Lets go ahead and assume that we have a sound source is generating 180 W of sound energy that is going in all directions. And also lets say that there is a women that is moving toward the source at 0.40 m/s. When she gets right to 50 m away,

a. What is the intensity of sound in dB?

b. What is the rate at which the intensity of sound is increasing in dB/s?

An ultrasound machine in a hospital uses a sound source at 5.10000MHz. Assuming that the speed of the ultrasound in the body is same as water (1440 m/s), determine the wavelength in the body. If blood cells are moving towards the sound source at a speed of 0.8 m/s, at what frequency do the crests of the sound wave pass through the blood cell? What is the frequency of the sound waves reflected back towards the source by the blood...

Please show all your work. A source of sound is located in a room a distance “L” from a wall. The room temperature is 72°F. AN observer is located between the source and the wall at 103 cm from the wall. The observer can hear a loud sound at the 3rd harmonic and the sound fades at the 4th harmonic. What is the velocity of sound in the room? What is the frequency at which the observer can hear the...

In order to get going fast, eagles will use a technique called stooping, in which they dive nearly straight down and tuck in their wings to reduce their surface area. While stooping, a 6-kg golden eagle can reach speeds of up to 53 m/s. While golden eagles are not very vocal, they sometimes make a weak, high-pitched sound. Suppose that while traveling at maximum speed, a golden eagle heads directly towards a pigeon while emitting a sound at 1.1 kHz....

Example of observation: AJ is standing in the play room facing the toy bin. She bends down and grasps the end of a string attached to a duck pull toy. She pulls the duck out of the bin by the string using her right hand and bends her knees and squats down next to it. With her right forefinger she pushes a button on the duck’s back which plays a song. She stands up holding the string in her right...

SECURING THE WORKFORCE Diversity management in X-tech, a Japanese organisation This case is intended to be used as a basis for class discussion rather than as an illustration of the effective or ineffective handling of an administrative situation. The name of the company is disguised. INTRODUCTION In light of demographic concerns, in 2012, the Japanese government initiated an effort to change the work environment in order to secure the workforce of the future. Japan is world renowned for its...

What role could the governance of ethics have played if it had been in existence in the organization? Assess the leadership of Enron from an ethical perspective. THE FALL OF ENRON: A STAKEHOLDER FAILURE Once upon a time, there was a gleaming headquarters office tower in Houston, with a giant tilted "£"' in front, slowly revolving in the Texas sun. The Enron Corporation, which once ranked among the top Fortune 500 companies, collapsed in 2001 under a mountain of debt...
