PHY 111 EXAM 1 FINAL STUDY GUIDE
ACCURATE
4.6 Hours - ANSWERSSunlight takes 8.4 minutes to get from the Sun to Earth. When
NASA's New Horizons Spacecraft passed Pluto in 2016, it was 33 AU from Earth. How
long did it take for its transmitted images of Pluto to arrive at Earth?
The seasons would be more extreme, because the Sun's rays would be more direct in
summer, and less direct in winter. - ANSWERSIf the Earth's rotation axis were tilted by
45 degrees instead of 23.5 degrees, what are some of the implications, and why?
our evening view of space depends on where Earth is located in its orbit around the Sun
- ANSWERSIn any particular place on Earth, certain constellations are visible in the
evening only at certain times of the year because...
over many days or weeks, the planet moves westward relative to the stars, rather than
the usual eastward relative to the stars - ANSWERSDuring the time that a planet is in its
period of apparent retrograde motion,
The tilt of Earth's axis causes different portions of the Earth to receive more direct
sunlight and more hours of sunlight at different times of year. - ANSWERSWhich of the
following best describes why we have seasons on Earth?
3,600 - ANSWERSHow many arcseconds are in one degree?
It appears very near the north celestial pole. - ANSWERSWhat makes the North Star,
Polaris, special?
a useful illusion used to map the stars and other objects in the sky - ANSWERSThe
celestial sphere is...
full - ANSWERSIf the Moon is setting at 6 A.M., the phase of the Moon must be
Solar eclipses would be much rarer. Total solar eclipses would last much longer. -
ANSWERSWhat effect or effects would be most significant if the Moon's orbital plane
were exactly the same as the ecliptic plane, the plane of the Earth's orbit?
The Moon's umbra must touch the area where you are located. - ANSWERSIn addition
to the conditions required for any solar eclipse, what must also be true in order for you
to observe a total solar eclipse?
