Chapter 2, Problem 40EAP
These questions may be answered individually in short-essay form or dis-cussed in groups, except where identified as group-only.
40. Shadow Phases. Many people incorrectly guess that the phases of the Moon are caused by Earth’s shadow falling on the Moon. How would you convince a friend that the phases of the Moon have nothing to do with Earth’s shadow? Describe the observa-tions you would use to show that Earth’s shadow isn’t the cause of phases.

- We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand.
