explain each physics formula by saying what each variable means/stands for and explain the formula as a whole, please.
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.)
. What is a system and what is the universe, and how are they related to the 2nd Law ofThermodynamics? PLEASE type out and not write on a paper I need to understand this

- Read the following questions carefully and answer the problems using GRESA. 1. Assuming that the field of view is flat, what is the resultant vector (yellow line) of an observer pointing his telescope starting at the Andromeda galaxy, then moving 62 units 27° S of W to Jupiter, then finally moving to Saturn 17 units 72° S of W. Express your magnitude to the nearest hundredths units, and the angle to the nearest hundredths °, following the standard cartesian plane coordinate system.arrow_forwardOn this situation for science I do not understand. Under the write section is what we're supposed to be including. So down below I will show you what it is asking, and what it wants me to write 2 paragraphs about can you please help me with a deep explanation, because I need help asap because it's due at 11:59 tonight.arrow_forwardSee 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_forward
- For the graph shown above, a) what quantity would you label the y-axis with if the distance is between galaxies and the Earth? Explain your answer. Think through what we know is happening, motion-wise, out there in the galaxy. b) Also explain why you think there are dots and a solid line, on the graph.arrow_forwardDISCLAIMER : THIS IS MY ASSIGNMENT :)) ,, ALSO PLEASE REFER ON THE REMINDERS.. OUR SUBJECT IS GENERAL PHYSICS 1. AND PLEASE PUT A LABEL ASAP BECAUSE IT'S CONFUSING IF THERE'S NO LABEL ( ex : answer in letter b : )arrow_forwardPlease provide steps for how you got the solution to the problem provided below, I am trying to understand the problem, not just see an answer. Thank you so much. A space ship warp engine has enough energy to perform two warp jumps going between star systems (i.e., the warp battery has 2 units of charge). The ship can operate in two modes: survey the current system or charge battery. On a given day the ship will complete the survey of the current system with probability 0.24. Then, if battery has capacity, it will move to a new system, consuming 1 unit of charge. If the battery is empty, the ship will switch to the charging mode. In the charging mode, the ship will recover 1 unit of charge on a given day with probability 0.95. The ship will stay in the charging mode until the battery is full. Model the behavior of the ship as a Markov chain.arrow_forward
- 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?arrow_forwardPLEASE be clear in your answer since the last time I posted was incorrect, and only answer part b, thanks.arrow_forwardpls helppp, I'll rate if you get the correct answer.

- The 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_forwardState 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!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. Ex: Use 1/2arrow_forward
