- Water ripples are produced by making a cork oscillate up and down at a frequency of 8Hz. The peaks of the ripples are0.02 meters apart. What is the speed of the water ripples? Calculate to one decimal.How long a tape does a police officer need to record a 3-minute confession at an operating speed of 6.5 inches per second?Calculate the uncertainty using the equation below and find the answer.
- Can you walk me through using STK to verify this result? I have STK 12 for referance.2) You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 32° C. To determine how far you are away from the canyon wall you yell “Hello” and hear the echo t = 3.5 s later. Randomized Variables T = 32° C t = 3.5 s a) Calculate the speed of sound in the valley in meters per second, assuming the speed at 0° C is 330 m/s. b) How far are you from the canyon wall, in meters? c) If you stood at the same point on a cold morning where the temperature was T2 = -3.5 degrees C, how long would it have taken for you to hear the echo, in seconds?Could someone please explain to me what a negative relative error means? I got a relative error value of -30% in my lap and am unsure of what this means in terms of accuracy and percision of my lab data/experiment. Any help would be great thank you!
