fₙ = 10 N down
Finally, we shall determine the acceleration of the object. This can be obtained as follow:
Mass (ml= 2.5 Kg
Net force (Fₙ) = 10 N down
Acceleration (a) =?
Fₙ = ma
10 = 2.5 × a
Divide both side by 2.5
a = 10 / 2.5
a = 4 m/s² down
Therefore, the acceleration of the object is 4 m/s² down
ΔT= 81°C was the increase in temperature.
<h3>
steps</h3>
As evidenced by energy conservation
To increase its temperature, all of its kinetic energy will be converted to thermal energy.
ΔT
then divide both sides by the object's mass.
ΔT
therefore, a temperature shift is described as
ΔT= 
ΔT= 
/ 2 x 387
ΔT= 81°C
ΔT= 81°C was the increase in temperature.

The higher the phase margin the more stable is the system and for these tuned parameters, the phase margin is around
. Some researcher given their theory on the phase margin that there are changes of getting sluggish response for larger phase margin but using TLBO algorithm the settling time and as well as peak overshoot of the system shows better response as compared to conventional techniques.
