Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.
Answer: They originated in Europe after the Middle Ages.
Explanation:
Absolute monarchies arose under the absolute rule of kings. The best example of an absolutist monarchy and rule is France and its King Louis XIV. The king removed all obstacles to have complete control over the state. He surrounded himself with proven and obedient people and thus ensured absolute rule.
An example of a limited monarchy can be found in England. The parliament decides a country in which there is a king but no absolute power, but the country's political situation. A limited monarchy is the British's effort to avoid complete control of one man in the state.
Answer: y=-3
Explanation:
Equation of a line that passes through (a,b) and (c,d) is given by :-
The equation of the line that passes through the points (-4,-3) and (3,-3) :
Hence, the equation of the line that passes through the points (-4,-3) and (3,-3) : y=-3
