Answer is the highest temperature, so D
Higher temperatures allow for sound to move faster, since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.
Neat little fact: This is also why in the winter when there is snow on the ground, it seems more peaceful and quite. The snow absorbs the sound waves and the temperature makes them not travel as fast, getting more quite as they go.
The answer is Zip.

Answer:
A Ray I believe since it sounds like it.
Answer:
0 (Zero)
Explanation:
Definition of work done states that ,
Work done on an object is the force applied on that object in the direction of Displacement of the object .
means that ,
W = F.dS (Dot product of Force and displacement)
When the wall is acted upon by the force of 20 N , Wall does not move ,
Thus , displacement of the wall is zero.
So, W = 20×0 = 0.
Thus, Work done on the wall is zero.
Answer:x=79,202.77 ft
Explanation:
Given
plane is at a height of 32000 ft
angle of depression is 
let x the distance between the point directly below the plane and airport be x
from diagram
x=79,202.77 ft
distance between plane and airport
h=85,422.94 ft
