Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk(*) designates a quantitative problem, for which you should show all your work.
Low-Density PIanets. Only one planet in our solar system has a density less than, but many extrasolar planets do. Explain why in a few sentences. (Hints: Consider the densities of the Jovian planets in our solar system, given in Figure 6.1.)

- Using Appendix G, complete the following table that describes the characteristics of the Galilean moons of Jupiter, starting from Jupiter and moving outward in distance. Table A This system has often been described as a mini solar system. Why might this be so? If Jupiter were to represent the Sun and the Galilean moons represented planets, which moons could be considered more terrestrial in nature and which ones more like gas/ice giants? Why? (Hint: Use the values in your table to help explain your categorization.)arrow_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
- Why I got it wrong? Please help me to provide just few summary.arrow_forwardExplain the folling data regarding artificial gravity. Just explain why these formulas were needed to ultimately find the artificial gravity(4.26 m/s^2)arrow_forwardFiguring for Yourself. Always show your work.27. Calculate the wind speed at the edge of Neptune's Great Dark Spot, which was 10,000 kmin diameter and rotated in 17 days. (Hint: recall a circle circumference=2 x pie x radius).arrow_forward
- Calculate the density of Jupiter. Show your work. Is it more or less dense than Earth? Why?arrow_forwardPlease answer the question and subquestions completely! This is one whole question which has subquestions! According to the official Bartleby guidelines, each question can have up to two subquestions! Thank you! 1) A missile is launched upward with a speed that is half the escape speed. What height (in radii of Earth) will it reach? R/4 R/3 R/2 R 2R A) The weight of a 0.60 kg object at the surface of Planet V is 20 N. The radius of the planet is 4 x 10 6 m. Find the gravitational acceleration at a distance of 2 x 10 6 m from the surface of this planet. 8.9 m/s2 11 m/s2 13 m/s2 18 m/s2 B) Two masses are precisely 1 m apart from each other. The gravitational force each exerts on the other is exactly 1 N. If the masses are identical, what is each mass? 1.22 x 105 kg 1.34 x 1010 kg 2.50 x 105 kg 1.58 x 1010 kgarrow_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
- In 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_forwardPLEASE be clear in your answer since the last time I posted was incorrect and only answer part a, thanks.arrow_forwardWhat is Tidal Energy? What are two advantages associated with tidal energy? What are two disadvantages associated tidal energy? What kind of machinery/apparatus can we use to convert tidal energy into electricity?arrow_forward
