 1<span lang="en-us">. Name the astronomer whose observations of the motions of 
	planets led to the discovery that planetary motion obeys mathematical laws.&nbsp; 
	(one word) <input type="text" name="astronomer" size="10"></span></p>
<p>
 <span lang="en-us">2.&nbsp; The diagram on p. 177 of P<sup>3</sup> shows the 
	Earth during two different parts of its orbit around the Sun. The shaded 
	areas of the diagram represent the areas &quot;swept out&quot; by the Earth during 
	those two parts of the orbit. In the diagram, those two areas are equal. If 
	the time for the Earth to sweep out the area that is closer to the Sun is 
	one month, then the time for the Earth to sweep out the area that is farther 
	from the Sun must be (choose one):</span></p>

	than one month</span></p>

	the Earth during one full elliptical orbit (yes or no) ?
	<input type="text" name="net_work" size="5"></span></p>
<p>
 <span lang="en-us">4. Suppose two different satellites orbit a mass, as shown 
	for example in the diagram on p. 180 of P<sup>3</sup> (ignore the numbers in 
	that example, just look at the diagram). Let's say that the radius of the 
	larger orbit in the diagram is 4 times greater than the radius of the 
	smaller orbit. According to Kepler's Third Law, how many times greater (or 
	smaller) is the period of the satellite with the larger orbit ? Enter a 
	numerical value in the first box, and either &quot;greater&quot; or &quot;smaller&quot; in the 
	second box.&nbsp; </span></p>

	astronomers. (one word)&nbsp;

 <span lang="en-us">9. The period of a satellite in a near-Earth orbit is

<p>
 <span lang="en-us">12. Name the scientist who first conceived the idea of a
