9. The location is set to Fairfax for today's date at noon. The next parts of the answer are written accordingly.
10. The Earth is tilted at an angle of 23.5 degrees with respect to the plane of the solar system. Hence, the sun is not always directly overhead at the equator. When the sun is directly overhead, the solar altitude is 90 degrees. This occurs at the equator during the vernal and autumnal equinoxes. At the Tropics of Cancer and Capricorn, the sun will have an altitude of 90 degrees during their respective summer solstices.
11. In the Northern Hemisphere, the sun always rises in the east and sets in the west. At noon, it looms in the middle of the horizon and directly south. That means when you're facing the sun at noon, walking directly toward it will take you south. Walking with the sun at your back means you're heading north.
12. Generally, the sunset occurs at 6-7 pm local time. Thus the sun sets approximately 6.5 hours after 12 pm.
13. Solar altitude is the angle of the sun relative to the Earth's horizon and is measured in degrees. The altitude is zero at sunrise and sunset, and can reach a maximum of 90 degrees (directly overhead) at noon at latitudes near the equator.
14. The sun always sets in the West. Hence I would face West to watch the sunset.
15. & 16. : One needs empirical data to answer these questions. One needs to observe these by being physically present at the location.
17. The Sun always rises in East & sets in West every day.
18. The first day of the Season of Summer, called SUMMER SOLSTICE: on this day (JUNE 21 in the northern hemisphere*) the Sun is farthest in the north and the daytime is the longest of the year.
