From the given motions, let's determine the example which is not an example of a wave motion.
Wave motion can be defined as the transfer of energy from one point to another without the actual transfer of matter between the points.
From the given examples, the example which which we can say does not represent a wave motion is: a person dancing.
An earthquake’s energy travelling through the core of the planet is an example of wave motion since the energy travels through one point to the other.
A tsunami event occurring after an earthquake is also an example of a wave motion.
A vibrating Slinky showing crests and troughs is an example of wave motion.
While the sound of a tuba is an example of a sound wave,
Therefore, the example which does NOT represent a wave motion is a person dancing.
ANSWER:
A). A person dancing.
I think the answer is c. the more characteristics they have in common. Sorry if wrong.
Answer:![\vec{v_R}=\hat{i}[-329.11]+\hat{j}[516.18]](https://tex.z-dn.net/?f=%5Cvec%7Bv_R%7D%3D%5Chat%7Bi%7D%5B-329.11%5D%2B%5Chat%7Bj%7D%5B516.18%5D)
Explanation:
Given
Plane is initially flying with velocity of magnitude ![v=600\ mph](https://tex.z-dn.net/?f=v%3D600%5C%20mph)
at angle of
with North towards west
Velocity of plane airplane can be written as
![v_a=600(-\sin 40\hat{i}+\cos 40\hat{j})](https://tex.z-dn.net/?f=v_a%3D600%28-%5Csin%2040%5Chat%7Bi%7D%2B%5Ccos%2040%5Chat%7Bj%7D%29)
Now wind is encountered with speed of
at angle of ![N45^{\circ}E](https://tex.z-dn.net/?f=N45%5E%7B%5Ccirc%7DE)
![v_w=80(\cos 45\hat{i}+\sin 45\hat{j})](https://tex.z-dn.net/?f=v_w%3D80%28%5Ccos%2045%5Chat%7Bi%7D%2B%5Csin%2045%5Chat%7Bj%7D%29)
resultant velocity
![\vec{v_R}=\vec{v_a} +\vec{v_w}](https://tex.z-dn.net/?f=%5Cvec%7Bv_R%7D%3D%5Cvec%7Bv_a%7D%20%2B%5Cvec%7Bv_w%7D)
![\vec{v_R}=600(-\sin 40\hat{i}+\cos 40\hat{j})+ 80(\cos 45\hat{i}+\sin 45\hat{j})](https://tex.z-dn.net/?f=%5Cvec%7Bv_R%7D%3D600%28-%5Csin%2040%5Chat%7Bi%7D%2B%5Ccos%2040%5Chat%7Bj%7D%29%2B%2080%28%5Ccos%2045%5Chat%7Bi%7D%2B%5Csin%2045%5Chat%7Bj%7D%29)
![\vec{v_R}=\hat{i}[-385.67+56.56]+\hat{j}[459.62+56.56]](https://tex.z-dn.net/?f=%5Cvec%7Bv_R%7D%3D%5Chat%7Bi%7D%5B-385.67%2B56.56%5D%2B%5Chat%7Bj%7D%5B459.62%2B56.56%5D)
![\vec{v_R}=\hat{i}[-329.11]+\hat{j}[516.18]](https://tex.z-dn.net/?f=%5Cvec%7Bv_R%7D%3D%5Chat%7Bi%7D%5B-329.11%5D%2B%5Chat%7Bj%7D%5B516.18%5D)
for direction ![\tan \theta =\frac{516.18}{329.11}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%5Cfrac%7B516.18%7D%7B329.11%7D)
![\tan \theta =1.568](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D1.568)
