14. Based on what the nebular theory tells us about the formation of our own solar system, what does the theory predict for the possibility of other planetary systems?
Group of answer choices
Other planetary systems should be identical to our own.
Planetary systems should be very rare.
Most stars should have one or two planets, but not more.
Planetary systems should be common.
15. Which of the following statements best describes the accomplishments of these three people?
Group of answer choices
Tycho collected the data, Kepler provided the model in the form of laws, Newton explained the model in terms of gravity.

Question #4:
According to the nebular theory, which planet is most likely to be
gaseous rather than rocky?
A. Venus, because it is the warmest planet and so is more likely
to be gaseous
B. Mercury, because planets closer to the solar nebula are more
likely to be made of gas, like the nebula
C. Earth, because the atmosphere consists of nitrogen, oxygen,
and other gases, so it is a gaseous planet
D. Neptune, because as the planets get farther from the solar
nebula, their composition is more icy and gaseous

TRUE or FALSE
1. A spacecraft must attain a speed of 11.2 km/s to leave the Earth's surface.
2. It is easier to leave the surface of Jupiter than Earth.
3. Escape velocity is affected by the planet's mass.
4. Mars has smaller escape velocity than Venus and Earth because it is farther
from the sun.
5. The escape velocity of a planet is not affected by the sun's warping of space-
time.
