The answer is D, or Outer Space.
Explanation:
Sound is implemented through mechanical wave transferral, which requires a medium (solid, liquid, or gas) to travel through. Because sound is a mechanical wave, it cannot travel through vacuums (space).
<span>CD stands for Compact Disk and ROM stands for Read Only Memory. CD-ROMS were designed to store information that the computers can read and you cannot overwirte on it. S,o the answer is the option C.: A CD-ROM is a compact disk that contains stored information that can be read on a computer.</span>
To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by

Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And

Therefore using the values given we can find the velocity through,


Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1


Therefore the cars goes to 145.3m/s
Don’t know sorry I’m just trying not a good person
Okay whats the question though?
