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:
0 m/sec
Explanation:
b/c they were at rest and initial means at rest ,at rest means 0 HOPE THIS HELPS
I would say false, violet has the highest frequency. <span />
We are given
damped harmonic oscillation force = k
mass = m
damping constant = b1
amplitude = a1
driving angular frequency = k/m
I think we asked for the amplitude of the force at different damping constant
The formula to use is
A = (F/ (√(k - m w²)² + (b² w²))
Simply substitute and solve for A in terms of a1
Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
