Homework Answers
Black hole act as a point charge source so it can absorb the charge particle.
When it absorbs mass, it's event horizon gets expanded.
When it absorbed a spinning object it's shape become obelate spheroid.

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)...

What do you think happens to the value of the Law Enforcement Oath of Honor when the very ones that we trust to serve and protect us, becomes the very ones that we fear the most? Furthermore, how do you think Americans look at police departments in North America after incidents of police misconduct, much like in New Orleans, and other cities in this country such as Los Angeles, New York, New Orleans and Chicago, just to name a few.
