<span>The motion of the medium is parallel to a longitudinal wave
and perpendicular to a transverse wave.</span>
One of Kepler's laws is that the orbits of planets are elliptical. It's not a suggestion.
BTW, circles are ellipses too, but so special that their likelihood is close to zero.
If the sound comes from the right side, the waves reach the right ear before the left ear. if the sound comes from the left side, the waves reach the left ear before the right ear. The difference between the phases of waves reaching both ears is detected by the ears and then interpreted by the brain
Yes because if not people wouldn't understand how did you calculate electric field strength.
C. The higher the altitude the less gravity affects you
