Question

What, in units of Pascals, is the peak-peak amplitude of a sine wave that has an instantanous amplitude at 90degree of 3Pa? smallCircle 1/6 smallCircle 6 smallCircle -6 smallCircle 1/2 smallCircle 0 What is the maximum amplitude of a sine wave that has a peak-peak amplitude of 17Pa? smallCircle 25.5 smallCircle 34 smallCircle 17 smallCircle 8.5 smallCircle Cannot be determined What is the root-mean-square (rms) amplitude, in units of Pa. of a sine wave with a maximum amplitude of 5 Pa? smallCircle 3.18 smallCircle 3.535 smallCircle 5.353

Explanation / Answer

12. peak-peak amplitude = 2x3 = 6

13. max amplitude = 17/2 = 8.5

14. Rms = 5/(2)0.5 = 3.535
