- A carousel that is 6.00m in radius has a pair of 600Hz sirens mounted on posts at opposite ends of a diameter. The carousel rotates with an angular velocity of 0.900rad/s. A stationary listener is located at a distance from the carousel. The longest wavelength reaching the listener from the sirens is closest toType of interference that occurs at any location along the medium where the two interfering waves have a displacement in the same direction. Destructive Loose-End Constructive Free-EndDestructive interference always results in a wave with no amplitude. True O False

A) 2 (lambda) B)1/4 (lambda) C)1/2 (lambda) D)(lambda) E)both c and d#772) Three waves are described by the following equations: Y1 = (0.1m) sin[(2лs¯¹)t + (3πm¯¹)x] y2 = (-0.2m) sin[(3πs¯¹)t - (2πm-1)x] y3 = (0.3m) sin[(4πs¯¹)t − (4πm¯¹)x] Rank the wavelengths of these waves from largest to smallest. 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). 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,…
