Physics Spreadsheet 20 15-Nov-07 By: Robert Rogers Question 1: Enter the length of the string (m): Enter the number of wavelengths: Enter the mass of the string (g): Enter the frequency of vibration (Hz): Enter the peak to valley displacement (m): Power along the string (W): #DIV/0! Question 2: Enter the average power output (W): Enter the distance from the source (m): Intensity of the waves (W/m^2): #DIV/0! Question 3: Enter the reduced sound level (dB): Distance from point source (m): 0 Question 4: Figure it out yourselves, partly because I cannot mathematically compute it. Also, because I am extremely lazy and don't want to use Mathematica. Question 5: Enter the ambulance velocity (m/s): Enter the car velocity (m/s): Enter the siren frequency (Hz): Enter the velocity of sound (m/s): Wavelength of sound person detects (m): #DIV/0! Question 6: Frequency the driver of the car hears (Hz): #DIV/0! Question 7: Enter the speed of sound in air (m/s):

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
