Audible Sound. Provided the amplitude is sufficiently great, the human ear can respond to longitudinal waves over a range of frequencies from about 20.0 Hz to about 20.0 kHz. (a) If you were to mark the beginning of each complete wave pattern with a red dot for the long-wavelength sound and a blue dot for the short-wavelength sound, how far apart would the red dots be, and how far apart would the blue dots be? (b) In reality would adjacent dots in each set be far enough apart for you to easily measure their separation with a meter stick? (c) Suppose you repeated part (a) in water, where sound travels at 1480 m>s. How far apart would the dots be in each set? Could you readily measure their separation with a meter stick?
One-dimensional Motion-Lab #1 PHY 1021 Lab Report One-dimensional Motion Introduction In this lab we studied one-dimensional motion. For part 1, we studied constant velocity by connecting tape to a car moving at a uniformed speed and used a timer to calculate marks made per second. For part 2, we studied constant acceleration by sending a car down a ramp connecting to a sensor to calculate the velocity over the time intervals. Procedure Part 1 For Part 1, Constant Velocity, we pulled a piece of paper tape about 30 cm long through a Nakamura timer set at 1/10 s (10 Hz). Next, we set a Pasco motorized car on a trial run next to a metric ruler for a six- second run. We estimated for a six second run, we would need a piece of tape about 21 cm long. We used this measurement
