Answer:
The answer to the questions is;
In terms of standing waves, the listener moves from a location with high amplitude to one with lower amplitude or vibration (anti-node to node)
The distance 4.1 cm is equivalent to λ/4
Explanation:
For standing waves we have is a stationary wave comprising of two opposite direction moving waves that have equal amplitude and frequency, resulting in the superimposition of the waves. As such certain points are fixed along the wave path that is the peaks amplitude of the wave oscillation is constant at a particular point. A node occurring at a point and an anti-node occurring at another fixed point
When the listener moves 4.1 cm he or she has left the anti-node to the node hence the faintness of the sound
The distance from the node to the anti-node is 1/4 wavelength, or 1/4×λ
Therefore 4.1 cm is λ/4
This is the correct answer to your question, "BC shows zero acceleration, and CD shows negative acceleration".

Explanation: I took the test
Planetary rings are ice crystals or particles. These particles are numerous and they are small. Jupiter, Saturn, Uranus and Neptune all have rings and are all Jovian planets.
Saturn has big and numerous rings and are visible from Earth. Jupiter's rings are almost invisible and are dusty. Uranus and Neptune have narrow rings but they are very bright and dense and have very thin dust rings in between. Neptune's rings however are more dense than Uranus' and they seem to make arcs rather than complete circles around the planet.
Gap moons are small moons that orbit within the rings. They cause gaps in the rings because of the gravity of the moons. They push through the ring particles and move them away from each other.
Moons that are further away also affect the rings through resonances. Resonances can launch waves within the rings. Resonances also causes gaps in rings when the moons push on the ring particles repeatedly.
