Answer:
Schwarzschild radius
Explanation:
A black hole is defined as that object from which light cannot escape form the surface of the object because object is very small an very dense. There are numerous black hole sin the universe.
Black hole is well understood by the concept of "escape velocity". Escape velocity is the speed of any object to break the gravitational pull from another object.
Escape velocity depends on mass of the object and the distance from the center of the object ( how big or small the object is ). If the object is smaller or more denser, than the escape velocity is more. If we squeeze our earth to a radius of about 9 mm sphere, then the escape velocity of any object becomes equal to the velocity of light.
And the radius of any object which have an escape velocity which is same as the velocity of light is known as the 'Schwarzschild radius'.
Any object which is smaller than the "Schwarzschild radius' has an escape velocity more than the speed of light and is termed as a black hole.
Thus, any object which is squeezed beyond the Schwarzschild radius be becomes a black hole.
Answer:
To divide the charge q into two parts such that they experience maximum electrostatic repulsion, the charges should be equal in magnitude and opposite in sign. In other words, the charge q should be divided into two equal charges of -q/2 and +q/2. This arrangement will result in the maximum electrostatic repulsion between the charges, as like charges repel each other.

Answer:
chlorine is a non-metal.
Explanation:
a chlorine atom has 7 electrons in its outer shell. chlorine is in group 7 of the periodic table. two chlorine atoms will each share one electron to get a full outer shell and form a stable cl2 molecule.
B.the amount of space that matter ocupies
C.how fast the particles are moving
D.amount of massin a certain place
Neon gas
Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood
Answer:
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.
Answer:
A) wood, water, neon gas
Explanation:
wood, water, neon gas.
The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.
tell me if im wrong .... hope this helps :)
