Answer:
False. Astrology is not a science.
Explanation:
Astrology is a collective term for ideas about the supposed connection between the fate of people and events on Earth and the position of the celestial bodies. It mainly concerns the places in the sky of the sun, moon and planets, which were referred to as stars in ancient times, usually against the background of the fixed stars in the Zodiac. Although astrology cannot be confirmed despite research, and scientists have long rejected the principles of astrology as pseudoscience, many people continue to practice and / or believe in it.
The Doppler effect says that the observed wavelength is shortened
when the source is approaching the observer, and lengthened when
the source is receding from the observer.
All we can say about the police car and its siren is that the sound/color
has a shorter wavelength as it approaches us, and a longer wavelength
as it recedes.
Any of these pairs of answers would say that:
A -- A
C -- A
D -- A
or
D -- D
For each of these pairs, the second wavelength is longer than the first one.
(We don't know which pair is the actual one, because we don't know the actual color of the police car.)
