Textbook Question
Chapter 4, Problem 5VSC
Use the following questions to check your understanding of some of the many types of visual information used in astronomy. For additional practice, try the Chapter 4 Visual Quiz at MasteringAsrrononry®.
The figure above, based on figure 4.24, shows how the Moon causes tides on Earth. Note that the North Pole is in the center of the diagram, so the numbers 1 through 4 label points along Earth's equator.
5. The light blue ellipse represents tidal bulges. In what way are these bulges drawn inaccurately?
a. There should be only one bulge rather than two.
b. They should be aligned with the Sun rather than the Moon.
c. They should be much smaller compared to Earth.
d. They should be more pointy in shape.

Use the program to answer the following questions.
1. A planet and its moon are shown in the simulation window. Click and drag the
moon to various positions about the planet and observe the gravitational force
vector. In the diagram below, draw a force vector (arrow with arrowhead) to
depict the direction and relative magnitude of the force acting upon the moon at
the designated locations. Note: the size of the arrow should be representative of
the strength of the force.
Delay time for communication between GEO satellites and Earth.
Use the relationship between distance (d), time (t) and speed (v),
d = vt
to repeat the calculation we did in class, but this time using the English units. Use the fact that
GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is
1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.) You
may want to write this calculation on paper and insert a photo here.

- 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?
