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:
B. 0 degrees
Explanation:
The magnetic flux through a certain area enclosed by a loop of wire immersed in a region with magnetic field is given by:
where
B is the strength of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of the magnetic field and the direction of the normal to the coil
From the equation above, we see that the magnetic flux is maximum when
So when the field is parallel to the normal to the coil (so, when it is perpendicular to the coil), therefore when:
So, the correct option is
B. 0 degrees
Answer:
glycolysis is the answer to the question
Answer:
Walking’ - If a handball player takes more than three steps without dribbling (bouncing the ball) or holds the ball for more than 3 seconds without bouncing it, shooting or passing, then that is deemed ‘walking' and possession is lost.
'Double dribble’ - Handball players cannot receive the ball and bounce it, then hold the ball, and bounce it again. This is termed ‘double dribble’ and is against the rules.

A graph of real speed can have a section that's as steep as you want,
but it can never be a perfectly vertical section.
Any vertical line on a graph, even it it's only a tiny tiny section, means
that at that moment in time, the speed had many different values.
It also means that the speed took no time to change from one value to
another, and THAT would mean infinite acceleration.
