Unformatted text preview: Answer the following questions based on the following figure. 1. What is the peak amplitude of this wave? What is the instantaneous amplitude of this wave at the following times: 0, 0.75, 1.5, 2.25, and 3 seconds? Based on the above values, calculate the RMS amplitude of this wave. Would the RMS amplitude be different if instantaneous amplitudes at times 0.125, 0.625, 1.125, 1.625, and 2.125 s were used? In your opinion, is it better to pick fewer or more points to calculate RMS amplitudes? 2. 3. 4. 5. Calculate the frequency and time period of the following wave. Answer the following questions.
1. Wave A has a frequency of 100 Hz. Wave B completes one cycle in 10 s. What can be said about the two waves? a. They have the same frequency b. They have the same amplitude c. Wave A has a higher frequency than wave B d. Wave B has a higher frequency than wave A Wave C completes 300 cycles in 30 seconds. Calculate the time period and frequency of this wave. 2. Plot the waveform (time and displacement on horizontal and vertical axes, respectively) of wave C (from the previous question) showing at least three complete cycles. Assume that the peak displacement of wave C is 10 mm. ...
