Question asked by Filo student

During a sound check for the Strauss Performing Arts Center at UNO, a technician measures the following unweighted L for the octave bands listed: Frequency (Hz): 63 125 250 500 1000 2000 4000 8000 Lp (dB re 20 Pa): 85 79 73 80 92 101 91 84 a. Calculate the total unweighted L across these bands by the exact method. b. Calculate the total unweighted L across these bands by the approximate method. What is the error in dB of the approximate solution from the exact one found in (a)? Calculate the total A-weighted Lp across these bands by the exact method. d. Calculate the total A-weighted Lp across these bands by the approximate method. What is the error in dB of the approximate solution from the exact one found in (c)?

solve 5.Bring the charged sphere near the ncutral sphere, and then momentarily ground the neutral sphere.What charge does it now have? Describe force versus distance for this case.Compare this to force versus distance for the charged and neutral sphere. 6. Look at the 5 curves of force versus distance on the graph.Explain whv each looks as it does,and why the others look different. Sketch possible charge configurations on the two spheres to aid in your explanations. 7.Explain in detail why it is possible for two conductors, in certain circumstances,to attract even if they both have a net positive charge. Under what circumstances does this occur, and why?
