The correct option is B. twice.

If a black hole suddenly doubled in mass, the event horizon would become <u>twice</u> its original size.

What is a blackhole?

In space, a black hole is a location where gravity pulls so strongly that even light cannot escape. Because stuff can fit into such a small space thanks to gravity, this is a strength of our universe. When a star dies, things like this may occur.

No light can escape, so people cannot perceive black holes. They are invisible. The search for black holes can be aided by space telescopes equipped with exceptional instruments. The special equipment can detect how stars that are very close to black holes behave differently from other stars.

What is event horizon?

The border around a black hole from which nothing (not even light) can escape is known as the "event horizon." In other words, an object inside the event horizon has an escape velocity that is faster than light. The name is derived from the fact that nothing occurring inside it can be seen; it is an invisible horizon. As a result, the event horizon successfully conceals the singularity at the center of the black hole, which is a relief for astrophysicists who are troubled by how the laws of physics break down at such a location.

The atmosphere has many roles, including:
monitta
There are five layers of the atmosphere and these are; troposphere, stratosphere, mesosphere, thermosphere and exosphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure. </span>

Answer:

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
