The following diagrams are the same as those from Parts A and B. This time, rank the planets from left to right based on their average orbital speed, from fastest to slowest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to show this equality. (Distances are to scale, but planet and star sizes are not.)

Each of the following diagrams shows a planet orbiting a star. Each diagram is labeled with the planet's mass (in Earth masses) and its average orbital distance (in AU). Assume that all four stars are identical. Use Kepler's third law to rank the planets from left to right based on their orbital periods, from longest to shortest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to...

Part F Consider again the diagrams from Parts D and E, which are repeated here. Again, imagine that you observed the asteroid as it traveled for one week, starting from each of the positions shown. This time, rank the positions (A-D) from left to right based on how fast the asteroid is moving at each position Rank from fastest to slowest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top...

Part D Each of the four diagrams below represents the orbit of the same asteroid, but each one shows it in a different position along its orbit of the Sun. Imagine that you observed the asteroid as it traveled for one week, starting from each of the positions shown. Rank the positions based on the area that would be swept out by a line drawn between the Sun and the asteroid during the one-week period. Rank from largest to smallest....

Orbits of four different planets around the same star are shown.
The masses of the planets, expressed in terms of the mass M of the
smallest planet, can be found in the included table, while the
relative sizes of the orbits can be determined from the diagram.
Assume that the mass of the star is much larger than the mass of
the planets. Rank the period T of the four orbits, from longest to
shortest.

ASTRONOMY (Ranking Reflecting Telescopes and Light Collection )
Part A Listed following are the names and mirror diameters for six of the world’s greatest reflecting telescopes used to gather visible light. Rank the telescopes from left to right based on their light-collecting area from largest to smallest. For telescopes with more than one mirror, rank-based on the combined light-collecting area of the mirrors.Part B Shown following are the primary mirror arrangements and total light-collecting area of five different telescopes. Each mirror uses a different segmented arrangement, but assume that they...

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
