Answer:
dust cloud
Explanation:
Stars are formed from the accumulation of the dust as well gases in the solar system. The dust and the gases collapses due to the the gravity forces and the stars are formed.
They are formed within the clouds of the dust and gases and are scattered in the galaxies. The stars are formed in a million of years from the dust clouds.
In the context, Abdul have a picture of a dust cloud which looks smoky and dusty which is the initial stage of the stars formation due to the gravity. It is the region of the star that looks like a cloud of dust before the formation of the star.
Answer:
Up first are Mercury and Venus. Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
I'm assuming the question is supposed to be like this:
How does the Orbital velocity of a satellite depends on the mass of the satellite?
Answer
It is independent of mass of satellite.
Answer:
An electrically polarized object can carry no net charge
Example: charge Q at +x and charge -Q at -x for no net charge
An electrically charged object has a net charge on the object
