Using Kepler's 3rd law solve the following problem. Show your work and highlight your answer.
In a distant star system there are many inhabitable planets. One of these planets is named Qomar. Qomar is 3.2 AU's from its star and takes 6.5 Earth years to go around its star once. There is another planet in the same star system called Ferenginar. Ferenginar is 0.9 AUs from the star. What is the length of a Ferengi year (on Ferenginar) in terms of Earth years?

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)

- Please do not give solution in image formate thanku Q: You’ve just discovered another new X-ray binary, which we will call Hyp-X2 (“Hyp” for hypothetical). The system Hyp-X2 contains a bright, G2 main-sequence star orbiting an unseen companion. The separation of the stars is estimated to be 12 million kilometers, and the orbital period of the visible star is 5 days. Use Newton’s version of Kepler’s third law to calculate the sum of the masses of the two stars in the system. a)Express your answer in kilograms to two significant figures. b) Give your answer from the previous part in solar masses. ( Msun= 2.0 x 10 /30 kg). Express your answer as a multiple of sun’s mass to two significant figures. C) Determine the mass of the unseen companion. ( Hint: A G2 main-sequence star has a mass of 1 Msun.) Express your answer as a multiple of sun’s mass to two significant figures.

Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?
