Sound IntensityThe level of sound β (in decibels) with an intensity of I is
where I0 is an intensity of 10–16 watt per square centimeter, corresponding roughly to the faintest sound that can be heard. Determine β(I) for the following.
(a) I = 10–14 watt per square centimeter (whisper)
(b) I = 10–9 watt per square centimeter (busy street comer)
(c) I = 10–6.5 watt per square centimeter (air hammer)
(d) I = 10–4 watt per square centimeter (threshold of pain)

- A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?arrow_forwardThe function f(x)=ex is called the___________ Exponential function. The number eis approximately equal to________.arrow_forwardA bottle of soda with a temperature of 71 Fahrenheit was taken off a shelf and placed ina refrigerator with an internal temperature of 35 .After ten minutes, the internal temperature of thesoda was 63F . Use Newton’s Law of cooling towrite a formula that models this situation. To thenearest degree, what will the temperature of thesoda be after one hour?arrow_forward
- The formula for measuring sound intensity indecibels D is defined by the equation D=10log (II0), where I is the intensity of the sound in wattsper square meter and I0=1012 is the lowest level ofsound that the average person can hear. How manydecibels are emitted from a largeorchestra with asound intensity of 6.3103 watts per square meter?arrow_forwardFind the solution. Decibel gain Find the dB gain of an amplifier when EO=60 volts and EI=0.3 volt. Hint:dBgain=20logEOEI. Round to the nearest decibel.arrow_forwardThe formula for measuring sound intensityin decibels D is defined by the equation D=10log(II0) where I is the intensity of the sound in watts persquare meter and I0=1012 is the lowest level of sound that the average person can hear. How manydecibels are emitted from a rock concert with a sound intensity of 4.7101 watts per square meter?arrow_forward
- Sound Intensity The relationship between the number of decibels and the intensity of a sound I (in watts per square meter) is =10logI1012 Find the intensity I for each decibel level . (a) =60 (b) =135 (c) =1arrow_forwardThe exposure index E1 for a 35 millimeter camera is ameasurement of the amount of light that hits the ?lm.It is determined by the equation EI=log2(f2t),wheref is the f-stop" setting on the camera, and t is theexposure time in seconds. Suppose the f-stop settingis 8 and the desired exposure time is 2 seconds. Whatwill the resulting exposure index he?arrow_forward
