What two events can upset the balance between gravity and pressure in a nebula?
Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
If a star dies how big is the explosion?
The size of the explosion from a dying star, known as a supernova, can vary depending on the size and mass of the star. Supernovae release an immense amount of energy, and for a brief period, can outshine an entire galaxy. The explosion is powerful enough to create heavy elements and can also leave behind a dense core such as a neutron star or a black hole.
What happens when a supernova explosion occurs near a black hole?
When a supernova explosion occurs near a black hole, the intense gravitational pull of the black hole can cause the material from the supernova to be pulled towards it. This can result in the formation of an accretion disk around the black hole, leading to the release of a powerful burst of energy in the form of jets of high-energy particles and radiation.
What are the key differences between a supernova and a hypernova in terms of their explosive power and impact on the surrounding environment?
A supernova is a powerful explosion of a star, while a hypernova is an even more powerful explosion. Hypernovae release more energy and have a greater impact on their surroundings compared to supernovae.
What are two well-known nebulae?
Two well-known nebulae are the Orion Nebula (Messier 42) and the Crab Nebula (Messier 1). The Orion Nebula is a diffuse cloud in the constellation Orion, visible to the naked eye, while the Crab Nebula is a remnant of a supernova explosion observed in the year 1054.
Which type of supernova is created by the merger of two white dwarfs?
A Type Ia supernova is created by the merger of two white dwarfs. This type of supernova occurs when the combined mass of the white dwarfs exceeds a critical limit, leading to a thermonuclear explosion that destroys the star.
When does supernova occur?
A supernova occurs when a massive star reaches the end of its life cycle and undergoes a catastrophic explosion. This explosion can outshine an entire galaxy for a brief period of time before fading away.
When a star that is more than 40 times bigger than the sun dies what is it called?
It depends. With current theoretical knowledge, a star of this mass has two possible outcomes. 1) It erupts in a cataclysmic explosion as a supernova and then forms into a black hole or 2) If the mass is high enough, currently believed to be around 50 solar masses, it will form directly into a black hole without the supernova.

What happens when a white dwarf contracts and fusion begins?
When fusion ignites in a white dwarf there is, at first, no increase in volume to separate the fusing nuclei and the result is a runaway nuclear reaction ending in a massive explosion with two possible outcomes. For lower mass white dwarfs, the explosion will drive away the surrounding gasses, producing a nova. If, however, the addition of the gas pushes the white dwarf above 1.38 solar masses, the result will be a much more powerful explosion called a type Ia supernova, which will destroy the white dwarf.
Identify two possible results of interspecific competition?
the results maybe reduction in the number of either species or elimination from the competitors

What happens when you mix two gases?
- a mixture of gases is obtained - at a given temperature and a given ratio gas1/gas2 an explosion is possible
What happens when a supernova explosion occurs near a black hole?

This can result in the formation of an accretion disk around the black hole, leading to the release of a powerful burst of energy in the form of jets of high-energy particles and radiation.
Why can't you see two stars collide?
Mostly, because stars are SO far apart! However, we have seen two stars that are so close together that one is stealing mass right off of the other star. If two stars were to actually collide, they would cause an explosion very much like a supernova.
What two things can a supernova become?
A supernova (plural: supernovae or supernovas) is a stellar explosion that creates an extremely luminous object.Check the link given for more information.
The results of division is?
One possible answer: In arithmetic, the result of dividing two numbers is called the quotient.
