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
The concept that underlies the other would be :
effective nuclear charge zeff
It control Ip and electron affinity by determining attractive force between atom and the electron
it underlies atomic size because it draws the valence electron closer
hope this helps
Answer:
A. It said that the planets have epicycles.
Explanation:
Ptolemy's model had Earth at the center, and the moon's revolved around the planets instead of the planets revolving around the moon and sun. The planets' orbits' moved instead of the planets as well.
