Explanation:
Some scholars don't agree with this theory that the Aryans migrated to the Indian subcontinent, but most of historians are arguing that during this migration they came from the North and destroyed the Dravidians who were living there. Their period that started during the migration is known as Vedic period.
A rotation 90° counterclockwise about the origin followed by a reflection across the y-axis
Answer:
1. spheroidal component
2. elliptical galaxy
3. irregular galaxy
4. spiral galaxy
5. disk component
6. cosmology
Explanation:
1. True, the globular cluster M13 belongs to the spherical component or spheroidal component of the milky way galaxy because globular clusters are usually found in galaxies.
2. Since most elliptical galaxy lack new stars they usually have very little cool gas or dust to make.
3. An irregular galaxy is a galaxy that does not have a unique regular shape like other galaxies. Because irregular galaxies are formed when galaxies collide they are more common in the universe 10 billion years ago when the collision is said to have started.
4. Since the milky way galaxy is found in a low-density regions and having a spiral structure that extend from its center into the galactic disc it is called spiral galaxy.
5. The sun is a star, and is located about 28,000 light years from the centre of the milky way galaxy.
Like all the other stars in the milky way galaxy, it is located in the disk component of our galaxy: the milky way galaxy.
6. Indeed, Cosmology involves studying the physical universe, its structure, dynamics, origin and evolution.
This study of the dynamics of the physical universe involves investigating how did distribution of galaxies changes with time.
Answer:
Silk Roads, Sea Roads, and Sand Roads?
Explanation:
The desire of elites for hard-to-find luxury items
from distant parts of the Eurasian network, as well as
the accumulation of wealth, especially among
merchants who participated in the trade, motivated
long-distance commerce. Sustaining the commerce were the support of empires and smaller states that benefited directly from the trade; the spread of religious traditions, including Islam and Buddhism, that through shared beliefs tied merchants and sometimes whole societies together over wide regions; and the development of technologies like larger ships and the magnetic compass.
