A gasoline-powered lawn mower produces a sound of 98 decibels. An electric lawn mower produces a sound of 73 decibels. Which statement best describes the comparison between these two types of lawn mowers? Remember, loudness, L, is determined by the following formula: L=10-log(P) L = loudness in decibels (dB) P=power of sound in watts Prer reference power level of 10-12 watts A The gas-powered lawn mower produces a sound that is approxi- mately 320 times more powerful than the electric lawn mower. D The gas-powered lawn mower produces a sound that is approxi- mately 25 times more powerful than the electric lawn mower. C The gas-powered lawn mower produces a sound that is approxi- mately 10²5 times more powerful than the electric lawn mower. The gas-powered lawn mower produces a sound that is approxi- mately 1250 times more powerful than the electric lawn mower.
