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.
Lucky to be Be Here? Considering the overall process of soar system formation, do you think formation of a planet like Earth was likely? Could random events in the early history of the solar system have prevented our being here today? What implications do your answers have for the possibility of finding planets with Earth-like conditions around other stars? Defend your opinions.

For a more clear response please answer on paper Thank you!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_forwardRead the following items carefully. State your assumptions if any. Show your COMPLETE solution and BOX your final answers. Keep your answers and solutions in 4 decimal places. > Initially, 100 milligrams of a new radioactive substance Tobium, named after its discoverer Sir Tobs, was discovered and collected from one of the moons of Jupiter. After 6 hours from collection, the mass decreased by 4%, If the rate of decay IS proportional to the amount of the substance present at time t, find the amount of Tobium remaining after 48 hours.arrow_forward
- 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?arrow_forwardAre the planets really lined up as we have them in this model? (Model is the image attatched). What is the minimum possible distance in AU between Mars and Earth? What is the maximum possible distance in AU between Mars and Eath? Show your work if possible. Thanks so much :)arrow_forwardPROBLEM SOLVING: Express your answer to the fourth decimal places. Show complete solution. Box your final answer. 1. A wooden object found in an Indian burial ground and subjected to radiocarbon dating. The decay rate associated with C-14 is 10 disintegrations per minute per gram carbon.

- As discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. 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? Reletive Numbers Relevant Numbers1 AU = 150,000,000 km = 1.5x108 kmEccentricity of Earth’s Orbit: 0.0167Radius of Earth: 6371 kmMass of Earth: 5.96x1024 kgRadius of the Moon: 1737 kmMass of Moon: 7.34x1022 kgRadius of Mars: 3390 kmMass of Mars: 6.4x1023 kgRadius of the Sun: R⦿=696,300 kmMass of the Sun: M⦿=2x1030…arrow_forwardDrag the moon to various locations in order to determine the quantitative effect of distance upon the gravitational force. Examine the effect of doubling, tripling and quadrupling the distance of separation (as measured from planet'scenter). Consider the planet'ssurface to be a distance of one Earth-radius (1 Rplanet). Use the table at the right to record data for whole-number multiples of Rplanet.Use your data to complete the following sentences.If the separation distancebetween the moonand the planetis ... a. ... increased by a factor of 2, then the Fgravis ______________ by a factor of _______.b. ... increased by a factor of 3, then the Fgravis ______________ by a factor of _______.c. ... increased by a factor of 4, then the Fgravis ______________ by a factor of _______arrow_forwardProcedure Table 11.1 presents Djup and Pday for the major Jovian satellites. First use these data and the equation above to calculate Jupiter’s mass in kilograms (kg). Enter your results in the table for each satellite. Next calculate the average Jupiter mass (Mjup, av) and enter the result in the table. Finally, calculate the percent difference (PD) using Mjup, av and the standard value for Jupiter’s mass (1.9 X 1027 kg). In the calculation of PD you can ignore 1027 because it will appear in both numerator and denominator. ________________________________________________________ Table 11.1 Calculated values for Jupiter’s Mass Satellite Djup Pday Mjup Io 2.95 1.77 Europa 4.69 3.55 Ganymede 7.50 7.15 Callisto 13.15 16.7 __________________________________________________________ Average Jupiter Mass = Percent Difference =arrow_forward

Please write your solution clearly and readable. Thank you.arrow_forwardCarbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.arrow_forward
