Textbook Question
Chapter 10, Problem 10QQ
Choose the best answer to each of the following. Explain your reasoning.
What makes astronomers think that Cygnus x-1 contains a black hole? (a) We can directly observe that one member of the system emits no light. (b) The unseen object orbited by a luminous star is too massive to be a neutron star. (c) The strong x-ray emission from the system means it must contain a black hole.

PLEASE be clear in your answer since the last time I posted was incorrect, and only answer part b, thanks.
Why I got it wrong? Please help me to provide just few summary.
Please answer the following
A) Suppose an object takes 1000 years to orbit the Sun. 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?

- 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!arrow_forwardPlease answer the question and its subquestions entirely! This is one question with two subquestions. According to the official Bartleby guidelines, I am alowed to have up to two subquestion! 1) When an ice-skater spins and increases her rotation rate by pulling her arms and leg in, what happens to her kinetic energy? It stays the same. It increases. It decreases. a) A 0.400 kg mass, sitting on a horizontal frictionless surface, is attached to the end of a 0.750 m string. It is whirled around in a circular horizontal path. If the maximum tension that the string can withstand is 450 N, then what maximum velocity can the mass have if the string is not to break? 375 m/s 22.4 m/s 19.4 m/s 29.0 m/s b) A grinding wheel with a moment of inertia of 2 kg-m 2 has a 2.50 N-m torque applied to it. What is its final kinetic energy 10 seconds after starting from rest? 312 J 237 J 156 J 106 Jarrow_forwardIn the best case scenario for a gravity boost, a spacecraft approaches a planet very closely and does a U-turn around it, heading back exactly in the direction it came. If the spacecraft was initially going to the right with a speed of 5 km/s, and the planet was going to the left at a speed of 13 km/s, what would be the fastest the spacecraft could be going after the U-turn, in km/s? Be clear and show all your work.arrow_forward
- Hello, part D was incorrect, and where does the six come from?? I confused on reading the grapharrow_forwardpls helppp, I'll rate if you get the correct answer. NOTE: please put all the answers w/o rounding off, even if the answer is long. Ex. 1234.5678910 Narrow_forwardplease answer all the parts, and double and triple check your answers, previous tutors got it wrong, there are 4 total parts attached as 2 screenshotsarrow_forward
- Please explain in steps how you solved this and the question boxes on each side of the answer gives you choices to choose N, S, E or W.arrow_forwardSuppose that the Earth grew to its present size in 1 million years through the accretion of particles averaging 0.1 kg each. On average how many particles did the Earth capture each second? (Assume that the Earth's mass is 6 x 1024 kg.) Please show all work.arrow_forwardPlease show your solution and at the same time BOX the answers that corresponds to each blank on the question. Make sure to fill all the blanks. Thank you. STRICKLY FOLLOW THIS: Calculated Answers Express your answers without rounding off and without scientific notation unless instructed otherwise. Multiple Blanks Write powers or subscript as is. Ex: Use b2 if you mean b2 or b2 Spell out Greek letters. Ex: Use pi if you mean greek letter pi Write answers without spaces. Ex: Use 2epsilon0r3 if you mean 3e0r3 Write fractions with a slash.

- Which if any of these students do you agree with ? Please explain your reasoning. For the first onearrow_forwardThink 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.)arrow_forwardPlease explain in full detail as I am trying to understand this concept! thank you! a. Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture. b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec. c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.arrow_forward
