Want this question answered?
yes! :)
True
Gravity.
Gravity and Inertia
the pressure pushes the nebula together just like magnets to keep it from falling or collapsing, and the gravity pulls the exess debri into the nebula to keep it packed tight.
Yes, particles in the nebula attracted to one another by gravity?
yes! :)
True
All bodies that have mass, have gravity. The Helix Nebula is a large planetary nebula and will have "loads" of gravity.
a nebula is cloud of particles which forms into a star.
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
Dust and particles.
A nebula IS a cloud of dust and gas loosely held together by gravity.
the pressure pushes the nebula together just like magnets to keep it from falling or collapsing, and the gravity pulls the exess debri into the nebula to keep it packed tight.
