When a politician makes a speech that is televised and transmitted live, who hears his words first? 1) a person in the crowd in front of the politician, listening from 50m away OR 2) a person watching the televised recording from 3000km away, with his ear right up against the television set? Select the correct answer Because light travels faster than sound. The column resonates with the sound waves more than with the light waves The column can transmit sound waves but not light waves. Sound waves have much longer wavelengths than light waves and therefore are more able to bend around the column. Your Answer Sound waves have much shorter wavelengths than light waves and therefore are more able to bend around the column

"Companies should focus on financial measures of quality because these are the only measures of quality that can be linked to bottom-line performance." Do you agree? Explain. A. Yes, companies should emphasize financial measures of quality. Total COQ provides a measure of quality performance for evaluating trade-offs among prevention costs, appraisal costs, internal failure costs, and external failure costs. B. Yes, companies should emphasize financial measures of quality. Financial measures of quality are consistent with the attention-directing role of management accounting. COQ measures focus managers' attention on the costs of poor quality. C. No, companies should emphasize nonfinancial measures of quality over financial measures. Without nonfinancial quality measures, quality problems might not be identified until it is too late. D. No, companies should emphasize financial as well as nonfinancial measures of quality, such as customer satisfaction, employee satisfaction and defect rates. Nonfinancial measures are easier for employees to understand; they direct attention to physical processes that help managers identify precise problem areas in need of improvement, which can be linked to bottom-line performance.
