The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For sound waves, I0 is taken...

9. Sound levels are measured by the logarithmic decibel scale, named after Alexander Graham Bell. The sound level, L, corresponding to an intensity of I, in watts per square metre, is し= 10 log-, where lo is the minimum intensity audible to the human ear. If amplified rock music has a loudness of 120 dB and ordinary conversation has a loudness of 50 dB, how many times louder than ordinary conversation is amplified rock music?

i have some physics questions. If an infant can scream at a sound level of 111.0-dB measured at a distance 11.0-cm from their mouth, how far away should a parent stand so that the child can be seen but not heard? (The threshold of hearing is 0-dB, or equivalently I0 = 10-12-Wm-2.) Assume spherical symmetry for the dispersion of the sound wave energy (this is of course a bad assumption). Answer km How much power is the child putting in...

Suppose that a population of hacteria grows according to the logistic differential equation dP =0.01P-0.0002P2 dt where Pis the population measured in thousands and t is time measured in days. Logistic growth differential equations are often quite difficult to solve. Instead, you will analyze its direction field to acquire infom ation about the solutions to this differential equation. a) Calculate the maximum population M that the sumounding environment can austain. (Note this is also calked the "canying capacity"). Hint: Rewrite...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
