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.

Problem 2. Planetary Body Composition: Density (Links to an external site.) of the Earth (Palen, et. al., 1st Edition, Chapter 6, problem 70)
Earth’s mean (Links to an external site.) radius is 6,378 km and its mass is 5.97 x 1024 kg.
CALCULATE Earth’s average (Links to an external site.) density. SHOW YOUR WORK. DO NOT LOOK UP THIS VALUE!
The average density of Earth’s crust is 2,600 kg/m3. What does this tell you about Earth’s interior?
Write a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below.
For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer.
hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.

- 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…arrow_forwardLet's use Kepler's laws for the inner planets.

- 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?

- The Earth is about 12800 (1.28 x 104) km in diameter. If you drew the Earth to scale on your model (model is attatched here) how many centimeters across would the dot measure? Show your work here: Scaled diameter of Earth on model = _____________ cm. Based on this calculation, is your model’s scale a good one for showing the relative sizes of the planets?

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.
