You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T=28.5 degrees celsius. To determine how far you are away from the canyon wall you yell "hello" and hear the echo t=3.05s later. a) calculate the speed of sound in the valley in meters per second, assuming the speed at 0 degrees celsius is 332 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= -1.5 degrees C, how long would it have taken for you to hear the echo, in seconds?
On a warm summer day (29 ∘C∘C), it takes 4.70 ss for an echo to return from a cliff across a lake. On a winter day, it takes 5.10 ss . The speed of sound in air is v≈(331+0.60T)m/sv≈(331+0.60T)m/s, where TT is the temperature in ∘C∘C. What is the temperature on the winter day?
