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.

4. Find the magnifying power (M) and the length (L) of a simple telescope with 30-inches focal length of the objective and 2 inches focal length of the eyepiece.…
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
