What begins to take shape in the center of nebular?
In the center of a nebula, gas and dust begin to collapse due to gravitational forces, forming a swirling disc known as a protoplanetary disk. Within this disk, material gradually accumulates and clumps together to form planetesimals, which are the building blocks of planets.
What is the most important factor that causes matter in a nebula to form clumps?
Gravity is the most important factor that causes matter in a nebula to form clumps. As particles within the nebula come together due to gravitational attraction, they begin to accumulate into regions of higher density, eventually leading to the formation of clumps and eventually protostars.
Does the Andromeda galaxy rotate?
Yes, it does, the rotation period can be calculated using 21cm radio waves and the Doppler principle. Answer: All galaxies rotate as do all planets around stars and just about everything else. It is the centripetal force of rotation that prevents objects from falling together due to the attractive force of gravity. If an isolated mass of stars or dust or gas were assembled in space and the contents had no rotational motion, the whole mass would begin to accelerate towards its own center due to gravity. So, while such clumps of matter can exist, they have all presumably condensed into planets or star or black holes.
When do you say that a star is born?
A star is born when nuclear fusion reactions begin in its core, leading to the release of energy in the form of light and heat. This process marks the transition from a cloud of gas and dust to a stable stellar body.
What position should the microscope stage be in when you first begin to focus in on an object?
The microscope stage should be in its lowest position to avoid damaging the objective lens when you first begin to focus on an object. Begin focusing with the coarse adjustment knob and then use the fine adjustment for finer focusing.
