PLEASE be clear in your answer since the last time I posted was incorrect, and only answer part b, thanks.
See the screenshot uploaded. Answer in a step-by-step format, add diagrams, and detailed side notes for a better understanding. For a more clear response please answer on paper Thank you!
Think of our Milky Way Galaxy as a flat circular disk of diameter 100,000 light-years. Suppose we are one of 1000 civilizations, randomly distributed through the disk, interested in communicating via radio waves. How far away in light years would the nearest such civilization be from us on average? Show your working. (Hint: Begin by calculating the area of the disk. Find the area of one of a 1,000 squares. Consider the separation of the centres of two adjacent squares.)

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.

- In Diameters of Stars, the relative diameters of the two stars in the Sirius system were determined. Let’s use this value to explore other aspects of this system. This will be done through several steps, each in its own exercise. Assume the temperature of the Sun is 5800 K, and the temperature of Sirius A, the larger star of the binary, is 10,000 K. The luminosity of Sirius A can be found in Appendix J, and is given as about 23 times that of the Sun. Using the values provided, calculate the radius of Sirius A relative to that of the Sun.arrow_forwardIf the orbital velocity of the Earth in its orbit is 30 km/s, then what is the maximum Doppler shift you expect to see for the Hα absorption line at 656.3 nm?

How many times farther from the Sun is it, when compared with Earth? B) Communications with the spacecraft Alpha using radio waves require 2000 years for the round trip (there and back). This implies that Alpha is how many light years away from Earth?arrow_forward
