I think c or d bc that’s what my teacher told me
Answer:
Both move slower through densely packed molecules
Explanation:
A transverse wave is one in which the particles of the medium is said to move in a direction that is perpendicular to the direction that the wave moves through. A longitudinal wave is a type of wave whereby the particles of the medium are said to move in a particular direction that is parallel to the direction the wave moves through.
Both waves can travel through a solid medium while only longitudinal waves can only move through liquid medium.
The answer is: psychometric; Piagetian
According to the psychometric approach, the cognitive development could be measured by using numerical assessment with a standardized result. This is similar to Alfred's view who believe that those who give better performance in quantitative measures of variables tend to be more developed.
According to the Piagetian cognitive approach on the other hand, the cognitive development could only be measured by how well an individual is interacting with their biological traits and the environment around them (similar's to Jeanne's view)
