A sample from a meteorite that landed on Earth has been analyzed, and the result shows that out of every 1,000 nuclei of potassium-40 originally in the meteorite, only 125 are
still present, meaning they have not yet decayed. How old is the meteorite (in yr)? (Hint: See the figure below.) (Note: The half-life of potassium-40 is 1.3 billion years.)

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_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

The Los Angeles area experiences many earthquakes. Suppose Los Angeles experienced an earthquake that measured a magnitude of 6.9 on the Richter scale. Suppose that Los Angeles experienced another earthquake years later, which measured 5.2 on the Richter scale. Compare the intensities of the two earthquakes. (Round your answer to the nearest integer.) The intensity of the earlier earthquake in Los Angeles was about times the intensity of the later earthquake.arrow_forward
- Hellas Planitia includes the word "planitia" which is the latin word for "plain" in its name. The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that. The most probable reason for this discrepancy in its name is because: a. It is a simple naming error that for some reason has so far escaped correction. b. There is a disagreement among astronomers about the true nature of Hellas Planitia. c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes. d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.arrow_forwardHow many impacts would you expect to strike a 100m2 region in one hour during Earth’s formation, assuming that Earth grew to its present size in 10 million years from particles averaging 100 grams each?

We think the irons are from the cores, the stony-irons are from the interfaces between mantles and cores, and the stones are from the mantles of their differentiated parent bodies. If these parent bodies were like Earth, what fraction of the meteorites would you expect to consist of irons, stony-irons, and stones? Is this consistent with the observed numbers of each? (Hint: You will need to look up what percent of the volume of Earth is taken up by its core, mantle, and crust.)arrow_forward
