Questions:
1. Do planets that are farther from the sun travel faster than those which are
nearer?
2. How does the distance from the sun of a planet affect the planet's orbital
velocity?
3. Suppose a hypothetical planet-Planet X, located between Mars and
Jupiter, has been discovered. How would the mean orbital velocity of
Planet X compare to that of Earth and Saturn?
Planet X is four times as massive as its moon Y and their centers are separated by 100,000 km. Relative to the center of planet X, about what point (the center of mass) does the planet-moon system orbit?
A) d= 12,000 km from planet X’s center
B) d= 16,000 km from planet X’s center
C) d= 20,000 km from planet X’s center
D) d= 24,000 km from planet X’s center
E) d= 48,000 km from planet X’s center
Suppose an asteroid has a tiny moon orbiting around it
(which does occur). If the moon is 1.1 km wide, is 142
km from the center of the asteroid (which is 36 km in
diameter), and assuming the moon has a circular orbit
around the asteroid of period 36 hours, what is the
mass of the asteroid?
m =
kg [Note: Use exponential notation
for your answer with a format "9.99E12" for 9.99 x
1012.]
What would the radius of the orbit of the same tiny
moon be if it had an orbital period of 50.9 hours? Give
your answer in km:
R =
km
What is the density of the asteroid? Recall that density
is mass per unit volume. The volume of the asteroid
can be calculated based on its diameter (assume it is
spherical in shape).
