<span>The earth as a whole rotates with a fixed angular velocity. Therefore, you
need to be at the rotation axis to have the smallest tangential speed. This
would be at the north or south pole.</span>
If you stand up in a big room and echo, your voice will echo
from the walls. As long as the room is empty. Since
the speed of sound is constant, depending on air density, the more humid the
air the faster and farther sound travels. The
speed of sound is constant, you could measure the time it takes for your voice
to echo off the walls. The same thing happens with Doppler radar, but it’s not voice,
it has higher frequency signals.<span> </span>
