Answer: Sunday at 12h.
Explanation: The timezones are determined by the meridians, i.e., the longitudinal lines that crosses the Earth from pole to pole.
The initial referential is at GMT, abbreviation for <u>Greenwich</u> <u>Mean</u> <u>Time</u>, located at the Royal Observatory in the United Kingdom.
The Earth rotates 360° in 24 hours, so each 15° is exposed to the Sun for 1 hour. So, at each 15° we add an hour if the location is due to east or subtract an hour if the location is due to west.
Addis Ababa is located at 40°, which is in the band between 30° and 45°.
Counting from the referential, there are 3 timezones going east. So, we add 3 hours to the initial hour:
9h + 3h = 12h
And the day is the same since the difference is only 3 hours ahead.
Thus, fans located at 40° east will watch a football match on Sunday at 12h.
Answer:
b. flat rotation curves in spiral galaxies
Explanation:
Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.
Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.
The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.
Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
