Drag 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 _______
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?
For problems requiring calculations, show the equation you will use to solve, your work, your
answer, and correct units. E F=ma

- Let's use Kepler's laws for the inner planets. Use the following distances from the sun to calculate the orbital period for each of these planets. Express your answer in terms of Earth years to two significant figures. Answer for the highlighted planet in each question. Note: Use Kepler's law directly. Don't just Google the answers, as they will be a little bit different. When you have calculated them, only submit the value for Earth.

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

- 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?
