Answer:
6.19 x 
m/
Explanation:
For this exercise we need to sum the forces on the y-axis and x-axis as follows:
∑
= N - mg = m.
= 0
From the exercise, we deduce there is no motion in y-axis, so:
N = mg
Then for x-axis we have:
∑
= H - 
= m.
= 0
Now, from the exercise we deduce that we are looking for the greatest static friction which means to have the maximun static friction to start moving, so at this point the acceleration is zero, so we can find horizontal force (H), which then will act in the airplane to move it. Therefore we have:
H = = 
= 
N = mg
H = (0.76)(84Kg)(9.8m/)
H = 625.63 N
Now we apply this force to the weight of the plane to find the greatest acceleration the mann can give to start moving the plane.

The water tank waves are transverse waves while the sound waves are longitudinal waves.
<h3>What is a wave?</h3>
A wave is a disturbance along a medium which transfers energy. We know that the water tank waves are transverse waves while the sound waves are longitudinal waves.
The difference between the two is that in the water waves, the direction of the wave motion is perpendicular to the disturbance while in the sound waves, the the direction of the wave motion is parallel to the disturbance.
