When a black hole of mass M1 merges with a black hole of mass M2, it creates a new black hole of mass M3. Do you expect M3 to be equal to, less than, or more than, the sum M1 + M2? Recall mass–energy equivalence and the fact that there is gravitational radiation emitted as they merge. Now look up the first LIGO discovery GW150914 and look up M1, M2, M3 for this discovery. Are you right?

A black hole is an object with mass, but no spatial extent. It truly is a particle. A black hole may form from a dead star. Such a black hole has a mass several times the mass of the Sun. Imagine a black hole whose mass is fifty-seven times the mass of the Sun. Would you expect the period of an object orbiting the black hole with a semimajor axis of 1 AU to have a period greater than, less...
In the figure to the right, M2 has more mass than
M1 and M1 has more mass than M3.
The questions refer to the magnitudes of tensions and weights.
There is friction between the horizontal plane and M2
().
M2 is observed to travel at a constant speed. Assume
that the pulleys are frictionless and have negligible
mass. SEE THE PHOTO BELLOW!!!
options are True, False, Greater, Than Less, Than, or Equal

Problem 4. Radiation from the black hole accretion disk.] In this problem you will find the temperature of an accretion disk surrounding the black hole, and the wavelength of maximal radiation from the disk. Note that the calculation is super-simplified - if you take more advanced astronomy courses, you will do the same calculation more carefully. In this problem 'BH' means black hole. We will consider the BH of mass equal to twenty solar masses MBH = 20 MSun. (a)...
Also how do you figure it out?

Now we consider a black hole of the same mass as the Sun: Mbh 2x 1030 kg. (a) (2 marks) Show that if you are launching a rocket with velocity v upwards from a pl M, you can only escape the planet's gravity if you start from a radius r > 2GM/ t of mass Hint: Use Newtonian mechanics. What if your rocket is acutally a beam of light? If we forget about relativity for a minute, we can put...

An overnight rainstorm has caused a major roadblock. Three
massive rocks of mass m1=598kg, m2=796kg and m3=311kg have blocked
a busy road. The city calls a local contractor to use a bulldozer
to clear the road. The bulldozer applies a constant force to m1 to
slide the rocks off the road. Assuming the road is a flat
frictionless surface and the rocks are all in contact, what force,
FA must be applied to m1 to slowly accelerate the group of...
A 6.05-kg black cat and her four black kittens, each with mass o.792 kg, sleep snuggled together on a mat on a cool night, with their bodies forming a hemisphere. Assume the hemisphere has a surface temperature of 27.9°c, an emissivity of 0.970, and a uniform density of 1046 kg/m (a) Find the radius of the hemisphere (b) Find the area of its curved surface. m2 (c) Find the radiated power emitted by the cats at their curved surface (d)...
