What is your measurement of speed of sound in air in m/s? The number should have three significant digits. Your Answer: Answer units

The level of sound D in decibels is defined as follows: 10 log (10-16) I where I is the sound intensity in watts per centimeters squared. Determine the level in decibels of a sound with intensity I 10-8 watts ст?

Item 9 Learning Goal: To learn the properties of logarithms and how to manipulate them when solving sound problems. The intensity of sound is the power of the sound waves divided by the area on which they are incident. Intensity is measured in watts per square meter, or W/m². The human ear can detect a remarkable range of sound intensities. The quietest sound that we can hear has an intensity of 10-¹2 W/m², and we begin to feel pain when the intensity reaches 1 W/m². Since the intensities that matter to people in everyday life cover a range of 12 orders of magnitude, intensities are usually converted to a logarithmic scale called the sound intensity level 3, which is measured in decibels (dB). For a given sound intensity I, B is found from the equation ß = (10 dB) log (1). where Io = 1.0 × 10-¹2 W/m². Part A What is the value of log(1,000,000)? Express your answer as an integer. ► View Available Hint(s) The logarithm of x, written log(x), tells you the power to which you would raise 10…

102 kg/m3? What is the speed of sound in benzene, which has a bulk modulus of 1.05 x 109 Pa and a density of 8.76 x 1094.82 km/s

Ocean waves with a wavelength of 40.0 m travel at 5.00 m/s towards a boat at sea. Determine the number of times the boat bobs up and down per minute as a result of encountering the waves.

A f = 2п , Vx (L + 0.8D) f = frequency, in hertz v = 343 meters/second (speed of sound in air) A = area of opening, in m2 V = volume of round cavity, in m³3 L = length of neck, in m D = diameter of neck, in m

During a thunderstorm, 3.0 s elapses between observing a lightning flash and hearing the resulting thunder. Approximately how far away in kilometers and miles was the lightning flash? (Assume the speed of sound is 344 m/s.) km mi

calcualte the speed of sound in correct SI units? c=sqrt(P/ p) P= 201*10^3 Pa  P(air)= 2.33kg/m^3

In the upper atmosphere at altitudes where commercial airlines travel, we find extremely cold tempera-tures. What is the speed of sound (in metric units) for a temperature of -55 ◦ C? Calculate to one decimal.

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, dd, from the source of the sound.A person 14 feet from a jetski, it is 75 decibels loud.How loud is the jetski when the person is 46 feet away? Round your answer to the nearest hundredth.
