A superheated cloud of gas and dust swirling around a massive object (usually a black hole or neutron star) is called an accretion disk. The correct option is c.
<h3>What is accretion disk?</h3>
Accretion disk is a heavy object surrounded by flow of gas, plasma, dust, or particles. The materials surrounding the heavy object orbiting in the gravitational field of the object that loses energy and angular momentum as it slowly spirals inward.
This cloud can reach incredible speeds and temperatures as gravity causes it to build up more and more friction, eventually releasing x rays.
Thus, accretion disk is a superheated cloud of gas and dust swirling around a massive object.

Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
Answer:
So, if the sphere has net amount of charge on it, such that the test charge will experience its intensity in the given region of influence. As, the charge particles size plays a very important role in this regards, as the total distribution of the net charge occurs on the surface of the sphere.
So, we have the following formula in order to make the calculations and have the results, which is as follows:
- E=F/q, (while "F" is the net amount of force applied by the charged body when the test charge,q is placed in its field)
- And if we analyze the Gauss's law we have, Ф=q/∈,
- While, we can obtain the required results by putting all the data into the following equation,as follows:
- E=kq/r².
Because they know physics :)
higher amplitude => higher potential energy => more to transform into kinetic energy => higher speed => higher range (distance)
Answer:
Heat capacity is the amount of heat required to raise the temperature of an object by 1oC. The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1oC.
