Algebra.Com's Answer #197477 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! use formula l=10*log where the loudness of sound in descibels is determined by i,the number of watts per square meter,produced by soundwave and io=10^-12.what is the intensity of a noise measured at 53dB? \n" ); document.write( "choose one of these answers \n" ); document.write( "--- \n" ); document.write( "53 = 10log(i/io) \n" ); document.write( "5.3 = log(i/i^-12) \n" ); document.write( "5.3 = log(i)-log(10^-12) \n" ); document.write( "5.3 = logi +12 \n" ); document.write( "log(i) = -6.7 \n" ); document.write( "i = 2 x 10^-7 \n" ); document.write( "---------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "----------------------\r \n" ); document.write( "\n" ); document.write( "1.5.3 x 10 (-10) \n" ); document.write( "2. 2 x 10(-7) \n" ); document.write( "3. 2 x 10 (14) \n" ); document.write( "4. 2 x 10 (-6) \n" ); document.write( " \n" ); document.write( " |
