Q. Why do protons not repel each other in the nucleus?
1 Answer. Protons in nucleus no doubt are repelled by each other. But we know that an atom is stable. The reason for this is that the protons and the neutrons(together called nucleons) are attracted to each other by a strong for called nuclear force.
Q. Why do neutrons stick together?
Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (mesons), binding them together. Although the strong force overcomes electrostatic repulsion, protons do repel each other.

Q. What holds the electrons and the nucleus together?
The strong force is a force which attracts protons to protons, neutrons to neutrons, and protons and neutrons to each other. So the nucleus of an atom is held together by the strong force, while the electrons are held in the atom by the electric force.
Q. What does the stability of a nucleus depend on?
The stability of an atom depends on the ratio of its protons to its neutrons, as well as on whether it contains a “magic number” of neutrons or protons that would represent closed and filled quantum shells. These quantum shells correspond to energy levels within the shell model of the nucleus.
Q. Which force is responsible for holding the nucleus together by gluons?
Once within range, massless charged bosons called gluons transmit the strong force between quarks and keep them “glued” together. A tiny fraction of the strong force called the residual strong force acts between protons and neutrons.
Q. Does the nucleus attract electrons?
The protons have a positive charge the electrons have a negative charge and the neutrons are neutral. The electrons are attracted to the nucleus by the electrostatic force of attraction to the protons.
Q. What happens when two spiral galaxies collide quizlet Astro 7n?
when two spiral galaxies collide they form a elliptical galaxy. a spiral galaxy alone is neat and orderly, when two orderly galaxies collide they form a messy tangled galaxy which is an elliptical galaxy. This can cause galaxies to become distorted or even rip apart.
Q. What happens when two spiral galaxies collide?
A: When two spiral galaxies collide, gravity is the main force that comes into play. As the galaxies approach each other, gravitational forces start to pull the stars, gas, and dust of the spiral arms out of their original orbits. Elliptical galaxies are also known for their dearth of star-forming material.
Q. Which of the following could happen when two galaxies collide quizlet?
The clouds of gas in the galaxies DO collide. The collisions can cause bursts of star formation, excess supernovae, new neutron stars and black holes, and other high-energy events.
Q. What happens when two spiral galaxies collide Astro?
When the galaxies collide, it causes vast clouds of hydrogen to collect and become compressed, which can trigger a series of gravitational collapses. A galaxy collision also causes a galaxy to age prematurely, since much of its gas is converted into stars.
Q. Does the Milky Way show evidence of past collisions?
Astronomers have found stars dating from a long-ago collision between the Milky Way and another galaxy. The crash helps to explain why the Milky Way looks the way it does. “It’s interesting because we can finally see what the history of the Milky Way is.”
Q. What happens to Earth if galaxies collide?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have …
Q. Which type of Protogalactic cloud is most likely to form a spiral galaxy?
2) A protogalactic cloud with slow star formation is more likely to form a spiral galaxy than an elliptical galaxy. 3) A protogalactic cloud with very little angular momentum is more likely to form an elliptical galaxy than a spiral galaxy.
Q. What is the source of energy for active galaxies?
The energy source of active galaxies is the steady accretion of matter onto a supermassive Black Hole. Gas settles into an accretion disk. The hot inner parts of the disk shine brightly, especially at X-rays.
Q. What are 3 characteristics of a elliptical galaxy?
There are four distinguishing characteristics of the ellipticals: (a) they have much more random star motion than orderly rotational motion (star orbits are aligned in a wide range of angles and have a wide range of eccentricities); (b) they have very little dust and gas left between the stars; (c) this means that they …
Q. Why are most stars not destroyed in a galaxy collision?
Despite the Andromeda Galaxy containing about 1 trillion stars and the Milky Way containing about 300 billion, the chance of even two stars colliding is negligible because of the huge distances between them.
Q. What will happen when the Milky Way galaxy collides with dwarf galaxies?
The Milky Way Colliding with Dwarf Galaxies It’s been pulled apart as it orbits the Milky Way. Now it’s stream of gas and dust surrounding the Milky Way. Another dwarf galaxy surrounding the Milky Way is the Sagittarius Dwarf.
Q. Has the Milky Way ever collided with another galaxy?
At least a dozen times over the last 12 billion years, the Milky Way collided with a neighboring galaxy and devoured it, swallowing up that neighbor’s stars and mixing them into an ever-growing stew of pilfered suns.
Q. Will we die when Andromeda collides?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy.
Q. How fast is the Milky Way moving through space?
1.3 million miles per hour
Q. Is the Milky Way moving through space?
The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. Even at this rapid speed, the solar system would take about 230 million years to travel all the way around the Milky Way.
