Using MBH
=
6.6 × 10 Mo, calculate the below.
a. Find radius of the Schwarzschild sphere (Schwarzschild radius Rs). You
can calculated from the appropriate formula or just use the fact that for
an object of 1 solar mass Rs = 3 km.
b. Express Rs in km, in AU, in parsecs.
c. Using the distance to M87 and your result above, find angular radius of
the SMBH (Schwarzschild radius). Express it in arcseconds (") and micro-
arcseconds (pas)
d. Take the radius of Pluto's orbit equal to 40 AU and find its angular size
(in micro-arcseconds, pas) at the distance of M87.
Write a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below.
For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer.
hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.
State the definition for a parsec, and derive its value in terms of As- tronomical Units. Convert your answer for the value of the distance of a parsec in Astronomical Units into light years. Be sure to include a large and clearly labeled diagram showing how you arrived at your conclusions. Be sure to show all work!

- Which of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices Most M stars end up as neutron stars or black holes. The lifetime of M stars is longer than the age of the universe. Most M stars are located near the edge of the universe, beyond the visible horizon. Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion. White dwarfs are too dim to be observed with currently available techniques.arrow_forwardThe law of conservation of energy states that energy can be converted from one form to another but cannot be created or destroyed. Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At least one of your scenarios should be at the molecular level. Would the implications be positive? Negative? Explain.arrow_forwardChoose the correct statements from the following list referring to white dwarfs. (Give ALL correct answers, i.e., B, AC, BCD...) A) The pressure that balances gravity in a white dwarf is called degenerate electron pressure. B) The power source of white dwarfs is left-over heat. C) White dwarfs cool slowly because they are small and eventually fade-out to become black dwarfs. D) White dwarfs with mass greater than 1.4 times the Sun's mass cannot exist. E) Stars with a mass like the Sun will end up as a white dwarf star. F) White dwarfs are less dense than red giants. G) White dwarfs are the coolest main sequence stars.arrow_forward
