We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you.
Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)?
The actual diameter of Mercury is 4879 km
The Sun's diameter is 1392000 km
If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be:
30cm1392000km
Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer.
This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…

- Procedure 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_forwardRadiocarbon dating is the most common and important absolute dating technique in archaeology. The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below. 6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon. 7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages? 8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC.

- Impact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c.
