1) The equation below describes the variation of pressure at different positions and times (relative to atmospheric pressure) caused by a sound wave: t AP = (2.0 N/m²) cos 2 (0.010s Say everything you can about this wave. Scientific Abilities Is able to extract the information from representations correctly Missing No visible attempt is made to extract information from the problem text. Inadequate Information that is extracted contains errors such as labeling quantities incorrectly, mixing up initial and final states, choosing a wrong system, etc. Physical quantities have no subscripts (when those are needed). x 3.4m Needs Improvement Some of the information is extracted correctly, but not all of the information. For example, physical quantities are represented with numbers there are no units. Or directions are missing. Subscripts for physical quantities are either Adequate All necessary information. has been extracted correctly and written in a comprehensible way. Objects, systems, physical quantities, initial and final states, etc. are identified correctly and units are correct. Physical quantities have consistent subscripts. Sketch a graph showing the change in pressure at a single point as a function of time. Scientific Abilities Is able to construct new representations from previous representations Missing No attempt is made to construct a different representation. Inadequate Representations are attempted but use incorrect information or the representation does not agree with the information used. Needs Improvement Representations are created without mistakes, but there is information missing, i.e. labels, variables. Adequate Representations are constructed with all given (or understood) information and contain no major flaws. Sketch a graph showing the change in pressure at all points at a single time.
