Question

part b: which two details from the text best support the answers to part a?
a. \orbits come in different shapes. all orbits are elliptical, which means they
are an ellipse, similar to an oval.\ (paragraph 3)
b. \the closest point a satellite comes to earth is called its perigee. the
farthest point is the apogee.\ (paragraph 4)
c. \the time it takes a satellite to make one full orbit is called its period. for
example, earth has an orbital period of one year.\ (paragraph 4)
d. \a constant tug-of-war takes place between the satellites tendency to
move in a straight line, or momentum, and the tug of gravity pulling the
satellite back.\ (paragraph 5)
e. \if the forward momentum of one object is too great, it will speed past and
not enter into orbit. if momentum is too small, the object will be pulled
down and crash.\ (paragraph 6)
f. \the international space station is in low earth orbit, or leo. leo is the
first 100 to 200 miles (161 to 322 km) of space.\ (paragraph 7)

Explanation:

To answer this question, we need to find two details from the text that support the idea that orbits are elliptical (as stated in Part A). Option A directly mentions that orbits are an ellipse (similar to an oval), which is a key characteristic of elliptical orbits. Option B further elaborates on the components of an elliptical orbit (perigee - closest point and apogee - farthest point), reinforcing the elliptical nature. Other options (C - period, D - movement due to gravity and momentum, E - orbit entry condition, F - LEO details) do not directly relate to the shape (elliptical) of orbits.

Answer:

A. "Orbits come in different shapes. All orbits are elliptical, which means they are an ellipse, similar to an oval." (Paragraph 3)
B. "The closest point a satellite comes to Earth is called its perigee. The farthest point is the apogee." (Paragraph 4)
