Below is an attachment containing the solution.
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.

Answer:
(a) FN = m (g -
)
(b) vmin = 17.146 m/s
Explanation:
The radius of the arc is
r = 30m
The normal force acting on the car form the highest point is
FN = m (g -
)
If the normal force become 0 we have
m (g -
) = 0
or
g -
= 0
This way, when FN = 0, then v = vmin, so
g -
= 0
vmin =
= ![\sqrt[.]{9.8 m/s^{2} * 30m } = 17.146 m/s](https://tex.z-dn.net/?f=%5Csqrt%5B.%5D%7B9.8%20m%2Fs%5E%7B2%7D%20%2A%2030m%20%7D%20%3D%2017.146%20m%2Fs)
