Textbook Question
Chapter 13, Problem 56P
Consider Figure 13.23 in Tidal Forces. This diagram represents the tidal forces for spring tides. Sketch a similar diagram for neap tides. (Hint: For simplicity, imagine that the Sun and the Moon contribute equally. Your diagram would be the vector sum of two force fields (as in Figure 13.23), reduced by a factor of two, and superimposed at right angles.)

Exercise 7.2
49. Physical Science Because of the forces caused by its rotation, Earth is an oblate
ellipsoid rather than a sphere. The equatorial radius is 6378 kilometers and the polar
radius is 6357 kilometeres. Find an equation of the ellipsoid. (Assume that the center
of Earth is at the origin and that the trace formed by the plane z=0 corresponds to
the equator.)
Equatorial
radius = 6378 km
Polar
radius = 6357 km

- You can invent your own measured values or just use the d, t, and theta to derive an equation for gravity.arrow_forwardYou can determine the radius of a planet by measuring the change in the flux coming from the star (i.e. the transit method). If the radius of the planet increases, the overall flux decreases, but what happens to the change in the flux Group of answer choices Increases Decreases Stays constantarrow_forwardA rotation rate, or frequency, of 500 nHz corresponds to a rotation period of 23 days—it takes 23 days for material to follow one complete circle around the Sun. Furthermore, the frequency and period are inversely proportional to one another: if one is doubled, the other is halved. Given these facts, what is the approximate rotation period (in days) for equatorial material at the Sun's surface? (Use your answer to the previous question as the rotation rate.)arrow_forward
