E. Nonsense longitudinal waves have all of these properties
It is the only one that has both a partially molten metallic core and reasonably rapid rotation.
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
Geocentric:
-The model is Earth centered
-Retrograde motion is explained by epicycles.
Heliocentric:
-This model is Sun-centered.
-Retrograde motion is explained by the orbital speeds of planets.
Both geocentric and heliocentric:
-Epicycles and deferents help explain planetary motion.
-Planets move in circular orbits and with uniform motion.
-The brightness of a planet increases when the planet is closest to Earth.
