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 MasteringAstronomy®.
The figure represents how the Moon causes tides on Earth; the diagram looks down from above the North Pole, so the numbers I through 4 label points along Earth’s equator.
5. The light blue region 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.

- You're on an interplanetary mission, in an orbit around the Sun. Suppose you make a maneuver that brings your perihelion in closer to the Sun but leaves your aphelion unchanged. Then you must have Question 2 options: sped up at perihelion sped up at aphelion slowed down at perihelion slowed down at aphelionarrow_forwardThe force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees.
