According to Newton's law of between every pair of objects
universal gravitation, gravity acts Correct:
to Newton’s law of universal gravitation
produce a force _____. states that
gravity acts between every pair of objects.
The force of gravity is ____ if two greater
objects are closer. Correct:
Newton’s law of universal gravitation says
that the
force of gravity between objects is
proportional to
the product of their masses.
The force of gravity is ____ if the greater
mass Correct:
of either object is greater. Newton’s law of universal gravitation says
that the
force of gravity between objects is
inversely
proportional to the square of the distance
between
the masses.
,The force of gravity _______. is always attractive
Correct:
Gravity never causes objects to repel each
other.
Suppose some region of space Gravity would cause matter to attract and
happened to have a greater tend to
density be pulled toward regions where there is
of matter than another. Which of already
these describes the expected more matter.
effect Correct:
of gravity acting on matter in the Gravity pulls objects toward each other.
early universe?
The atomic number of an element larger
is Correct:
the number of protons it has in its As the diagram illustrates, the process of
nucleus. The fewer protons an fusing
atom small nuclei together forms larger nuclei.
has, the smaller the nucleus is.
During nuclear fusion, the nuclei of
small atoms, such as hydrogen,
fuse
together. This results in the
release of
energy and the formation of
elements with __________ nuclei.
, Nuclear fusion is the process that greater
produces energy in stars, including Correct:
Earth's sun. Gravity is a key force Joining the nuclei together produces a
in nucleus with
beginning nuclear fusion in a star. more protons and neutrons than each
Fusion can begin only when the original
gases have condensed enough to nucleus, and therefore a greater atomic
increase their temperature and mass.
pressure to the point that the
hydrogen atoms can be forced to
fuse together.The new elements
have
greater atomic number and
___________
atomic mass.
Nuclear fusion: A process that occurs when hydrogen and
other
small nuclei fuse together to form larger
nuclei,
releasing large amounts of energy in the
process
Star: A celestial body that is held together by its
own
gravity and that releases visible light and
other
forms of radiant energy generated by
nuclear
fusion
When astronomers refer to the our own galaxy
Milky Correct:
Way, they mean __________. Earth is in the Milky Way galaxy
